Developed in close collaboration with cognitive scientists and research universities, NeuroNation’s scientifically validated exercises are designed to improve your memory, focus, and processing speed.

What we love: How genuinely challenging—but very satisfying—these mini-puzzles are. Hone your focus in Color Craze, where you need to quickly identify the word “green,” even though it’s written in blue letters. (It’s much trickier than it sounds.) Or sharpen your pattern recognition by figuring out the next shape in a sequence in Symbol Chain.

Quick tip: Get instant feedback after every game with progress reports that track your growth and show how you compare with your last session.

Meet the creator: NeuroNation was founded in Berlin by Rojahn Ahmadi, Jakob Futorjanski, and Ilya Shabanov in 2011. With backgrounds spanning AI, online gaming, and management, the trio set out to combine cognitive science with gamelike exercises.
