How people play
Played as a brain gym or a cruel friend challenge. Reaching 10 successful clears feels like leveling up your RAM.
Common challenges
- Passive watching Seeing the flash without chunking it into pairs or rhythms.
- Rush inputs Starting the repeat before the sequence finishes in your head.
- Error spiral One miss shakes you into three more.
What strong play proves

- Sustained focus Short matches still punish zoning out for a single beat.
- Composure Mistakes happen — recovering cleanly is the real skill.
- Decision speed Good enough now beats perfect too late.
