Online Rubik's cube timer
A speedcubing timer on your phone or computer: hold Space (or your finger on the screen), let go to start and press again when you finish.
- Official WCA scrambles for every event: 2x2 to 7x7, blindfolded, one-handed, Megaminx, Pyraminx, Skewb, Square-1 and Clock.
- 15-second inspection as in competition, with 8 and 12 second calls and +2 and DNF penalties.
- ao5, ao12 and mo3 averages, your best time, a histogram and your progress. Import your times from csTimer or Twisty Timer.
- With a smart cube (GAN, MoYu, QiYi…) the timer starts when you turn and stops when it is solved, with a breakdown of each CFOP step.
- Free, no ads and no account: your times are saved in your browser and it works offline.

Your cube
Connection
To use your smart cube on iPhone or iPad
- Install Bluefy, a free browser with Bluetooth.
- Open twistlab.app in Bluefy.
- Tap Connect and pick your cube. The first time it may ask for the cube’s MAC; the app remembers it.
Without the cube, everything else (timer, Academy, Quiz) works in Safari.
- Cube
- –
This cube doesn’t report its colors: the app takes it as solved when it connects. If it wasn’t, solve it and tap “Mark as solved” or give the yellow face two full turns in a row.
Connect your smart cube over Bluetooth (Chrome or Edge): GAN, MoYu, QiYi, GiiKER or GoCube. Some ask for their MAC address the first time; after that the app remembers it.
How do I find my cube’s MAC?
Some cubes (GAN, MoYu, QiYi) encrypt their data with their MAC address, and the browser doesn’t always let it be read. Three ways, from the easiest to the most manual:
- Let the app read it by itself (Chrome or Edge, on Windows, Mac or Android): open chrome://flags/#enable-experimental-web-platform-features (in Edge, edge://flags/#enable-experimental-web-platform-features), enable it, restart the browser and connect again.
- See it in the browser (Windows, Linux and Android; on a Mac the address shown is made up and won’t work): open chrome://bluetooth-internals/#devices, press Start Scan with the cube awake and look for its name: the MAC is its address (AA:BB:CC:DD:EE:FF).
- On GAN cubes, the name ends with the MAC’s last two pairs (GANic4_8CA7 → …:8C:A7). When you connect, the app types them into the box for you: you only replace the XX with the other four pairs.
If you enter a wrong MAC, no valid data comes in: the app tells you and asks for it again when you connect.

On your cube
With the white cross down, yellow up and green in front: each pair’s case, with the turn that brings it to the front-right slot, and then the last layer’s, with your algorithm.
Settings
Recalibrate: if the cube on screen doesn’t follow how you hold yours (cubes with a gyroscope). A quick full turn of the white face does it too: four quarter turns the same way, within 2 s.
Mark as solved: if the cube on screen doesn’t match yours, solve it by hand and press this, or give the yellow face two full turns in a row (eight quarter turns the same way, within 4 s).

Guide
I take you move by move: to a random scramble, or to solving the cube from wherever it is.
Paint your cube
No smart cube? Copy your cube’s colors or type its scramble and I’ll tell you how to solve it, move by move.
Rubik's cube solver online
Hold your cube with yellow on top and green in front, and copy its colors onto the net: the cube unfolded, each face next to its neighbors. The centers are already set. To see the top face, tilt the cube toward you; for the bottom, tilt it away.
With a keyboard: arrows to move, 1–6 paints that color, Space paints the selected one.
Solution
How the solver works
- Copy your cube’s colors onto the net, or type the scramble in notation (R U F2…) and I’ll paint it.
- Before solving I check that your cube is possible: too many of a color, pieces that don’t exist, twisted corners or flipped edges.
- Pick the shortest solution, worked out by the computer, or the beginner method, explained step by step.
- Follow every turn on the 3D cube, forward and back, at your own pace.
- Free and ad-free, on your phone or computer.

Frequently asked questions
Is it free?
Yes, completely: no ads, no paid version and no limits.
Do I need an account?
No. You open the site and start: there’s no sign-up. The account is optional and only keeps your progress, to have it on all your devices.
Does it work with my smart cube?
With Bluetooth cubes from GAN, MoYu, QiYi, GiiKER and GoCube, from Chrome or Edge on Android, Windows or macOS (on Linux it may need enabling in chrome://flags): go to Cube and tap Connect. Without a smart cube everything else works (timer, academy and algorithms), and in Paint your cube you copy your cube’s colors to see how to solve it.
And on iPhone?
The site works in Safari, but Safari has no Bluetooth: to connect a smart cube use Bluefy, a free browser that does.
Where is my data stored?
In this browser’s local storage (localStorage). If you clear the browser’s data it’s lost; to keep it or move it to another device, sign in with your email in Progress (it’s saved to your account automatically) or export a backup.
What does the account store?
Only if you sign in with your email: your email, used only to send you the sign-in code (no ads or newsletters), and this app’s progress (times, practice, learning and settings) to have it on your devices. There’s no password; a cookie keeps you signed in for 90 days from your last visit. You can delete the account and everything saved in it in Progress → Account.
Does it work offline?
Yes. After the first visit, TwistLab opens even without internet: scrambles, the timer and the academy work, because everything is computed on your device. You can install it from the browser menu (Add to Home Screen or Install).
Who is it for?
For people who have never solved the cube and for those who want to bring their times down: you start with the white cross and the beginner method, move on to reduced CFOP and get to full CFOP (41 F2L, 57 OLL and 21 PLL cases).
Are the scrambles like the WCA’s?
Yes: random-state scrambles for every event, the same kind as the official ones, generated on your device with cubing.js. They aren’t the ones from a specific competition: those are generated for each competition.
Is it open source?
Yes, under the AGPL-3.0 license: you can see how it is made, suggest improvements or run your own version (under another name). Bugs and ideas are welcome on GitHub.
How can I support TwistLab?
TwistLab is free, ad-free and open source. If it helps you, you can help pay for the server and the database, and keep it growing.
Hold the cube as shown on screen. If you make a mistake, the guide recalculates from where you are.
