The playing field consists of cells in which balls lie. You need to make lines of 5 or more balls of the same color horizontally, vertically or diagonally.
The composed line disappears from the field, which brings the player points.
To move a ball from one cell to another, it is necessary to have a path free of other balls. This path should consist of empty cells. Moreover, the ball can only go horizontally or vertically, there is no diagonal passage!
If, after a move, not a single line has formed on the field ready to be deleted, three balls of arbitrary color appear in random three empty cells of the table. Their colors (but not positions) are shown in the tooltip at the top of the field.
The game ends when all the cells of the field are occupied by balls.
Good luck in the game!
