Try to remove all balls. Any cluster of 2 or more balls can be removed and will add the value indicated. Clusters with more balls have an increasing larger value. The more balls eliminated at once, the higher the points added to the player's score.
The scoring can be expressed in the formula "Y=X(X-1)". X represents the number of balls grouped together, Y is the resulting score. For example an elimination of 16 balls will result in 240 points (240=16(16-1)).
Removed balls will be replaced by moving the columns down. Once a column is empty the space will be filled with the columns to the left of the empty space.
In the standard mode of the game, the game ends when the player has no more moves left; there are no more like-colored balls adjacent to each other.
The player has four unique game styles to choose from, including Standard, which is described above. The other game styles are Continuous, Shifter and MegaShift.
