Sudoku Pro is a full Sudoku to play and a trainer that teaches you Sudoku: from your very first number to Pro and Expert techniques like Swordfish and XY-Chain. A learning path takes you through 20 techniques, each with its own practice puzzles, and every hint teaches instead of giving the answer away. If you only want to play, you never have to switch it on. Everything you expect from a Sudoku is here: 4x4, 6x6 and 9x9 across four tiers, Killer, Samurai on iPad, a daily puzzle, notes, streaks and statistics. Every puzzle is generated fresh, has exactly one solution and can be solved without guessing. Learn Sudoku, step by step: * Learning path: 20 techniques across four tiers, from Naked Single to XY-Chain. How to Play shows an example for each one and where you stand: new, seen, practicing, mastered. * Practice puzzles for every technique: without it, only harder techniques get you through. Solve three without any help or mistakes and the technique counts as mastered. * Pro and Expert techniques, including Skyscraper, 2-String Kite, W-Wing, XYZ-Wing, Unique Rectangle, Simple Coloring and Finned X-Wing. * Hints in two steps: first a nudge like "Look at row 3", then, if you want, the technique by name with its pattern drawn on the board. * Trainer: explains the technique on your own grid, move by move, instead of a textbook example. * Puzzle profile after a win: which techniques the puzzle used, where you needed hints, and which technique to practice next. * Check notes: shows you where a candidate is missing or a note is already ruled out. * Prefer to find your own mistakes? Errors don’t have to be marked right away. * 4x4 and 6x6 for kids and beginners: I built them so I could play with my kids and teach them the logic. Play your way: * Classic in 4x4, 6x6 and 9x9, across four difficulty tiers. Pro and Expert are now tougher. * Killer: cages with sums that tell you right away whether a sum still works out. * Samurai (iPad only): five overlapping 9x9 grids solved as one 21x21 frame. * Daily puzzle: the same puzzle worldwide on any given day, with a streak and a calendar. * Notes, blocked notes, auto notes, focus mode and helper mode. * Twelve handcrafted themes, including the hand-drawn Felt Pen, from rainbow colors to high contrast. * Statistics, best streak and 15 achievements, all on your device with no sign-in. * Share your logic: export a timelapse video of your solve. * A daily reminder at a time you choose, but only if you want one. * 45 languages. On iPad: the newspaper edition. The iPad gets a world of its own: a front page, an almanac, its own typography. Not a stretched iPhone. Or something else entirely: the hand-drawn Felt Pen theme. In pen mode the keypad folds away and the board takes the space. Prefer the familiar look? Switch to the classic layout. Why this app exists: I am a solo dev and I’ve been a Sudoku lover for years, but lately, finding a good app has felt like a puzzle of its own. And not the fun kind. Subscriptions, tracking, flashing banners and "collect 100 gems" pop-ups. I just want my coffee and a Sudoku. So I built it myself. * Pay once, keep forever: no subscriptions, no hidden IAPs, no ads, no account. Just a fair price for a tool that does its job. * Everything on your device: the app needs no internet. Your puzzles, your streak and your statistics stay where they belong. I don’t track you. I only care about your feedback! Accessibility is built in, not retrofitted: VoiceOver throughout, Dynamic Type on the board, a high-contrast theme, haptics you can switch off, and a dot notation for anyone who reads patterns faster than digits. Own the grid and rediscover the pure joy of logic. Happy puzzling, Tobias

Verdict
The clearest difference is price: Demon Nights at Free against Sudoku Pro's $4.19. Demon Nights also leads on rating (5.0 vs 4.8) and iOS requirement (16.4 vs 18.0). Sudoku Pro's advantage is ratings volume (5 vs 1). On review sentiment, update cadence, ads and in-app purchases there is nothing between them.

Demon Nights is free to download; Sudoku Pro costs $4.19 up front. Neither carries in-app purchases, so what you see is what you pay.
Demon Nights holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Sudoku Pro has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
Both ship on a similar rhythm, roughly every 5 days. The most recent releases landed on October 19, 2026 and October 24, 2026 respectively.
