Age 3+ Like tic-tac-toe, the game starts with the first player placing a ball anywhere on the board. Wherever they place the ball within the 9x9 box, determines where the following player can place a ball. Say the first player decides to play in the top right hole of a 9x9 box, the second player can now only place a marble in one of the open holes in the top right box. The first player to win 5 or the majority of the squares is the winner! Skills Strategy Problem- solving skills Group play Content White and Green marbles
