How to play
Get started in a minute
- Some numbers appear scattered across the grid — on the first level, 1 through 3.
- Memorize the positions and tap 1. At that moment, all the other numbers get covered.
- Keep tapping the cells in ascending order (2, 3, 4…), from memory.
- Got them all? You move up a level and the next grid gets one more digit.
- Tapped the wrong cell? The run ends, the numbers are revealed and you start over from level 1.
Controls by input type
- Mouse/touch: tap the grid cells directly.
- Keyboard: use Tab to move through the cells and Enter or Space to tap. Every hit and miss is announced in text for screen readers.
Tips
- Before tapping 1, trace a mental path linking the numbers in order — memorizing the route is easier than memorizing loose cells.
- Group the numbers in pairs or threes ("2 and 3 at the top, 4 at the bottom"): working memory holds small chunks better.
- Don't rush before the first tap: the clock only works against you once the grid gets covered.

The format is inspired by classic working-memory tests used in cognition research, in which digits are memorized in sequence with a short exposure time. Here it appears as a game, with no diagnostic claims whatsoever.
Skill. The positions are random, but the result depends only on your short-term memory, which improves with practice. There is no betting, prize or money involved.
Yes. Use Tab to move through the grid cells and Enter or Space to tap a cell. Every hit and miss is announced in text for screen readers.
