Maze Craze

A competitive game of memory and planning!

Its a race to leave the maze. There are 3 main versions of the game.

  1. Race: A basic version of the game. First to leave the maze wins
  2. Robbers: There are 2 robbers randomly traversing the maze. If you are captured by the robbers, you lose the game, and receive -1 reward, and will be done. The player that has not been captured will not receive any reward, but they can still exit the maze and win, scoring +1 reward.
  3. Capture: Each player have to capture all 3 robbers before you are able to exit the maze. Additionally, you can confuse your opponent (and yourself, if you are not careful!) by creating a block that looks identical to a wall in the maze, but all players can pass through it. You can only create one wall at a time, when you create a new one, the old one disappears.

The first player to leave the maze scores +1, the other player scores -1 (unless that other player has already been captured in Robbers mode).

Official Maze craze manual. Note that the table of modes has some inaccuracies. In particular, game mode 12 has Blockade enabled, not mode 11.
