Exercise Your Brain! This is the unlimited, ad-free, version of the hit brain training app. Mind Games is a great collection of games based in part on principles derived from cognitive tasks to help you practice different mental skills. This app includes all of Mindware’s brain exercising games. All games include your score history and graphs of your progress. The main app shows a summary of your best games and today’s scores on all games. Using some principles of standardized testing, your scores are also converted to a comparison scale so that you can see where you need work and excel. The Training Center selects games for you to play in order to maximize your progress and enjoyment.
