How to play
Numbers are scattered across a grid. Press 1, then 2, then 3 and so on until the last number. The timer starts with your first press. A wrong press adds a one-second penalty.
Difficulty
- Easy: 1–9 (3×3)
- Normal: 1–16 (4×4)
- Hard: 1–25 (5×5)
Tips
- Keep your eyes moving ahead: look for the next number while your finger presses the current one.
- Use peripheral vision rather than scanning row by row.
Fair layouts
Every tile is large enough for comfortable touch. The daily layout is generated from the UTC date, so everyone gets the same grid.
