Sudoku - Solo/SharePlay

Nine digits. Eighty-one squares. One quiet mind. The classic Japanese logic puzzle, reimagined for Apple Vision Pro. Race a friend on SharePlay, or sit alone with a coffee and a 9×9 grid. Four difficulty levels, two play modes, and the slow satisfaction of a clean board. WHY THIS SUDOKU IS DIFFERENT Most Sudoku apps treat the puzzle as a solo race against the clock. Sudoku for visionOS does that, but it also does something almost no Sudoku app does: it lets you play with a friend. • COMPETITIVE MODE — Same puzzle, separate grids. First to solve it correctly wins, completion time tracked to the second. • COLLABORATIVE MODE — One shared 9×9, multiple hands. Talk it out, fix each other's wrong digits, finish together. Both modes run over Apple's SharePlay framework. One FaceTime call, one tap to play. No accounts, no friend codes, no waiting. FOUR DIFFICULTY LEVELS • EASY (46 clues) — A relaxed Sunday morning grid. • MEDIUM (36 clues) — The classic. What you'd find in a newspaper. • INTERMEDIATE (29 clues) — Eyes narrow. Look twice before each digit. • HARD (23 clues) — Near the theoretical minimum. Tea, not coffee. Every grid is freshly generated on your device using a backtracking solver. No two sessions get the same puzzle. BUILT FOR THE LONG MINUTES • Spatial 9×9 board, full size, easy to read at arm's length. • Tap a cell, pick a digit. No tutorials, no clutter. • Wrong digits quietly turn red. No popups, no punishment. • Completion time tracked silently. No leaderboards, no social pressure. • Solo mode works fully offline — no internet, no account, no analytics. • Three languages: English, French, Spanish.
