On a 3x3 board with 9 numbered squares, the goal is to win rounds by covering the most squares with tiles. First, 9 of a player's 27 pieces are randomly placed on the squares at the same time. Then the players take turns to draw 2 pieces each from the bag and place them one after the other in the squares 1-9. Then the players take turns, there are two possibilities: Either move one of your own stones as you wish, or cover a square in which there are exactly 5 of your own stones, no matter how many opposing stones are in it. If no more fields can be covered, the game ends, whoever has covered more fields wins the round, with 3 won rounds you win the game. —user summary
