Magic Sudoku

Magic Sudoku is a calm, carefully graded collection of classic and variant sudoku, from gentle warm-ups to puzzles that will make you think hard. Four collections of 30 puzzles, each running from Beginner to Master: Classics, Side Quests, Plot Twists and Deep Water. Twenty-four variant rules, each with its own twist: Killer, Little Killer, Sandwich, Thermo, Arrow, Kropki, Full Kropki, XV, Full XV, German Whispers, Wide Whispers, Renban, Palindrome, Between Lines, Parity Lines, Modular Lines, Odd / Even, Quadruples, Clone, Shadow, Windoku, Disjoint Groups, Anti-knight and Anti-king. Every puzzle explains its rules before you start, so a new variant never feels like guesswork. Play your way: • Notes and colours • Select several cells at once and fill them together • Undo and redo • Hints when you're stuck, from the setter's tips or a solver that reads your board • Killer cages show the combinations that still fit • Purist mode, for pen-and-paper solving with no checks • Light and dark themes Set your own puzzles for other players, and play the ones the community makes. Join the optional leaderboards under a nickname to compare your times. The collections play fully offline. Puzzles, hints and your progress live on your phone, so you can solve on a plane or underground. Sign in if you like, to set puzzles, join leaderboards and share your scores; it's never required to play. No ads.
