A classic game from the 90s where you line up balls. After each move three new balls appear on the board unless a line was just formed, so keep the board clear for as long as you can. Balls are removed when a line of five or more balls of the same colour is formed. To move a ball, click on it, then click the empty cell you want to move it to. There must be a path of empty cells from the current position of the ball to the desired destination. A ball cannot pass through other balls or move diagonally.
