To begin a game, you start with the board completely empty, and then players have to choose their marbles then they can place the movable grid anywhere within the board Now just place it right here in the center, then players take turns placing their marbles in any unoccupied space within the grid After a player has made two or more moves on each of their turns they have three options, They can either add another marble to any open space within the grid or they can place any of their marbles in any unoccupied space within the grid or they can actually move the grid or they can actually move the grid, one space right or left up or down or even diagonally, players keep going like this until someone gets three in a row!
