The game is similar to the traditional game of tic-tac-toe, but is played on four 4×4 grids arranged side by side. To win, a player must place four of their symbols on four fields in a vertical, horizontal or diagonal pattern, either on one grid or evenly spaced across all four grids. This gives a total of 76 possible ways to win. The game adds a choice of four difficulty levels, two types of tactics and a duration of gameplay or turn.
