I wanted something strictly traditional to trudge through, so I poked through my game list and came across Crystal Cave, a game from an unknown year and an unknown author but one that was made by modifying the original Crowther/Woods source code to Adventure. We have access to it because Kevin O’Gorman ported it to C in the late 80s from UNIVAC FORTRAN, of all things.
Boy howdy, did it break “traditional” in half.
(Year and author unknown-ish — I found someone asking about it in March 1984. 1980 is a decent educated guess. I also have a strong suspicion who the author is and may even be able to verify 100%, but I’ll get into that in a later post.)
If UNIVAC is ringing a bell, you may have heard about it as being the world’s first commercially sold computer. Here’s a spot from an educational video (1950-1952ish) explaining how the keystrokes on the keyboard are turned into electrical impulses.
By 1980 (or so) our code in question was running on a UNIVAC 1100, which had at least moved past vacuum tubes. It was still bulky.

We’ve certainly seen many variants of Adventure now:
This isn’t like any of those. This is a brand-new game which just used the original source code as the base for writing a text adventure. There are very few elements unchanged (most notably, the dwarves seem to be identical to original Adventure).
The port I was playing gave me warning: while the game has some similar elements to Adventure it very intentionally deviates from them in their use, almost like a running joke. Acheton (1978) played with this idea a bit …
You are standing in the depression.
There is a 3×3 steel grate set in the ground nearby.
The grate is open.
> d
You fall into a well. The water is icy cold, and you rapidly die of hypothermia.
… but Crystal Cave grabs the idea, runs with it, vaults over the wall with it, lights it on fire, does an arts-and-crafts project with the remains, then lights it on fire again just for good measure.
You are standing before a barn at the northern end of a road. To the east is a pasture. To the west and north are woods. There are well-worn paths in several directions.
A Boy Scout compass is lying nearby.
>in
You’re in the barn. It has been converted to quarters for spelunkers.
There are electric lights, and a number of mattresses strewn about.
There are some keys on the ground here.
There is a shiny brass lamp nearby.
Your wallet is here, containing 1 dollar in change.
There is a shower here.
There is a cola machine in one corner. The instructions read:
“DROP CHANGE HERE TO GET A COLA.”
Here’s the start. Nothing too unusual so far, except the standard-issue bottle you get at the start of the game comes out of a cola machine.
Where things get odd is upon arriving to the caves:
You are at a stream exiting from a cliff. A sign says:
“CRYSTAL CAVE PARKING LOT.
PLEASE FOLLOW PATH BESIDE STREAM
NORTH TO CAVE ENTRANCE.”
> n
You are at the mouth of the cave.
Ranger Rick cautions you not to take or break anything in the cave.
The gate is locked, and guarded by a Ranger. A sign says:
“PAY RANGER FOR ADMISSION”.
> pay ranger
You are inside the entrance. A stream exits here. A path runs beside the stream.
The gate opens easily from the inside. A sign says:
“PERSONS LEAVING MUST RE-PAY TO REENTER”.
There is an ancient indian pot here.
Let’s back up to be clear: the opening is designed like a realistic visit to an actual National Park. (Except the reference to Ranger Rick suggests you’re talking to a raccoon, but that never gets spelled out.) The opening section is filled with realistic cave features. Like here …
You are in a long flat room, sloping along a trench in the floor. There is a hole in the ceiling, but you can’t reach it.
There are gypsum flowers here.
… or here:
You are at the intersection of three passages. One rises slightly, one drops rapidly.
There are helictites on the walls.
If you try to touch any of the features, they break and Ranger Rick shows up to chastise you.
The ceiling is covered with soda-straw stalactites.
> get stalactite
There is a Ranger behind you! He says:
“I told you not to take or break anything! Don’t do it again!”
You’re at clock shop.
The ground is covered with pieces of broken soda-straws.
Hence, as what I’m sure is a shock to adventurers everywhere, there are many “items” at the start that you must actively avoid taking and are there purely as realistic cave scenery.
This section is fairly extensive (it took me several hours) and the author clearly did some research; it takes a bit of a puzzle-solving leap (where it helps to know something about caves!) to break into the “inside section” where there are actual treasures you can get and dwarves and a dragon and so on; I’ll save that for next time.
