My kids are crazy about DragonBox and Elements, and they wanted to join the chess club at their school and asked for this game. I like that it incrementally introduces the aspects of chess and the beginnings of the game. I also like the tips cards that go along with the game. It's a cute little story game that has really helped my boys with their chess game.
The only thing I don't like is that you can't go back and pick up things you might have missed in each world or have the option to replay boards after you capture the king.
