About this tool
The Number Memory Test shows you a number for a short moment and then hides it.
Your job is to type the number from memory using the keypad built right into the game, so you never need to open your phone keyboard. The first round has three digits.
Each correct answer adds one more digit and gives you a little more time to look, which is one second plus about 0.6 seconds for every digit. One wrong answer ends the run and shows you the correct number.
Your score is the longest number you typed correctly, from 1 to 40 digits. A popular trick is to split long numbers into small groups of two or three digits, like a phone number, and say them quietly in your head.
Your best score stays in your browser only. After each run you can post it to this week's TOP 10 with a nickname (not your real name), and send a challenge link so a friend can try to beat your record.
ⓘ This game is just for fun and is not a medical or intelligence test; results vary with your device, mood and sleep.
How to use
- Press Start and look at the number before it disappears.
- Type the number on the keypad and press the check button.
- Keep going until you miss, then post your digits and challenge a friend.
