After reading other reviews of the game about some potential cheating going on, I am sad to say I will be deleting the app.

I scoured the Internet to validate the legality of that move and couldn't find it anywhere, leaving the only conclusion to be that the computer in the game is somehow allowed to cheat. I thought was a glitch so I undid my move (the undo button is helpful for learners as well) and tried to redo it. The game allowed a knight to move diagonally one square to take my rook that I used to take a piece and put its King in check. At first I thought it was just glitchy or that it knew rules that I didn't know. Sadly, as I was able to move up to much higher difficulty levels, it wouldn't allow me to make some legal moves and it was able to make illegal moves. When I first was learning chess it was terrific and I was able to fine-tune my skills with the difficulty changer setting. I have been playing on this app for a few years almost DAILY when time allows. If you are a beginner that knows how to play then this app is great for you! But other than that 10/10 would recommend! If you completely new to this game and don’t know how to play it can be hard to get the hang of it on this app. There are no adds during game time which is really great! However the one thing that is a little frustrating is that you have to have your volume up to know that your in cheek of you don’t see it and that it is hard to tell when it is your turn. If you want a fun game to test your logic skills and challenge your brain you should definitely download this app now!if you need to practice chess for aCompetition this is perfect for you because you can have it at any difficulty and can undo your moves so you can learn from them. It’s really great how you are playing against a computer and not real people for safety. I love how you can start over the match, set the difficulty, and make new games very easily. This game is straight up chess you can do lay from anywhere at any time.
