CubeArena

CubeArena is real-time 1v1 speedcubing in your browser. You and your opponent get the same scramble at the same time — first to solve the 3x3 wins.

How it works

• You and one opponent are handed the identical scramble.

• The timer starts and you both race the same cube, head-to-head.

• First to solve wins. That's it.

Features

• A real 3D cube, not a picture of one — twist it and it moves.

• Touch + full keyboard controls — drag-to-twist on mobile; on desktop, U/D/L/R/F/B turns plus whole-cube x/y/z rotations, and rebindable keys.

• Scramble + speed timer — monospace, running green while you solve.

• Random matchmaking or a private invite code — race a stranger, or send a code to a friend.

• Instant rematch after a race.

• Shareable result card when you win.

• Free, no signup, no download — it runs in the browser.

For cubers

Scrambles are genuine WCA random-state, generated with cubing.js — the same generator csTimer uses. If the scramble quality, notation, or timer feels off, I want to hear it.

Playing a friend

It's real-time 1v1, so you need someone on the other side. Hit "Create a challenge", share the invite code, and they join from their own device. For a quick game, "Find opponent" drops you into a random race.

One-person project

Built by a solo dev and it's early. I'm putting it here to see if cubers actually want to race like this. Tell me what felt good and what felt wrong.

Grab someone, share a code, and race.
