- Keep your streak alive - three wrong answers ends the game
No account is needed and your best streak lives on your device.
What it trains
Counting one color while ignoring the rest is a neat selective-attention workout.
- Selective attention
- Quick mental counting
- Filtering out distracting colors
Be honest: you mainly get better at this counting task, and it is not an IQ measure or a diagnosis.
Tips to keep your streak
Counting cleanly beats counting fast.
- Count in a fixed path, like left to right and down
- Group nearby matching dots in twos and threes
- Double-check before you tap if the choices are close
The honest way to read your score
Your best streak is a personal yardstick, nothing more. It will rise and fall with focus and tiredness, so only measure yourself against your own past runs.
