Discon is an abstract game for 2-4 players. A 10x10 grid is covered with stackable discs in four different colours, save for the corners, which are numbered and act as the players' starting positions. Each player has 6 "roof" discs which enter the board in their corner. Roofs move in an L-shape, like a knight in chess, and collect the discs in the squares they move to. The game ends when all discs are collected, at which point towers are scored according to height and colour composition.
