Brain games as unique as you are! When it comes to brain games, one size does not fit all. Each Acuity Games app uniquely adapts to your individual skills and preferences. Games can be as easy or difficult as you choose. They can last just seconds, or have no time limit at all. Your game. Your way. The perfect challenge is just waiting to be played.

Our innovative Lifetime Brain Fitness Measurement is also uniquely your own. Instead of ranking you against other players, we compare your daily, monthly and yearly performance against your average performance. It's incredibly easy to see whether your brain fitness is improving or declining.
