A move consists of clicking on a cube that does not belong to your opponent.
The move increases the points in the cube by one.
At the start of the game, each cube has one point, is painted in a neutral color and has no owner.
Each player has a color to mark the ownership of cubes.
By clicking a cube that has no owner, the player becomes the owner of that cube and it changes its color to the player's color. Simultaneously the cube’s value is increased by one.
If a cube has more points than it has neighbors, one point jumps to each of the neighbors.
During such a move, all the neighboring cubes 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.
Neighbors are the cubes located above, below, at left or at right, but not diagonally. Corner cubes have two neighbors, edge cubes have three and center cubes have four.
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 cubes can change ownership during such a move.
The winner is the player who ends up owning all the cubes.
You can use settings to select board size, computer players, move animations and players' colors. Each computer player can have its own style and skill level. If not playing, it can provide hints to the corresponding human player. You can also pit one computer player against another and watch the outcome. See the Game Configuration section for more details.
