Number Memory guide
A number flashes up, then disappears. Type it back from memory. Each round adds a digit until you miss. See how many digits you can hold at once.
How to play Number Memory
- Starts at 3 digits
- +1 digit a round
- One miss ends the run
Goal
Memorise a number and type it back, as it gets one digit longer each round.
How to play
- A number is shown briefly, then hidden.
- Type it back exactly as it appeared.
- Get it right and the next number is one digit longer.
- One mistake ends the run.
Technique
Digit span is usually about seven digits without help. Chunking beats rehearsal - group the digits into pairs or triples and remember four chunks rather than eleven digits, and pairs that already mean something to you, like a year, cost almost nothing to hold.
Scoring
- Your score is the length of the longest number you recalled correctly.
- There is no time pressure once the number is hidden.
