The basic idea of the game is to create bunches of like-colored balls. This is achieved by swapping adjacent balls with each other (not diagonally). The bigger the bunch the more points that bunch is worth. However, not every ball can be swapped with the one next to it. A valid swap is achieved by clicking with your mouse when at least one of the two balls that are swapped have a ball of the same color next to it in its new position (diagonal swaps are not allowed). You can lose points for invalid swaps in some game modes. For faster swapping try dragging balls!
