⚡ Play Reflex online
Reflex online means real opponents, not scripted bots: blocks.pw matches you against actual humans (or the friends you personally intend to humiliate), and every round of pure reaction time is scored live. All of it runs in the browser tab you already have open.
How online play works
Two ways in. Quick match pairs you with opponents from around the world — play your rounds, the server settles the score, your ELO moves. Or create a challenge link: you play first, send the link anywhere, and the duel completes whenever your opponent plays their half. No lobby, no waiting room, no "friend request pending".
The async format is the quiet superpower: online doesn't mean simultaneously online. Your opponent can be eight time zones away and the duel still works.
Is online Reflex fair with lag?
Yes — because nothing you do waits for the network. Your pure reaction time is measured on your own device, then results are compared server-side. A spotty connection can delay the scoreboard, but it can't slow your block, eat your tap or fake your time. Ping is not an excuse here, which some players find liberating and others find deeply inconvenient.
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.
