Can you beat a chimpanzee at a memory test?
A chimpanzee named Ayumu amazed researchers by remembering numbers flashed on a screen for just a fraction of a second. ChimpChamp brings that famous chimp test to your phone, with a challenge you can train for.
See the numbers. Remember their positions. Tap the hidden squares in order.
Easy to learn. Hard to master. Even harder to put down.
HOW TO PLAY
Numbers appear at random positions on the board. Memorize them before they disappear, then tap their locations in ascending order. As you progress, you'll face more numbers and less time to remember them.
Every round is a new test of your visual memory, concentration and recall.
TRAIN YOUR MEMORY
Start with beginner-friendly challenges and work toward faster, tougher memory tests.
• Training Mode: Progress through increasingly difficult stages.
• No-Timer Practice: Learn the board and develop your own strategy without the countdown.
• Beat the Chimp: Put your skills to the test in chimp-inspired benchmark challenges.
Whether you're trying a number memory game for the first time or chasing a personal best, there's always another level to conquer.
