CommuniCube vs Speed Cube Puzzle

Stuck on a twisty puzzle? Point your iPhone or iPad at it. CommuniCube reads every face with the camera, lets you fix any sticker with a tap, and then walks you through the solution one move at a time on an animated 3D model — in plain English, not just notation. Puzzles it solves (all on your device, no internet needed): - 3×3 Cube — a near-optimal solution of about 20 moves, or the Learn mode that solves YOUR cube with the beginner layer-by-layer method so you understand every stage. - 2×2 Pocket Cube — the shortest possible solution, 11 moves or fewer. - 4×4 and 5×5 cubes — solved step by step by reduction: centres, then edges, then finish like a 3×3, with parity handled for you. - Pyraminx — optimal, 11 layer turns or fewer plus up to four tip turns. Skewb — optimal in 11 moves or fewer. - Ivy Cube — optimal, 8 moves or fewer. Dino Cube — solved one edge at a time. - Tower 2×2×3 and Domino 2×3×3 cuboids — optimal within their own moves. - Megaminx and Kilominx — the twelve-sided puzzles, solved piece by piece with sequences that move only three pieces at a time. - Mirror Cube (entered by block depth) and Void Cube. Scanning that just works: - Guided capture of each face with a live overlay showing what the camera reads; it snaps automatically when the picture is steady. - Colours are worked out from all the faces together, so warm lamps and shadows don't fool it. - A check screen shows the whole puzzle as an unfolded net. Tap any sticker to recolour it, and if the pattern is impossible the app tells you exactly why: wrong sticker counts, a piece that can't exist, or a corner that was reassembled twisted. Follow along with confidence: - Every move is written out plainly ("Turn the right face up, away from you") beside a 3D model with a direction arrow, and the standard notation if you want it. - Play, pause, step back and forth, change the speed, and jump between stages on the big cubes. - Hands full? Turn on "Read each move aloud" and CommuniCube speaks every move, in the solution and in the Learn lessons; tap the move card for the next one. - Timer with scrambles for thirteen of the puzzles — random-state on the 3×3 and the Void Cube, random-move on the rest — plus inspection, ao5/ao12 and a chart of your times. - A Learn tab with animated notation for twelve of the puzzles and the full beginner method. - Colour themes and a colour-blind mode that puts a letter on every sticker. CommuniCube is 100% free for everyone, supported by ads. No subscriptions, no in-app purchases, no puzzles locked behind a paywall — every solver, the timer and every lesson are available to every user from day one. Want another puzzle or have an idea?

A twisty cube puzzle you turn with your finger. Two sizes: 2x2 and 3x3. TURN IT DIRECTLY Swipe a sticker in the direction you want that layer to go and the layer follows your finger - no notation to memorise. Drag outside the cube to turn the view instead. The view rotates freely in any direction, so you can look at the back and the bottom. Press and hold the cube to snap the view back to the start. THE SOLVING GUIDE IS IN THE APP Step-by-step instructions for whichever size you picked: seven layer-by-layer steps for the 3x3 and three steps for the 2x2, each with the algorithms you need. Every algorithm also shows a diagram of the starting shape and where each piece moves. STUCK? ASK FOR A HINT - OR LET THE APP SOLVE IT The hint reads which stage your cube is in and shows the moves to play next. Tap "Play it" and the app plays them for you. Tap Auto and the app keeps taking hints and solves the cube slowly, so you can follow along. Solves where you used a hint or Auto are not added to your records. RECORDS The app times your solve, counts your moves and keeps a personal best for each cube size on your device. The timer starts on your first turn and stops the moment the cube is solved. FREE WITH ADS A banner sits at the bottom of the game screen, and a full-screen ad appears once every three solves, when you move on to the next puzzle. Ads never cover the cube while you are solving or your result when you finish. No in-app purchases and no sign-up. Your records stay on your device. Available in Korean and English.
