Wurfel vs Cube Solver AI

Wurfel reads your scrambled cube with the camera, then does one of two things: it solves the cube for you, move by move in 3D, or it teaches you to solve it yourself. It works with the 2x2, the classic 3x3 and the 4x4. Hold up each of the six faces and Wurfel fills in the colors. Prefer to do it by hand? Pick a color and tap it onto the stickers of a 3D cube you can spin any way you like. LEARN TO SOLVE IT YOURSELF Always wanted to know how to solve a cube on your own? Learn to solve teaches you the beginner method, step by step, on your real cube. You build it layer by layer, in small chapters, and a short intro shows how it all works the first time. After that, every piece takes three steps: • Find: the piece has a white frame on screen, so you can spot it on your cube • Watch: the cube on screen turns it into place, and the view swings around so you see both the piece and its spot. Pause, step back and forth, or replay them • Do: make the same turns on your cube After each chapter, you check that your cube matches the screen. If it doesn't, nothing is lost: turn the chapter back, or rescan and pick up where you left off. The steps are written so a child can follow them. No cube with you? Scramble one on screen and practice there. OR JUST SOLVE IT Tap Solve and Wurfel works out a short solution, about 20 turns for a 3x3. Every move plays out on the 3D cube and is named in plain words, like "Right clockwise." Play it all the way through, or step forward and back at your own pace. YOUR OWN CUBE'S COLORS Are your cube's shades a little different? Set its real colors in Own cube with the color picker, or let the camera read them off your solved cube, one face at a time. The scanner and the guide then use your cube's colors and their names. High contrast and Color-blind palettes are built in, too. WHAT YOU CAN DO • Scan and solve the 2x2, 3x3 and 4x4 • Scan with the camera, face by face, or enter the colors by hand • Learn to solve it yourself with the beginner method, one piece at a time • Watch every move in 3D, with each turn spelled out in words • Color checks catch a wrong sticker before you solve • Switch between solving and Learn to solve with one button on the home screen WORKS ANYWHERE • Fully offline, even with no signal • iPhone, iPad and iPhone Duo, in light or dark mode • Choose a light, dark or automatic app icon • No account, no ads, no subscription, no tracking TRY IT, THEN PAY ONCE Wurfel is free to download, and your first two solves are on us, with everything included: camera scan, 3D playback, every cube size. Solving the same cube again never uses up another solve. A guided solve in Learn to solve counts as one of the two. After that, a single purchase unlocks everything for good. No subscription, no ads, no second bill.

Completely free. No in-app purchases, no subscription, no paid tier, no account — every feature described below is simply there when you open the app. Point your camera at each face and Cube Solver AI reads the colours for you, then walks you through the solution one turn at a time, with the layer actually rotating on screen. SCAN WITH YOUR CAMERA A neural network trained for colour constancy runs entirely on your device, so it copes with warm lamps, cold daylight, and the glare that makes white and yellow look alike. A live overlay shows exactly which colour it reads on every sticker while you hold the cube, so you can see it working before you commit. FIX ANYTHING IT GETS WRONG Detection is never perfect on every cube in every light. Tap any sticker on the 3D cube or the flat net to repaint it, with undo and redo throughout. Stickers the model was unsure about are highlighted, so you know where to look first. SOLUTIONS YOU CAN ACTUALLY FOLLOW Every step names the move, describes it in plain words, and animates the layer swinging on the cube, which is far more useful than a line of notation. Step back and forth freely, jump to any move, or hand it to auto-solve and just watch the cube unscramble itself. Choose slow, normal or fast, and let the camera follow the turning face or stay put. 3x3, 4x4 AND 5x5 The 3x3 uses a two-phase search that finds solutions of around 20 moves. Larger cubes are solved by reduction: centres first, then edge pairing, then the 3x3 finish, including the parity cases that only appear on even cubes. FREE, PRIVATE, OFFLINE The neural network and the solver both run on your iPhone, so your photos never leave the device and nothing is collected about you. It works with no signal at all.
