MatchBack
Does this card match the one N turns back?
MatchBack is a card-matching memory challenge in the n-back family. You preview a few cards, then for every new card you decide whether it shares a property — shape, fill, border or letter — with the card from N turns back. It trains rolling, always-updating recall — keeping track of what just happened on the table.
How to play
- Preview the opening cards, then press Ready to start the timer.
- For each new card, compare it with the card N turns back.
- Shares at least one active property → 'Some Match'; otherwise 'No Match'.
- Higher N and more properties (shape, fill, border, letter) make it harder.
What it trains

Improvement figures are observed in-app score gains, backed by peer-reviewed cognitive-training research.
Difficulty
Push N deeper and switch on more properties to compare — both raise the load on working memory.
