Across all adventure games, one common theme amongst the truly profound, mind-bending puzzles I’ve seen has been the idea of repurposing — taking an item, location, character or verb that seems to be designed for one purpose and using it for another. Essentially, for a player to solve the puzzle, the rules of the universe itself need to be expanded.
Examples amongst the All the Adventures project include the final puzzle of Mystery Fun House (where what normally would be an ordinary “informational” item gets put to essential use) and the Wumpus puzzle of Adventure 501 (where something originally used merely for transport becomes a weapon).
The puzzle game Baba is You is based around this idea. The rules of a particular level can be changed by modifying the sentences in the world itself. “You” are normally the small white creature as expressed by the sentence “BABA IS YOU”, but if you push the word “ROCK” to form “ROCK IS YOU” you switch to controlling the rocks (all of them, at once).
The Vial of Doom has a repurposing puzzle near the end which is astounding and does a trick I’ve never seen before.

This is Roger M. Wilcox’s seventh game. Sometime after 1980 he distributed it to Usenet (but much earlier than his other games) and there’s even an Interactive Fiction Database entry.
He based on it off his own 25-page short story he wrote a year before, which was “influenced just a teensy weensy bit by Michael Moorcock’s multiverse.”
In many ways, this game was a watershed in my adventure-game-authoring career, as I originally thought the story was way too complicated to make an adventure game out of … until I read an article about Greg Hassett’s “World’s Edge” adventure and turned green with envy and grim with determination. I considered it my first “good” TRS-80 adventure game; it was the 7th I’d written, and 14 more would follow it (15, if you count that Star Trek adventure where you can’t even pick things up). When the IBM PC became available to me in 1983, I ported this game to GWBASIC.
I played a QBASIC derivative of the GWBASIC source.
There’s no motivation or plot to start; the player is supposed to mess around since there’s nothing else to do. Nearby the starting room you find a shovel, and if you dig here you find an underground pyramid with a portal.
Touching the portal leads to a room with a plastic container and a lead box, and opening the lead box leads to the Vial of the game.
Chaos is the bad guy, Law is the good guy; unlike the usual Dungeons and Dragons alignment charts (where it’s possible to be Lawful Evil or Chaotic Good) the Moorcock-verse is a straight Law vs. Chaos opposition which is intense enough to warrant its own Wikipedia page. We’re tasked with destroying the Vial and are on the hunt for a turquoise gem, a fire opal, cobra venom, a basilisk eye, octopus ink, and an alabaster bowl.
The vial ends up being used quite a few times throughout the game. Right from the start after taking the lead box, a mummy blocks the way, but as long as you WEAR VIAL, you can PUNCH MUMMY:
Baam! You made it fly apart!
To get out of the pyramid area, you need to DIG again but must be wearing the vial to have enough strength to dig straight up. However (as the screenshot above warns) you can’t wear the vial for much longer, because if you try to step much farther while wearing the vial, you get consumed by Chaos.
However, the vial is still useful; if you WAVE VIAL you can distract people or get a burst of strength.
You are in a pawn shop. Visible items:
Store clerk. Large dagger. Turquois gem. Sleeping pill.
Obvious exits: south
The clerk wants money for the items, but you can just WAVE VIAL
The clerk is now hypnotized.
and use the five-finger discount method.
The parser is unfortunately very awkward; the game even states upfront “I know the verbs STICK, SWING, and PLUCK” but it’s hard to know where they get used. STICK turns out to be handy for STICK COBRA
Into where (one word)? CONTAINER
Squirt! The container fills with venom, and just as quickly, the cobra awakes!
I admit not to thinking through the above action at all, but simply running through every verb possible before the event happened.
I got stuck on one parser issue enough I had to poke through the source code. In front of a jewelry store there is a guard with a thermos of coffee, and I knew the sleeping pill that I already had lifted from the pawn shop would be useful, but I could not for the life of me apply one to the other. The right sequence turns out to be SWING GUARD. THROW PILL. (That doesn’t sound terrible, but I had went through many permutations of PUT PILL and INSERT PILL already, and PUT is even an understood verb, just not the one the game wants.)
At least the actions on a story level are fun. It’s as if the author built up a number of set pieces and only worried about if it was possible to communicate after the fact; at least you get to pluck an eyeball directly from a basilisk and suck ink from a sleeping octopus.
Getting away from the aforementioned octopus triggers the final battle, right back at where we started the game.
You’re still able to go back here and mop up any missing ingredients, but I was led astray a long time because I assumed the way to win and stop the giant battle was to finish the ritual, and I had no bowl. Being granted “great strength” by Law was the key. Perhaps a better clue would have been to use a longer phrase, like “enormous strength, more than you’ve ever felt before”.
I’ve given enough clues you can theoretically try solving the puzzle yourself before going on.
Picture here for spoiler space; this is from a parody ad Roger M. Wilcox made for the game.
The right action is to dig back down to the pyramid location (remember, we’re back at the start of the game), but rather than entering the pyramid, pick up the pyramid itself, go back up, and throw the pyramid at the Chaos giant.
Whump! Chaos is down! Law wins the fight, and says: Make the mixture here!
This absolutely boggled me; the game took what normally was an enterable location and turned it into an object you can pick up.
After taking down Chaos, the Vial still needs to be destroyed. You find an alabaster bowl in the rubble, which is enough to finish the ritual.
The vial vibrates, getting ready to explode. Oh, by the way — ** YET ** !!
> RUN
You’re on the side of a mountain. Visible items:Wishing rock.
Obvious exits: up
The vial goes off in a red, Chaotic mushroom cloud.
you have only six (6) seconds until the fireball reaches you!
One more action leads to safety:
Renga in Blue