My map of the “realistic” portion of the caves. The east side includes a lake with a boat. You can attempt to sneak into the far west side using a rope but Ranger Rick kicks you out.
ADD: Based on the conversation with Bob in the comments and some other research, I am moving the date to 1977. There is still a question mark attached, but that makes the game very early, before even the first wave of modified versions of Adventure like Adventure II came out. The game includes enough elements that are from the Woods version of Adventure (which we know wasn’t started until March 1977) that I’m not putting it any earlier than that; Bob graduated high school (where he saw the game) in 1977 so that does set a hard limit on there being some sort of version. The only way 1976 would be possible is if a portion of the game was based on the Crowther-only version of Adventure, but even then the majority of the game would have needed to be post-Woods.
One of the less-common Patterns I’ve noticed with games is to take an action which is somewhat abstracted (slaying generic monsters, say) and add personalities and/or ramifications (slaying monsters that turn out to have names and families, you monster). This sort of exercise could be performed on the standard treasure hunt, where the game chastises you for stealing stuff and points out how bad a person you are for playing a game. (This can occasionally be effective but is also wearying in the “you were helping the bad guy the whole time!” plot twist sort of way.)
The opening conceit of Crystal Caves runs along similar lines: having a cave realistically made where touching things will break them and a ranger constantly chastizing you for your plundering adventure sensibilities.
Except here there’s an “inner game” and the change happens, the ranger is never seen from again. (Except, maybe he’ll come back in the endgame?)
You are at the upper end of the misty lake.
You are afloat in a small boat.
There is a large rimstone dam here. Behind it, a pool of water spills steadily over the dam. The ceiling dips into the pool.
This is the location where I hinted at last time that it helps to know something about real caves. I admit my Zork training initially made me think of a human-built dam, but “rimstone dam” refers to a natural cave formation.
Because we aren’t talking about a giant concrete structure, the next action makes more sense. I don’t think any rimstone dams are holding back giant bodies of water as implied, but since this is the barrier between reality and fantasy, it works out:
> BREAK DAM
The dam crashes open with a mighty roar. A gigantic wall of water leaps across the lake and down the stream passage, destroying everything in its path.
You have to be careful to stow away your boat so it isn’t swept away, but otherwise, this will reveal the inner game as well as jam the front gate so you can’t go through anymore.
You are in a large hall with a pool of water. To the south, a waterfall thunders into the pool, and flows out through a passage to the east. To the west, a hole in the wall looms beyond a small beach.
You are afloat in a small boat.
The classic Adventure dwarves start attacking you here (and behave exactly as in original Adventure) and the pirate is also active (and will take any treasures he steals to his “grotto”, although I have no idea where that is). The geography is otherwise entirely different.
The Hall of the Mountain King has expanded to nine rooms. In the center is a throne which launches you in the air.
> W
You are in the center of the Hall of the Mountain King, a large octagonal room. There are passages on all sides!
There is a large, bejeweled throne here.
> SIT
As you sit, you notice the inscription–“Siege Perilous — Nobles only.” With a fearful roar, the throne hurls you straight up — plastering you on the roof of the cave!
To the northwest is a “bugbear” (although close in behavior to a bear; I think the name is from Dungeons and Dragons but bugbears in that game are humanoids). It is chained to the wall just like the classic one from Crowther/Woods Adventure, but if you feed it, it becomes a “well-fed” bugbear and still happy to attack you.
There’s a “King’s Dungeon” complex off to the southwest leading to a crypt. The crypt has a “Fell King” with an iron crown who will start chasing you if you try to take the iron crown. (You can run all the way back to the throne, where sitting while holding the crown isn’t fatal any more … but it doesn’t seem to help in stopping the Fell King anyway.)
The Crypt also has a “ruby medallion” which I haven’t fulled worked out, but seems to let out a glow every time an enemy is nearby, essentially behaving like the elvish sword from Zork. However, it does count as a treasure, and the Pirate has very grabby fingers, so I haven’t been able to play with it much.
There’s a Wizard’s Tower which you can enter as long as you’re holding a nearby scroll, whereupon you will find a Timemaze.
“p” and “f” here stand for “past” and “future”.
