🧠 Digit Span Challenge
The Digit Span test is a classic cognitive challenge used by psychologists to measure working memory. You’ll see a sequence of numbers appear — then type it back in order (or backward mode for extra difficulty). Each correct recall increases your span length by one. How far can you go before your memory slips?
How to Play
- Click Start to begin. A number sequence will flash briefly.
- After it disappears, type it back in the same order (Forward mode).
- Or choose Backward mode to type the sequence in reverse order.
- Each correct recall increases the sequence length by one digit.
- One mistake resets the test. See how long your span can grow!
