What it trains
The sprint format pushes fast, automatic addition.
- Quick recall of addition facts.
- Visual scanning to spot a partner number.
- Working memory while you hold one value in mind.
Stay honest: you mainly get faster at this game, it is not an IQ measure.
Tips for a bigger score
Speed comes from pattern habits, not panic.
- Anchor on one number and ask what its partner must be.
- Scan left to right so you do not re-check the same tiles.
- If a tile has no partner, move on rather than forcing it.
The honest way to read your score
A sprint score only means something next to your own earlier sprints. Aim to beat last week, not a stranger.
If you enjoy timed number work, try the speed sort game or read about working memory.
⚠ When to talk to a professional
