4D Sudoku

Sudoku has always been about seeing relationships. 4D Sudoku extends that idea into four dimensions.

The board contains 81 cells. Instead of the traditional rows, columns, and boxes, each cell lies on six intersecting 3×3 planes. Every plane must contain the digits 1–9 exactly once.

Rotate the board in four dimensions. Long-press a cell to unfold its six related planes. Use pencil marks, undo and redo, and a guided tutorial designed to make the structure legible one step at a time.

FEATURES • Five difficulty levels with puzzles generated locally • A spatial board built for touch • Six-plane inspection for every cell • Guided lessons for the 4D rules and controls • Automatic local saving and resume • Solving timer, mistakes, history, and private statistics • Three visual styles with light and dark appearances • Completion animation and shareable results • Fully offline play • No account and no ads
