I havent tried the other S&M app, but this one has choppy animation and slow reaction time (you have to hold your finger on a card for a whole second or two before dragging). No difficulty settings, AI is easy to beat. My GF has played this game her entire life and beats me every time (no kidding, EVERY time)... I need an expert AI to practice against. Theme: what you see is what you get; no choices. Im not a fan. No tutorial for those who want to learn this awesome game. Suggestion: a $0.99 game might hold over a craving for a serious quality S&M app, but if you can wait, do so.
