Solitaire Match-3 uses a 3-star system for scoring that is updated as you create matches over the course of a level.
The following rules apply to Scoring:
Each cleared Gem is worth 100 points
Each cleared Obstacle is worth 500 points
Each Special used is worth 1,000 points (combining two specials is worth 2,000 points)
Creating larger matches, cascades, using specials, and finishing with extra moves will net you a higher score!
