Infinity Dungeon is an absurdist RPG that is playable in thirty minutes to an hour for lighthearted dungeon crawling.
The game focuses more on puzzle solving than combat or social encounters, as each room in the dungeon presents a unique puzzle for players to solve.
Infinity Dungeon uses a Peer-Review System for resolving encounters. Other party members vote on how likely your solution is to clear a room, and you are given bonuses based on how likely other players think you are to succeed. A single d20 roll determines whether a puzzle's solution succeeds or fails, with success moving the party to the next room, and failure spelling the untimely death of the player.
