Great app: you get different: difficulty levels (amateur or advanced games), playing modes (bot, online or with a friend), chessboard designs (bought with game coins), quick challenges to improve your game strategy One, big complaint tho. I really don't like that the game points out when the king is being attacked, you can't even move pawns that protect him. It's annoying as it helps your opponent handle/notice your attacks and because you need to learn to notice those things on your own.