I originally hoped for some crazy “change things in the maze in the past to modify the future” type action, and I supppose it’s *possible* that’s embedded somewhere, but mainly the Timemaze is just a regular maze with two additional exits (past and future). One of the treasures (a scepter) is guarded by a dragon, where the KILL DRAGON trick from the original game doesn’t work. It looks like you can just take the scepter and run if you have some way of resisting fire.
To summarize, my open problems are:
1.) passing the bugbear
2.) defeating / evading the Fell King
3.) finding the Pirate Grotto
4.) stealing the scepter from the dragon
Item #3 is, in essence, the top priority for me because I can’t get much done with treasures being lifted all the time, but “find the hidden place that could be anywhere” type puzzles are intrinsically difficult to just work on.
This one’s going to start “normal”, pass through “slightly strange”, and get “Haunt-level weird” at the end. (If you never got to read about Haunt, you should, since no other game before or since has included references to both Cecil the Sea Serpent and Ronald Reagan’s Secretary of the Interior.)

Last time I was stuck trying to find the pirate’s grotto, and it turned out to be my old nemesis, Missing a Room Exit.
>nw
You are in a secret passage running southeast. A second passage enters from the southwest.
From here I only had marked exits going southeast and southwest, but there’s also an exit to the northwest.
> nw
You are at the south end of a grotto. The floor is sand, sloping off to a beach, and a lake to the west. Faint light is visible to the north. There is evidence of a former passage to the west, but it has collapsed, and there is no way to go in that direction now. At one time in the far distant past, the grotto was obviously used by pirates, and there is the tattered remains of a “Jolly Roger” hanging from the ceiling.
Yes, now that I read it carefully, the text implies you can continue to the northwest, but I missed it anyway.
> n
You are at the north end of a grotto with a sand floor and a lake.
Light filters up from the lake, and you can faintly see an opening to the outside world under water, but it is inaccessible.
There is a ruby medallion here.
There is a heavy lead hammer here.
There is a large sparkling nugget of gold here.
The pirate’s treasure chest is here.
A skeleton is here, clutching a cutlass.
So, fairly easy resolution. I also realized I was interpreting the ruby medallion wrong, and it wasn’t glowing near enemies, but just near secret passages; this netted me an ermine cape and some rare spices.
Slightly more complex was the Siege Perilous throne from last time. One time I tested it I got this message
With a powerful roar, the throne hurls you straight up — you narrowly miss hitting the roof of the cave! Your fall jars every bone in your body, but you find that you are all right.
and I different time I received this message
With a roar, the throne flips you into the air to land on the ground in front of it.
but I was stumped as to what was going on, and had to poke at the source code before I realized there’s a cumulative effect going on; there are multiple “royal” type items and if you have them all something should occur. I also learned it’s a King Arthur reference.
Galahad is the knight for whom the Siege Perilous at Arthur’s table is destined. In the Lancelot, a knight named Brumand, trying to perform an act that Lancelot never dared to do, sits in it and is burned to a crisp. Malory says that Merlin made the Siege Perilous for the greatest Grail knight. When Galahad arrives at Camelot, his name appears on the seat destined for him.
— From The Camelot Project
the crown (mentioned in my last post)
the ermine cape
a platinum orb (from the Time Maze)
a scepter (from the Time Maze, guarded by a dragon)
Getting the platinum orb was technically easy, but when holding it while exiting the maze, I was pounced by a spider.
A giant hairy spider, named “Grendl”, drops from the ceiling, barely missing you. It starts to chase you around the room, trying to get you!
A giant hairy spider is following you, trying to get you!
Again I was rather stuck here, but it turned out to be a simple solution. There’s a sword you just need to be holding.
Grendl pounces – – –
but luckily falls upon your sword, and dies!!
In context, it’s understandable I missed this: I was still reckoning with both the pirate and maximum inventory capacity at the time. In a more recent game I would be able to tuck the entire universe in my back pocket, so I’d already have the sword in my possession without any extra puzzle-solving effort.
The dragon was a little more obtuse, and seems to be intended as an inversion of feeding the food to the bear:
> throw spices
The spices fly through the air, forming a fine cloud. The dragon rears back triumphantly, ready to blast you, when the spices make him sneeze explosively, and his fire is extinguished. A very crestfallen and woe-begone dragon looks up at you and says “Mind if I tag along, Boss?”
