⚡ Reflex with no download
The app-store ritual — search, download 200 MB, create account, allow notifications, watch tutorial — takes longer than an entire Reflex session. blocks.pw skips the ritual: the page is the game. Tap a link, and you're testing pure reaction time before an app store would have finished asking for permissions.
Why no-download matters more than it sounds
Zero megabytes of storage on a phone that's perpetually full. Zero updates to babysit. Zero "this app is no longer compatible with your device". And the killer feature for a duel game: when you send someone a challenge link, they can accept it immediately — no "download the app first" wall for your opponent to bounce off. Every install step between a challenge and a rematch loses half the challengers.
Instant, but complete
No-download doesn't mean demo: the browser version is the whole game — full Reflex, all nine duel mini-games, solo modes, world and country leaderboards, ELO. It loads light (the whole thing weighs less than one photo), runs on years-old phones, and works the same on the next device you open it from.
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.
