A move consists of clicking on a square that does not belong to your opponent.

The move increases the points in the square by one.

At the start of the game, each square has one point, is painted in a neutral color and has no owner.

Each player has a color to mark the ownership of squares.

By clicking a square that has no owner, the player becomes the owner of that square and it changes its color to the player's color. Simultaneously the square’s value is increased by one.

If a square has more points than it has neighbors, one point jumps to each of the neighbors, leaving only one point in the original square.

During such a move, all the neighboring squares become owned by the player who moved and so do all of their points, even if the neighbors were neutral or owned by the other player before.

Neighbors are the squares above, below, left and right, but not any diagonally located squares. Corner squares have only two neighbors, while side squares have three, and centre squares have four neighbors.

If a move leaves a neighbor with a maximum number of points, the move continues automatically to the neighbor's neighbors and so on, in a cascade. A large number of squares can change ownership during such a move.

The winner is the player who ends up owning all the squares.