Once the dragon goes tame, it follows you around and complains about everything:
The small dragon wails “Can I have some treasure, too?”
A dragon follows you, whimpering “Can I have a match, boss?”
You are being followed by a dragon, who whines “I’m hungry.”
Yes, I think we could all use a little more treasure. With the cape, orb, and scepter in hand, I just needed to grab the crown from the Fell King (who I still haven’t figured out how to defeat) and run. While sprinting away from the Fell King, I managed to sit on the throne with all four special items and get to a new area:
> ne
The Fell King is striding after you!
You’re at the center of the Hall of the Mountain King.
There is a large, bejeweled throne here.
> sit
As you sit, you notice the inscription–“Siege Perilous — Nobles only.” The throne silently tips over, revealing a hidden passage beneath it. This is all that you have time to observe, as you are immediately transported, whirling giddily, throught a region of ominous vague shapes, somber shadows, and sullenly-glowing lights! Finally landing with a crash, you shake your head to clear it, look around, and discover . . . You are at the east side of a garden. A murmuring stream enters from the southeast, and exits through a passage to the east.
(Before going on, notice this is a pretty classy piece of structuring: there’s the “realistic” outside with the ranger, followed by the first inner section, but rather than opening the entire inner game at once, there’s a secondary puzzle that leads to a second inner section. A careful structure can go a long way in making a generic treasure hunt feel dynamic.)
The new area has a relatively standard unicorn and djinni (I haven’t figured out what the deal with either one is yet) but also:
> w
You are in an immense chamber, exiting to the east and west. It is lit by flickering, smoky torches, each of which gives off a vile, greasy, black smoke. Indistinctly visible through the smoke, the walls are seen to be lined with galleries.
There is a unicorn wearing a jeweled collar nearby.
A gigantic idol blocking the far end of the chamber is facing you.
A gigantic orc priest stands before the idol, and says:
“You would be well off to make an offering to out idol!”
The galleries are lined with orcs, silently watching you.
I tried offering various treasures.
The orcs chant “That is not the real thing”, and throw offal.
After they rejected every piece of treasure I was carrying, I contemplated if “that is not the real thing” was intended as a hint.
… wait, they wouldn’t? Would they? I had a bottle of cola from the barn at the start of the game.
> drop bottle
Ok.
The orcs scream “AAIIEEE – – – ‘ORCA-COLA’. IT IS THE REAL THING!!!”
A convulsive groan fills the chamber, as the idol shatters explosively.
Flying shards strike and kill all of the orcs, and narrowly miss you!
All the orcs vanish in greasy black clouds of smoke.
There is a small, exquisite jade idol here.
The giant, angry orc is coming after you!
(For those unfamiliar, Coke Is It! was an April Fools’ Day game where authors took old IF games and added delicious Coke. You drop to your knees and cradle Floyd’s head in your lap. Floyd looks up at his friend with half-open eyes. “Floyd did it … got Coke. Floyd a good friend, huh?” Quietly, you croon Floyd’s favorite song: “I’d Like To Buy The World A Coke”.)
My theory as to Crystal Cave’s authorship got shot down (although in the process I discovered yet another undocumented Adventure variant). I have a secondary theory but it’s going to be harder to test; for now, this game will remain by Anonymous.
The usual “I’m going to spoil the finale” warning applies.
Another public domain picture for spoiler space. This one’s from Australia.
Scene the First
The source code refers to the Fell King as “Arthur”, which is kind of epic. (When William of Malmesbury brought up the possibility of Arthur’s return from the dead, I don’t think this is what he meant.)
> sw
You are being followed by a dragon, who whines “I’m hungry.”
You’re in crypt.
There is a black, finely wrought iron crown here.
There is a massive iron tomb here. On top is a wrought figure of the King…a fell figure of grim visage, wearing a mithril helm, and holding a mace.
> get crown
The tomb crumbles into dust. The graven figure on top rises. He is stalking you, swinging the mace!
Ah, yes, the dragon. Keep in mind he complains every single turn.
> ne
A dragon follows you, whining “I want my treasure back.”
The Fell King is striding after you!
The mace strikes the dragon, killing the poor thing.
You’re in corridor.
The body of a small white dragon lies nearby.
The end of a rope dangles from above.
