Can two people play on one phone?

The duel format uses one device per player facing identical rounds — fairer than shared-screen. In the same room, just pass the challenge link between phones.

Does 2-player mode cost anything?

Nothing — duels, links and rematches are all free, no accounts required on either side.

Can we play from different countries?

Yes — the link works across any distance, and the asynchronous format shrugs at time zones.

⚡ Reflex — 2 player game

Two-player games used to mean one couch and two controllers. Reflex keeps the head-to-head soul and drops the furniture requirement: each player on their own device — same room or different continents — facing the identical challenge, with pure reaction time deciding it.

Two devices, one duel

Player one opens blocks.pw/new, plays the best-of-5, and sends the link. Player two opens it anywhere and plays the same sequence. The score settles automatically — no console, no accounts, no "pass the phone". Sitting side by side works brilliantly too: create, play, hand over the link via one message, and trash-talk in person while they sweat.

Why same-challenge beats same-screen

Classic two-player games split one screen and one input device unevenly. Here both players get identical conditions — same Reflex rounds, own device, full screen — so the duel measures pure reaction time and nothing else. It's the fairest version of two-player: no player-two controller with the sticky button.

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.
