How to prepare for the Digit Span game (2026)
Digit Span measures short-term and working memory — your ability to hold a sequence in mind and reproduce it accurately.
Practise Digit Span free →What it measures
Working-memory span: how much you can hold and recall correctly under time pressure. It's one of the most reliable, trainable cognitive skills.
How it works
A sequence of numbers or letters (never mixed within one round) appears — sometimes one item at a time, sometimes in groups, sometimes all at once — then disappears. You type it back on a keypad. Sequences get longer as you succeed, and at higher levels you must enter them in reverse order, which is much harder.
Strategies that work
- Chunk the sequence into groups of 2–3 (e.g. 4 8 1 5 → "48" "15").
- Rehearse silently as items appear; keep an inner voice going.
- For reverse rounds, picture the sequence written down and read it back-to-front.
- Don't panic on letters — treat them exactly like digits and chunk them too.
- Practise daily: span genuinely increases with training.
💡 On Prepwise, Digit Span mirrors the real flow — numbers-only or letters-only rounds, the locked keypad while the sequence plays, and reverse recall at higher levels — plus a focus drill if reverse recall is your weak spot.
Common mistakes
- Trying to memorise as one long string instead of chunks.
- Freezing on reverse rounds.
- Rushing the input and mistyping.
FAQ
Numbers or letters?
Both appear, but never mixed in the same round. The keypad shows only that type.
Can I improve my memory span?
Yes — short-term memory responds well to focused practice.
