Numstone is a speed-focus game with one simple rule: find the numbers in order. Every board is a mosaic of tiles with the numbers scattered across it. Tap 1, then 2, then 3, all the way up. The clock starts on your first tap, and a wrong tap costs you a second. It sounds easy, until you lose your place at 30. If you know Schulte tables, you already know the idea: one board, every number, as fast as your eyes can find them. Numstone turns that classic focus and attention exercise into a game you will want to play every day.
