In this fast and colorful game of visual perception players slide rows or columns of balls in an effort to align together two or more balls of the same color. The balls that were aligned are collected and count towards the player’s score.
On their turn, each player selects a row or a column of balls (a line) and pushes the entire line of balls. The movement must stop when if continued a ball will fall off the board. In the process of pushing existing gaps between balls on the row or column are eliminated.
The result of a push must be that at least two balls of the same color must end up adjacent to each other (horizontally or vertically). The player then collects all balls of the same color that because of the move became adjacent to each other and places them in their tray.
