Chimp Challenge

The numbers vanish. The order stays.

Small rules. Big focus.

1. Start with 4 numbers among 40 positions. Select the numbers from 1 through the current level in order. There is no time limit.
2. Numbers stay visible at Level 4. From Level 5, the remaining numbers hide after you select 1.
3. A wrong choice reshuffles the same level. Three consecutive mistakes at one level end the game; passing a level resets all three attempts.
4. Your score is the level reached, from 4 to 40. Higher is better. Completing Level 40 ends the game.
5. Use touch or mouse, or Tab and arrow keys to move focus, then Space or Enter to choose. Leaving for the background interrupts the game.

No sign-up. Just a little play.
