Click the "Connect Cube" button in the sidebar (or the cube icon on mobile). Your browser will show a Bluetooth pairing dialog — select your GAN cube from the list and click "Pair". Make sure Bluetooth is enabled on your device and the cube is turned on (give it a twist to wake it up).

SupaKewber supports most GAN smart cubes that use Bluetooth, including the GAN 356i, GAN 356i Carry, GAN 12 UI, and GAN iCarry. We use a community Bluetooth protocol library, so newer models should work too — but some may need a firmware update.

Bluetooth cube connections can be finicky — here are some things to try:

• Refresh the page and try connecting again. This fixes most issues.
• Move the cube closer to your device — Bluetooth range is limited.
• Make sure only one tab is trying to connect. Two tabs fighting over the same cube will cause problems.
• Close the GAN Robot / CubeStation app if it's open — it may be holding the Bluetooth connection.
• Restart Bluetooth on your device (toggle it off and on).
• Try Chrome or Edge — Web Bluetooth works best on Chromium-based browsers. Safari and Firefox don't support it.
• On Android, make sure "Location Services" is enabled — Android requires it for Bluetooth scanning (we don't track your location).

If it still won't connect, try removing the cube from your OS Bluetooth pairings list and re-pairing from scratch.

Sometimes the Bluetooth handshake completes but the encrypted data channel hasn't fully synced. Try:

• Disconnect and reconnect from the sidebar.
• Do a few random moves — the first 2-3 turns after connecting can sometimes be missed while the encryption keys sync.
• If the 3D cube on screen shows the wrong state, solve the real cube to the solved position and it should auto-correct.

Unfortunately, Safari does not support Web Bluetooth, so smart cube connection won't work on iPhones or iPads. You can still use SupaKewber as a manual timer with the spacebar or on-screen button. For smart cube features, use a laptop/desktop with Chrome or Edge, or an Android device.

Currently SupaKewber only supports GAN smart cubes via the GAN Bluetooth protocol. We'd love to add support for other brands (Moyu, QiYi, etc.) in the future — let us know if that's something you'd like!

If you have a smart cube connected, the timer starts automatically when you make your first move after a scramble, and stops when the cube is solved. No buttons needed!

Without a smart cube, press and hold spacebar (or tap the timer area on mobile) to prime the timer, then release to start. Press again to stop.

CFOP is the most popular speedcubing method. When using a smart cube, SupaKewber automatically detects each stage of your solve and gives you split times:

• Cross — Solving the first layer cross
• F2L — First Two Layers (corner-edge pairs)
• OLL — Orientation of the Last Layer
• PLL — Permutation of the Last Layer

This helps you identify which part of your solve needs the most improvement.

Scrambles are randomly generated move sequences that put the cube into a random state. Our scrambles use the same WCA-standard random state algorithm used in official competitions, generated via the cubing.js library.

There are three tournament types: Daily (Ao5 solves), Weekly (Ao10 solves), and Monthly (Ao20 solves). You use a trophy ticket to enter — complete all your solves and your average time is ranked against other competitors. Prizes in trophies are awarded to the top finishers!

Trophies are the in-site currency. You earn them by placing in tournaments and they come in two types: 🥇 Gold and 💎 Diamond (worth 10 gold each). You can spend them in the Trophy Shop on tournament entry tickets, avatar frames, and other cosmetics.

Yes! You can use manual timing (spacebar or tap) for tournaments. However, smart cube users have the advantage of automatic detection — no accidental early/late stops.

Yes — 100% free! No paywalls, no premium tiers. If you'd like to help keep the servers running, we have a donate button on the home page.

You can use the timer and practice without logging in. But you'll need an account to save your solve history, appear on the leaderboard, enter tournaments, and earn trophies.

Your solve times and account info are stored on our servers. We don't sell your data to third parties. Passwords are hashed and never stored in plain text.

We'd love to hear from you! Use the contact form below to send us a message and we'll look into it.
