Play
Start a game by pressing a Start button.
The number on the button is the number of different colors.
More colors make the game harder.
Click on a touching set of same-colored marbles to obliterate the set.
Only sets of two or more marbles can be obliterated.
To win, all the marbles must be obliterated, with no leftovers.
Scoring
The score for obliterating a connected set of marbles is the square of the
hypotenuse of the number of marbles in the set times the number of different colors
used divided by four. For more help with scoring, see an accountant.
