A crystal grows from below, one colored shard at a time. Swipe a line to cleave straight through it.
Any piece your cut isolates that is all one color shatters for score — bigger pure lobes pay far more. But let the crystal crest the ceiling and it's over.

Swipe to cut the crystal in a straight line. A severed piece that is pure (one color, 4+ cells) shatters for score — and one clean diagonal can lop off several pure lobes at once for a combo. Grow a region big before you cleave it: the gamble pays, but the chamber is always filling.
