Stratego
Description
Two players position their game pieces on a chess-like board but in a configuration unknown to each other: token values can only be seen from one side. On a turn a player moves a token horizontally or vertically. If the token lands on a square occupied by the enemy, the two tokens are revealed and their values compared. If a special power doesn't come into play, the lowest value is taken off the board. To win, a player must discover the opponent's flag piece.
