Doesn't works – Free Chess Games Review

En passent doesn't work correctly. It lets you make the move but doesn't take the opponents pawn. So far, I've tried two chess apps and both had serious flaws. Also, this app crashed on me when I bumped one of my pieces when it was the computers turn. It moved my piece and crashed when i tried to undo the move. Good competition but can anyone make a chess app that works?
