Very good but lacks
The simplicity of this app is perfect. But I need an upgrade to remove adds and make available for use OFFLINE! The move by Apple and Amazon and others to make our apps only available online is unacceptable and anti-freedom. We pay for these apps and we want their use with total freedom. Down with these companies who want to keep us enslaved.

Why?
You have to log into Annoying Game Center to use this app! WHY? Don’t impose this ! So this app is totally useless to me!
Best app i could find!
Great for colour training, i just wish they would add some more games! Like yes/no if two squares are connected by a bishop - or by a knight etc
