Lean on the legend at first, then trust your memory.
- Tap Start and glance at the digit-to-symbol legend
- A digit appears in the panel
- Tap the matching symbol on the pad below
- Keep going for 60 seconds, racking up correct matches
No sign-up is needed and your best correct count is stored locally on your device.
What it trains
This game blends speed with a touch of memory.
- Processing speed under a time limit
- Working memory as you start to recall the pairings
- Sustained attention across many quick matches
You mostly get faster at this game with practice. Enjoy it as a brisk brain teaser rather than a measure of intelligence.
A tip: memorize a few pairs
You don't have to check the legend every time.
- Memorize two or three pairings to skip lookups
- Glance at the legend only for the ones you forget
- A steady pace beats frantic tapping
- Accuracy counts - wrong taps don't score
The honest way to read your score
Your matches per minute will vary with alertness, so compare only with your own earlier runs and watch the trend over time.
For related practice, try digit span or a working memory test.
