Digit Span is a classic working-memory challenge. Choose forward or backward recall, watch digits appear one by one, then enter them. Correct answers increase length; two misses end the session and report your span.
How to play
- 1Choose Forward or Backward mode.
- 2Watch each digit appear in sequence.
- 3Enter the digits in order (or reverse order for Backward).
- 4Two misses end the run — your span is the longest successful length.
Tips
- • Group digits like a phone number once sequences get long.
- • Backward mode is harder — start forward to warm up.
- • Stay relaxed; tension often causes early mistakes.
