The game takes place on a square field of 9 × 9 cells and is a series of moves. Each turn, the computer first puts three balls of random colors into random cells, the last of which is only 7. Next, the player makes a move. He can move any ball into another free cell, but there must be a path from free cells between the initial and final cells. If after moving it turns out that five balls of the same color are collected in a horizontal, vertical and diagonal line, then all such balls (of which there may be more than 5) disappear and the player is given the opportunity to make another movement of the ball. If after moving the line it does not line up, then the move ends and a new one begins with the advent of new balls. If a line is collected when new balls appear, then it disappears, the player receives points, but no additional movement is given. The game continues until the entire field is filled with balls and the player can not make a move.
The goal of the game is to score maximum points. The account is arranged in such a way that when removing more balls than 5 in one move, the player receives significantly more points. During the game, the screen shows three colors of balls that will be thrown onto the field the next turn.
In custom mode, you can change the size of the field, the number of appearing balls, the length of the disappearing line, and the amount of color.
