(Thanks to all the people that have downloaded my app Brain training chess and have given me positive feedback!)
I want to recommend my app for you guys, it is called: Brain training chess, It is a chess working memory game for iphone/ipad etc, designed to increase IQ and chess skill. There is now a free version available which offers all 4 levels! The free version is called The brain training chess. The pay version is called Brain training chess and costs only 2,99 dollars.
If you can get a perfect score on level 4 three times in a row whilst playing the free version of the app you win 50 dollars! (You have to make an uncut recording yourself whilst playing and send it to me before you get the money).
