Shamrocks Solitaire

This app is fun if you like brain teasers. It isn’t based purely on luck like some other solitaires, but requires strategy. The scoring system is completely mysterious. Sometimes you get a high score on an easy-to-solve game and other times you spend double time on a tricky one and get a lower score even if you win. Also, you often see two scores, and there’s no way to figure out which is the one being added to your cumulative average.
