Jia Cube

Let your hands find order. Jia Cube brings interactive 3D puzzles, illustrated lessons and personal timed challenges together. Take time to understand a move, follow an arrow or start a fresh scramble and challenge your previous result. Turn a sequence of letters into something you can see and try. SEVEN PUZZLES TO EXPLORE Discover 2x2, 3x3, 4x4 and 5x5 cubes, plus 2-, 3- and 4-layer pyramid puzzles. The 2-layer pyramid uses independently turning tips. Explore different structures and build familiarity with corners, edges, centers and layers. LEARN THROUGH PICTURES Compare a starting position with a target diagram, then work through the steps. Lessons introduce beginner layer-by-layer ideas for the 3x3 and concepts such as centers, edge pairing and reduction for larger cubes. Visual examples help you connect a move with its purpose instead of only memorizing notation. KNOW WHAT TO TURN NEXT On-puzzle arrows and next-move prompts show the intended movement. For cubes, U, D, L, R, F and B are explained as up, down, left, right, front and back, alongside turn direction. Guidance for the current scramble retraces its recorded moves in reverse. Illustrated lessons use example positions; this is not a camera scanner or an automatic layer-by-layer solver for any external puzzle. CHOOSE YOUR PACE Learn: combine diagrams, instructions and animated turns. Train: get ready, follow the 3-2-1 countdown and begin a personal timed attempt. A completed solve records time and moves; ending a started attempt early marks it unfinished. Free play: explore turns, change the view and scramble again without a running challenge timer. BUILT FOR TOUCH Swipe tiles to turn a layer, drag empty space to orbit the puzzle and pinch to zoom. Cubes also offer six face buttons and reverse-turn controls. Practice on iPhone or enjoy a roomier view on iPad. KEEP A HISTORY OF YOUR PRACTICE Review dates, times, move counts and scramble sequences. Filter results by puzzle and revisit completed and unfinished attempts. Use your history to set a clear goal for your next practice session. A SOUNDTRACK YOU CONTROL Optional ticking gives timed practice a steady rhythm. Ambient music starts switched off and can be enabled when you want it. Adjust both in your profile. CONTINUE IN YOUR LANGUAGE Choose Simplified Chinese, Traditional Chinese, English, Japanese, Korean, Polish, German, Portuguese or Spanish, or follow the system language. Sign in with Apple.
