The tempo is set according to your performance, as well as the size of the grids, and the speed automatically and gradually increases with your performance to help you train efficiently. You can also modify the tempo in real-time with ARROWS keys. You can always get better, up to 750 BPM if you can! The rounds are 20 minutes long and at the end, you can see you performance results. # Supported keyboards The target keyboard layouts are the US (QWERTY) and the German (QWERTZ), but 91 variations of these 2 layouts also work for this game.
