The game is over when the board gets full. @Move balls You can move one ball per turn by one click on the tile followed by another click on the desired destination. A ball can be moved to any vacant spot reachable along a clear path (a chain of horizontally or vertically adjacent empty cells from the tile to the target). @Scores Try to create lines of at least five same-colored balls horizontally, vertically, or diagonally. When lines are formed, balls in the lines immediately disappear from the board, and you get 10+ points along with another opportunity to move a ball. Automatically formed lines will also be removed, though they do not contribute to your score.
