Find the Number

One digit hides in the noise. The grid grows, the clock shrinks.

How to play
  1. 1

    The prompt names one digit — find it in the grid.

  2. 2

    Only one cell holds it. Tap it before the bar runs out.

  3. 3

    Each round the grid grows and the timer gets shorter. Three misses and you're out.

WHY IT WORKS

Why it works

This is visual search, the task used to study how attention sweeps a cluttered scene. Because every distractor is also a digit, nothing pops out on its own — you have to scan deliberately. Skilled searchers stop reading each cell and start letting the target shape surface on its own.

FAQ

What round is good?

Round 7 is solid, round 10 is sharp. The grid is 9×9 by then and you get four seconds.

What's the trick?

Sweep row by row at a steady pace instead of jumping around. Most people lose time re-checking cells they already passed.
