How the count the flash test works
Press Start and a cluster of dots flashes on the screen for a fraction of a second, then vanishes. Type how many you saw. Get it right and you move up a level — one more dot, a shorter flash. Get it wrong and the run ends. Your score is the highest level you reached. It measures subitizing: your brain's ability to know a quantity at a glance, without counting one by one.
What is a good level?
- Level 3 or below — just warming up.
- Level 5 to 7 — a solid, quick eye.
- Level 9 to 12 — fast; you estimate large groups well.
- Level 15+ — exceptional.
Tips to count faster
- See groups, not dots — break the cluster into small chunks of two and three.
- Soften your focus so you take in the whole field at once.
- Trust your first impression — there's no time to recount.

Frequently asked questions
What is subitizing?
Subitizing is instantly recognising how many objects are in a small group without counting them one by one. This test pushes that skill by flashing more dots for less time each level.
How is Count the Flash scored?
By the highest level you reach. Each level adds a dot and shortens the flash, and one wrong answer ends the run.
What is a good score?
Reaching level 5 to 7 is solid, level 9 to 12 is fast, and level 15 or higher is exceptional.
Does it work on a phone?
Yes. Watch the flash, then tap the answer box to type how many dots you saw.
