Ratings and Reviews

Don’t buy this one

Frog walk

Ponderous and slow. No smooth motion. Hesitant. Primitive graphic interface.

Do Not Purchase


This chess app is rotten to the core. So many flaws I don’t know where to begin. Lets see…does not allow pawn promotion in many instances. Allows illegal moves. Pieces change, e.g., a rook suddenly becomes a queen, a queen suddenly becomes a king, etc., etc. Allows moves placing the computers king in check. Game sometimes quits unexpectedly. The stated levels of play, “Novice, Average, Expert, Senior Master, Grandmaster” are bogus, especially what is called “Novice.” I gave the game one star only because there is not an option for “no” stars. Save your money. “DO NOT PURCHASE” this app.

Great Computer Player AI

Super Enigma

The app is very good overall, I like the included chess books, but more importantly is has the BEST artificial intelligent computer player of any chess app I’ve ever used!
