Equipment: Four double sided tiles: marshal-spy, miner-miner, bomb-colonel, general-colonel, as shown in this picture:
Goal of the game: to be the first player to ten points.
Before each turn the tiles are mixed under the table, it is important to turn the tiles while mixing them. They are then placed standing up between the players so that each player can see only one side of each tile. Each player secretly selects a figure on their side by holding a number of fingers below the table indicating the tile's position. The players simultaneously reveal their selected number.
Each of them wins against some of the other types.
