NeurooHow many digits can you remember?
See a number. Memorize it. Type it back. Every round adds a digit — most people top out around 7. One miss and it's over.
You'll start with 3 digits. The number disappears — then it's on you.

This is a classic digit span test — how many digits you can hold in short-term memory at once. Research going back to the 1950s puts the typical span around 7 ± 2 items for most adults. Chunking (grouping digits the way you group phone numbers) is the main trick for pushing past it.
Can you improve it?
Digit span responds to practice — especially to learning chunking strategies and training consistently. That's exactly how Neuroo's Number Memory game works: it starts easy, adds a digit each level, tracks your best, and folds into a 3-minute daily plan alongside 14 other memory, focus, logic and reasoning games.
