SmartPref is a fun, addictive, and extremely challenging game for Android devices. In this game, you will be given a choice of two opposing players and will have to determine who will win. 

Each player will be given their own set of options and moves, and the winner will be the one who is the most skilled. You can even hire a cheater to aid you in your match, but this is only an option for players who want to do whatever it takes to win — even if it means deviating from the moral norm.
