How to play
Select connected balls of the same color. A group needs at least two balls.
After a move, balls fall down and empty columns move left. Larger groups score more. Try to clear the board while building the best score you can.
On touch screens, tap once to select a group, then tap anywhere in that selected group to remove it. Tapping another group changes the selection.
Use arrow keys to move around the board. Enter or Space previews a group; press again to remove it.
