Tips for a better score
- The wait before green is random, anywhere from about one to three and a half seconds, so don't count in your head. Stay loose and react.
- A false start is logged as 600 ms and a missed round as 1,500, so a slow honest tap almost always scores better than a lucky guess.
- Every round waits for you: tap once to arm it, then the circle turns green somewhere between about one and three and a half seconds later.
- Your press counts the instant it lands, not when you let go, so rest a finger on Space. Only Space, Enter, the A button and a tap count.
About Reflex
Reflex measures your reaction time over five rounds. The circle turns red while you wait, then green without warning; tap the instant it changes. Tapping early counts as a false start. Your score rewards a fast average and your single best round.
