Test your cube
Connect a Bluetooth smart cube (GAN, MoYu, or QiYi) and turn it - the 3D cube below mirrors every move. Use this page to check your cube connects, manage your saved cubes, and set up automatic reconnect.
This browser can't do Web Bluetooth - use Chrome or Edge to connect a real cube.

Set up automatic reconnect
Smart cube support relies on two experimental Chrome flags - one is required just to connect, the other lets the browser remember your cube so it reconnects without the chooser pop-up on every visit.
1. Use Chrome or Edge on desktop
Web Bluetooth is only available in Chromium-based desktop browsers (Chrome, Edge, Brave, Opera). It is not available in Safari or Firefox, or in any browser on iOS.
2. Enable two Chrome flags
Paste each address into your browser's address bar (links to chrome:// pages can't be clicked), set it to Enabled, then relaunch the browser when prompted.
chrome://flags/#enable-experimental-web-platform-featuresSet “Experimental Web Platform features” to Enabled. Required - without this the smart cube won't connect at all. It also turns on the getDevices() API used to find your previously-paired cube.
chrome://flags/#enable-web-bluetooth-new-permissions-backendSet “Use the new permissions backend for Web Bluetooth” to Enabled. Lets the browser remember your cube across page refreshes, so it reconnects without the chooser pop-up.
3. Connect your cube once
After relaunching, connect your cube above and pick it from the chooser. That one-time grant is what the browser remembers - from then on the trainer reconnects on its own whenever your cube is on and nearby.
