l like chess,and it is fun to play chess in this app,it has hints so we could use them if we stuck in a game.I like how this app has challenges in like one move checkmate,two move checkmate and three move checkmate and this app helps you to be smart thinker and each day I get better in chess and this app's graphics,controls and ideas are awesome I just love this app.I am a better chess player now after playing chess in this app.