Alas. This doesn’t have to happen if you do the following action right upon activating the Fell King:
> wave scepter
The Fell King disintegrates into a pile of dust, which rapidly blows away
His helm falls with a crash, and rolls to one side.
You are in a narrow, northeast trending corridor.
Near you is a small helmet made of mithril.
The body of a small white dragon lies nearby.
The end of a rope dangles from above.
I confess I did not figure this out on my own and had to source dive again. It’s vaguely interesting that I had to do so because I’ve been waving scepters to cause magic to happen for a while now. There’s no clue at all to the scepter’s behavior, but again: not unusual. I suppose what is rare is a combat use of “arbitrary magic”; the unwritten rule has been to use waving random devices as utility effects, but never as a direct method of stopping an aggressor.
There’s even sensible reason for this rule: imagine you are fighting an enemy that will kill you in one turn. You want to perform an action to stop the aggressor. Given you have only one turn, testing magic items one by one (and getting clubbed by a mace over and over) can get a bit aggravating. Whereas, if you’re simply wandering the landscape and wanting to try out some ideas, a set of “nothing happens” messages before you hit paydirt isn’t nearly as irritating.
Interlude
Immediately after the Orca-Cola scene, the author(s) left open the floodgates of Wacky Stuff. This (entirely optional) bit starts off painful for multiple reasons but I think the last line redeems it.
> get toad
As you touch the toad, it starts to swell and shange shape. It’s — it’s — it’s turning into a dwarf princes! She — she — she’s — she’s — UGLY!
— VERY UGLY!!!!!!
She’s 3’6″ tall, and 180 lbs., with black, oily, snarly hair, and three large warts on her nose, which separates two beady red eyes that don’t track. She immediately starts to say, in a high-pitched nasal whine, “Trying to pick me up, eh sweetie? Where do you think you get off? I’m a decent broad, and won’t have any of this. Whatcha doing around here? You one of those weird explorers who rip off decent folks, taking their treasures out of the cave? I hope you haven’t found the vault yet . . .”
A cloud of white smoke and a wizard appear. He is garbed in green and violet robes, and says “I really must apologize about this. She has no business in this game; she escaped from another game in the next town. There really is no vault in this cave…she’s referring to the next cave. Sorry again.” With that, he takes her hand, and they start to vanish. As they fade out of sight, you note that she has taken his hat, and is beating him severely about the ears with it.
I want to play a game as the dwarf princess defending her vault from selfish adventurers.
Scene the Second
When the dwarves of Moria dug too greedily and too deep, they awakened a Balrog that slew great King Durin VI and became henceforth known as Durin’s Bane.
> w
The bridge is broken here! Above you, the other side of the break looms out of the darkness . . . Or is it something else?
> jump
You just manage to catch the far edge of the bridge and swing up onto it. You are at the west side of the broken bridge, which quickly leads down to the west side of the fissure, and thence to the west side of the colossal chamber. There seems to be a faint, ominous gleam at the bottom of the fissure. Below you, on the side of the fissure, you can see a small ledge. You can get down to it, but you cannot see a way to get back up.
There is turquoise sand here.
> get sand
Ok.
> d
You are stuck on a ledge on the west side of the fissure. You cannot go up. A strand of Grendl’s web, leading downward, is attached here.
> d
You are on a high, lonely ledge on the side of the fissure. Grendl’s strand passes here and continues.
> d
There is a loathsome balrog here.
You are on a lonely high ledge on the side of the fissure. Grendl’s strand passes here and continues.
The Philosopher’s Stone is here.
> throw sand
The sand spreads out into a fine, stinging cloud. Stricken, and taken off guard, the balrog stumbles back. . .back. . . and falls over the edge. . .down. . .down. . .down. . .and vanishes into the gloom.
Sand. The mightiest weapon of all. Clearly, that’s what the dwarves were lacking when they were driven from Moria. After:
> jump
You drop through an impenetrable gloom. Oppressive fear gathers, clawing at you. You are sinking into the depths of Hell, with no salvation in sight. The clammy, black air whistling past is the only sound filling your fear-crazed mind. You are tumbling endlessly, spinning over and over. Suddenly, you feel your descent slowing! With a rush, you finally come to a landing and find…
You are at the top of the Wizard’s Tower. Finely carved stone steps spiral downward. This chamber has a door on the east side, with the words
“CAUTION: THE TIME MAZE LIES BEYOND”
chiseled above.
