Good, but... I give it a 5 for doing what it says it does. Then I subtract 1 because as soon as you make the right move, the trophy cup appears, hiding the board, and it moves to either the next problem or a full screen ad. There is no chance to review your move or the board once you make the right move. Unlike others who say this won't help your game, I think it will because it reinforces checking everything on the board. I subtract 1 more for the in your face ads, but I also give them credit for not interrupting play.
OLD PLAYER Great app to keep the 'chess brain' working when you don't have time to play a whole game. I don't mind the adds because sometimes you might see one that's interesting.
Annoying ads after every second problem Program may be good, but most annoying full page ads after every two problems spoiled it for me. Uninstalling for good.
Performs as described Lots of adds, no other features, does exactly what it says, mate in one puzzles.
Sometimes it has you kill the queen ? No sense at all
Okay but won't really improve your chess.
