Press Enter or X to start the game. Use the Arrow Keys or WASD to move your number cube. Connect numbers of the same value to merge them together. Keep going until you reach 32.

When your cube touches another number cube of a different number, you will activate it. All active cubes will move in the same direction you move (unless there is a wall in their way). Number Zero blocks do not have this ability, but you can push them out of the way.

When a number passes through a division symbol, its value will be reduced by half.
