Memory Test

A memory test with three games: remember ever-longer numbers, the order in which squares light up, or the positions of squares that light up together. Use it to test and practise your short-term memory for fun.

How to use

1. Under "Game", choose "Number memory", "Sequence memory" or "Position memory", and press "Start".
2. In number memory, type the number after it disappears and press "Check".
3. In sequence memory, press the squares in the order they lit up. In position memory, press every square that was lit.
4. At the end, "Level reached" appears and is saved under "Best by game". Press "Play again" to try again.

How it works

• Number memory starts with 3 digits and adds one digit after each correct answer. The number is shown for 0.7 seconds per digit. One wrong answer ends the game.
• Sequence memory starts with 2 steps and adds one step per level. After 7 steps the grid grows from 3×3 to 4×4. One wrong press ends the game.
• Position memory starts with 3 squares and adds one square per level. You have 3 lives, and three misses in one level cost a life.
• This is a game for fun and practice, not a medical test or diagnosis. Records are saved in this browser.

Questions and answers

What is working memory?

It is the memory you use to hold information in mind for a short time while you use it, for example while writing down a phone number. All three games ask you to hold what you just saw and repeat it.

How can I remember more digits?

Group the digits into chunks of two or three. For example, remember the 7-digit number 5829316 as 582, 93, 16.

Can this test show whether I have a memory problem?

No. The result is a game score that changes with attention, tiredness and the screen. If you are worried about your memory, talk to a professional.

Can I play with a keyboard?

Yes. Move between squares with the arrow keys and press one with Enter or Space. In number memory, type the digits on the keyboard.
