Digit Span Test
Free forward and backward digit recall
Remember the digits
Recall the digits in the same order.
🎯 How to Play
- Choose Forward or Backward. Watch the digits one at a time, then enter the full sequence with your keyboard or the on-screen keypad. Input is untimed.
- Start at 3 digits. A correct answer advances immediately; after an incorrect answer, retry once with a new sequence at the same length. Two incorrect answers at that length end the test.
- Examples are unscored. Keep the page active while digits appear; an interrupted trial is void and can be restarted.
Leaderboard
Forward and Backward rank separately by longest correctly recalled sequence.
Practice benefits & everyday uses
Short-term memory
Practice holding a short sequence in mind before entering it. You use short-term memory when remembering a verification code, a phone-number fragment or a brief instruction.
Working memory
Backward recall asks you to remember information and change its order at the same time. Working memory also supports mental arithmetic, comparing prices and keeping track of steps in a recipe.
Focused attention
Follow each digit without losing your place. Staying with a stream of information also matters when listening to directions, checking details or copying numbers accurately.
The Science Behind the Game
The science behind digit span practice
A digit span task uses short-term sequence memory: digits appear one at a time and are recalled afterward. Forward recall preserves the original order. Backward recall adds the challenge of holding the sequence in mind while mentally rearranging it.
Try grouping digits and silently rehearsing them. For example, hold a six-digit verification code as two groups of three. Use progressively longer rounds and your attempt review to explore which memory strategies work for you.
Presentation speed, distractions and memory strategies can affect your span. Compare rounds within the same mode and timing rules, and use a quiet setting to make your own results easier to compare.
