How CubeArena works

  • Same scramble
    You and your opponent get the exact same WCA scramble at the same moment.
  • Synced start
    A shared 3-2-1 countdown starts you both together — no head start for either side.
  • First to solve wins
    Race the 3x3 on a real 3D cube; the server times both solves and names the winner.

Frequently asked questions

Is CubeArena free?

Yes. CubeArena is completely free — no account, no signup, and no download. You play a real 3D Rubik's Cube in your browser and can race others instantly.

Do I need a physical Rubik's Cube?

No. CubeArena is a real interactive 3D cube you solve on screen — drag to twist on a phone, keyboard turns on desktop. No physical cube needed.

Does it work on my phone?

Yes. CubeArena is built for mobile — you drag on the cube to twist it — and works the same on desktop. It runs in the browser with no app to install.

Are the scrambles fair for real cubers?

Yes. Both players race the exact same WCA random-state scramble, generated with cubing.js — the same generator the csTimer speedcubing timer uses — so every race is fair and legitimate.
