About this test
Numbered tiles flash on a grid, then the numbers disappear. Tap them in order from memory — lowest to highest. Each round you clear adds another tile. Three mistakes and the game is over. How far can you climb?

Frequently asked
How does the Chimp Test work?
Numbered tiles appear on a grid. The moment you tap the lowest number, the rest hide — and you have to tap the remaining tiles in ascending order from memory. Clear a round and the next one adds a tile. Three mistakes end the game; your score is the most tiles you cleared in one round.
What is a good score?
Most people clear somewhere between 7 and 9 tiles. Getting past 12 is genuinely strong, and clearing the full board is rare. Famously, chimpanzees trained on this task can outperform most humans — that's where the name comes from.
Is this a memory or IQ test?
It's a game that measures one narrow skill — visual working memory for number positions — under pressure. It is not an IQ test or a clinical memory assessment, and it says nothing about your intelligence. Treat the score as a game, not a verdict.
How does the leaderboard work?
The most tiles you clear in one round is recorded on a leaderboard. The weekly board resets every Monday (UTC); the all-time board never resets. Impossible scores are auto-rejected.