Is it possible for something to be picturesque and memorable and bad writing all at the same time? The paragraph is dripping with modifiers in a way I haven’t seen since my 1980s Dungeons and Dragons campaign, and if this text appeared in a book I’d probably just close it and walk away, but in the context of this game (and having just taken out a Balrog with some sand yeah eat it Gandalf) my brain just went “neat!”
Another, More Annoying Interlude
After snagging the Philosopher’s Stone and a few other items I thought I had all the treasures, so I did the customary thing in Adventure-clones: find a place where I could leave my lantern off and type WAIT a lot. (And since four characters started to get annoying, I switched to typing I and took inventory a lot.) There normally is a “the cave is closing” type message, but after 100 or so turns I got nothing.
Another source dive, this time into the objects. And … of course I missed one. The very first one listed in cvobj.c, in fact.
{“several diamonds”, “There are diamonds here.\n”, 116},
I suspected, from the room number, that the diamonds were in the Timemaze, but I had mapped that area thoroughly. Resolving my dilemma took stepping through the maze map source code line by line until I realized what I was missing.
I’m not even sure how I would have done this! My guess is I thought I was in the room marked “D” when I tested the “past” exit but I was actually in “A”. One mapping mistake. Grrr.
Scene the Third, Whereupon the Cave Is Closing This Time for Real
The sepulchral voice intones, “The cave is now closed.” As the echoes fade, there is a blinding flash of light (and a small puff of white smoke). . . . You immediately feel the menacing presence of hundreds of pairs of unseen eyes upon you. As your eyes re-focus, you look around and find. . .
You are at the north side of an immense, high-walled arena. The center of the arena is occupied by a colossal jade idol. In the north wall, behind you, is a door.
Ah, the endgame. Where most large treasure hunts so far have fallen down. (Most atrociously in Adventure 550, which was otherwise a good game.)
> se
You are at the east side of an immense, high-walled arena. The center of the arena is occupied by a colossal jade idol, facing you. In the east wall, behind you, is a door.
> e
You are in the repository, where all of the implements and paraphernalia
of the cave expedition are stored! The only exit is to the west.
There is a little axe here.
There is a long sword here.
There is a broad sword here.
There is a spear here.
There is a short sword here.
There is a bow here.
There is a dagger here.
There is a quarterstaff here.
There is a halberd here.
There is armor here.
There is a “heater” shield here.
There is a round shield here.
There is a tall shield here.
There is a cuirass here.
Your reflection peers back at you from a mirror on the wall.
Wrr, is this going to take the Acheton approach and have you fight a bunch of enemies, needing to choose the right weapon each time?
> w
As you step out the door, your image also steps from the mirror, and follows you! Armed and armored exactly as you, *YOU* are your exact match, except that your good nature is reflected as *YOUR* evil nature. *YOU* will kill you, unless you destroy *YOURSELF* first. *YOU* are circling yourself warily, looking for an opening to attack.
Nope, just the one enemy. The resolution is fairly simple, so feel free to hit pause on your podcast device … er …. I mean stop reading for a moment and try to figure out how to win before I share the conclusion.

> break mirror
The mirror shatters explosively, destroying *YOU*! You are thrown backward, throught the dorr, into the arena, where your screaming fans flock down around you, pick you up, and carry you off to a month-long revel honoring the glorious cave conqueror. . .
You scored 487 out of a possible 515, using 493 turns. You have reached “Junior Master” status.
I am not sure what’s with the score, and while the game was fun (despite the Timemaze) I don’t feel the dying need to work out where the missing points are.
…
For those waiting to get to try The Public Caves, it’s up at archive.org (just search for “Public Caves”) but I haven’t been able to get the “play online” feature to work. I’ll let y’all know as soon as I’ve resolved the issue.
As far as what I’m playing next, I have no idea. I still have Star Trek to get through (and I promise I’ll get something up about it next week) but there’s still a wide range of targets to hit in 1980, including our first non-English game that I need to play in its original language (since it has never been translated). It’s a language I know (well, knew) nothing about. Yes, folks, I am learning a language just for your entertainment.
