⚡ Reflex
Tap the block the instant it turns green. Reflex tests pure reaction time — free in your browser, no download, no signup. Reflex appears as one of the nine mini-games in a blocks.pw duel: best of 5 rounds against a real opponent, 30–40 seconds total, in your browser.
How to play Reflex
- A block appears red. Both players wait — fingers hovering, nerves fraying.
- After a randomised delay it snaps to green. Tap immediately.
- Your time is measured in milliseconds from the colour change to your tap.
- Tap while it's still red and you forfeit the round — anticipation is the cardinal sin.
Rules and scoring
The faster tap wins the round; duels run best of 5 across a shuffled set of mini-games. Your millisecond time shows after every Reflex round, so you always know exactly how fast (or tragic) you were.
The randomised delay is the whole game: it's long enough that you can't rhythm-guess it and short enough that your attention can't wander. Every round is a fresh coin-flip between your patience and your twitch.
Strategy: how to win at Reflex
- Watch the block, not your finger. Attention on the stimulus is reliably worth 10–20 ms.
- Rest your fingertip on the screen (or keep the mouse button half-committed) — travel distance is wasted time.
- Don't predict. The delay is random precisely to bait early taps; a forfeited round costs more than a slow one.
- Warm up with two casual rounds first — cold reflexes run 20–30 ms slower.
Where Reflex fits
In a duel, Reflex rounds arrive shuffled among the other mini-games — Reflex, Smash, Stack and the rest — so winning the match means being dangerous at more than one skill. Start a quick match against the world or send a challenge link to someone who deserves humbling.
