Sudoku Cubes

You've solved a thousand sudokus. Never one like this.

Once you know the tricks, flat sudoku runs on autopilot. Sudoku Cubes wraps six puzzles around one cube that floats in your own room and links them at the edges, so every face you crack hands you clues for the next. Turn the cube, follow the chain, and feel that first-time aha again.

THE ANSWER'S AROUND THE CORNER Each face is a classic 9×9 sudoku. Where faces meet, cells that touch across an edge must differ, and the three cells at a corner must all be different. A face that looks stuck often isn't: its clue is waiting next door.

A LEVEL FOR EVERY MOOD • Easy: a cup-of-tea solve while you learn the edges. • Medium: a satisfying daily workout. • Hard: for when regular sudoku stopped being hard. • Ultra Hard: long chains of logic around the whole cube. Every puzzle has one solution, reachable by logic alone. No guessing.

MADE FOR YOUR ROOM • The puzzle sits in your space while your room stays around you. • Pinch and drag to roll the cube with bare hands or Touch controllers; let go and it settles on the nearest face. • Play seated or standing, offline, at your own pace. • Hints teach the next step, notes tidy themselves, and undo goes as far back as you like. • Soft pencil ticks, kalimba chimes, and a fanfare when the cube comes together.
