Goal: pop groups of matching marbles until none are left. Popping: tap a group of 2 or more same-colour marbles touching up, down, left
or right ā diagonals don't count. The whole group pops. A marble with no same-colour
neighbour can't be popped. Scoring: a group of n marbles is worth n Ć (nā1) points ā a pair is 2, five is
20, ten is 90, so big groups pay off fast. Hover a group on a PC to see its points before
you commit. Clear the whole board and add a 1000-point bonus. After a pop: marbles above fall down to fill the gaps, and empty columns close up
to the left. Undo: takes back your last pop. Hint: shows the biggest group on the board. Posting: finish a game with 2,500 or more and you can post your score.
