Complete a Smart Cube solve to start coaching.
Keep this orientation for the whole solve. Smart Coach reads OLL and PLL moves in this frame so it can match the correct algorithm.
Coaching compares your stage shares, consistency, move efficiency, and recent trend. It never invents a case when the move stream is uncertain.
— — OLL recognition scans the move stream across cube rotations; PLL works backward from the solved cube. Earlier attempts and final AUF turns no longer hide the last recognized case.
Check the last result, compare quick session marks, or reuse an earlier scramble.
Build four correctly matched edges on the bottom, then learn to plan the full solution and flow directly into your first F2L pair.
Each white edge has a second color. That side color must line up with its matching center. Keep the completed cross on the D face so the U layer stays free for F2L.
Do not memorize cases. Read where each edge belongs and use the bottom layer as a movable workspace.
Locate a white edge. Read its other sticker—red, orange, blue or green—to identify its destination.
Centers never move relative to one another. Bring the edge toward the center with the matching side color.
Turn D or D' to place the target cross slot under the edge. Move solved edges away before turning through them.
Send the edge to the bottom, restore any temporarily moved layer, and check both stickers—not only white.
The aim is not frantic turning. It is one smooth, remembered sequence with no search pauses.
Begin with the most awkward edge or the move that improves two pieces at once—not simply the first white sticker you notice.
You do not need to keep centers visually aligned after every move. Track the edges relative to one another, then align D at the end.
During practice, rehearse the entire solution once. Then execute it without looking for cross pieces again.
As your hands finish the planned moves, your eyes should already be finding a white corner and its matching edge.
Advanced Cross is mostly better planning: solve pieces together, preserve finger flow, and finish in a useful F2L position.
Build two or three cross edges in the correct relationship even if they are not yet aligned with centers. One final D move can align the whole cross.
If one move inserts an edge while moving another into an easier position, count it as progress on both pieces.
Prefer solutions with comfortable turns and few rotations or regrips. A slightly longer Cross can be faster when it starts cleanly.
Choose whether the last alignment is D, D' or D2 so your first F2L pair faces a comfortable slot.
Once the Cross is fully planned, watch a promising corner or edge during execution instead of staring at solved pieces.
Master one Cross color first. Add another color only when inspection and bottom Cross execution already feel automatic.
An X-cross finishes the normal Cross and one complete F2L pair in its slot. It is powerful when the pieces are convenient, but inefficient when forced.
Look for an already paired corner and edge, pieces close to each other, or a pair whose moves overlap naturally with the Cross.
Know where the pair belongs. Keep that slot available while solving the Cross, or deliberately open and restore it.
Pair or insert the F2L pieces during Cross moves instead of solving a normal Cross and starting the pair afterward.
If the X-cross adds awkward moves, rotations or uncertainty, solve a clean Cross and preserve the easy pair for first.
Use normal scrambles. Accuracy comes first; speed appears when the plan becomes automatic.
Find the full Cross with no time limit. Rehearse it, execute, reset, then find a cleaner solution.

5 successful crossesKeep your chosen orientation and solve on D. Use face and D turns instead of rotating to chase each edge.

Locate a white corner and the edge whose two side colors match it.
Use U moves and a free slot to bring both pieces into a basic insert.
Solve the pair into its slot, then look for the next corner and edge.
The corner and edge are already paired. Align the pair above its matching slot and insert it.

The cross is the first step of CFOP. Your goal is to solve 4 white edge pieces on the bottom layer, aligned with their center colors. A good cross should take 8 moves or less.

Everything you need to know about SupaKewber
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:
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:
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:
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.
