This quick puzzle is inspired by my favourite friendly rock monster.
The Puzzle
The party enters a 10ft wide, circular corridor that continues beyond their vision in both directions. The walls feature a repeating pattern, only broken by the door that they came through.
Travelling in either direction, characters will find themselves approaching the door again from the opposite side. The corridor will return a creature to the starting point as they no longer have a line of sight with the door. The party probably won't realise this is happening until they go into the door again, so you can have fun with it.
To complete this puzzle, the party must complete a full circle of the corridor without being sent back to the beginning. At this point they will find a different looking door that allows them to progress.
The Solution
The key to solving this puzzle is to create a "chained" line of sight on the door. If characters can see each other AND the door, they wont be returned to the start.
To do this, the characters must place themselves around the perimeter of the corridor, creating a chain: The first character sees the door and the second character, the second character sees the first and the third, and so on...
With an outer wall diameter of 100-140ft, the party will need 5 creatures to complete the puzzle, but your players may also use familiars, summoned creatures or cleverly placed mirrored surfaces as part of the chain.
Remember, that once they can see the new door, they will need to get to it without breaking line of sight with each other. If this happens, and the group gets split, they can all return to the original door by moving around the corridor.
