The grid is yours now. Some of you like the lines thin, some thick; some want them dark, some light. So we made it adjustable: open Settings › Game Settings › Grid Lines and set Grid Contrast (Light, Standard, Strong) and Box Lines (Thin, Standard, Thick) on a live board. The game, the lessons and the tutorial all follow your choice, and new players pick theirs while setting up. Thank you for telling us what you wanted. Keep it coming. 5.0.1 Note mode shows full-size numbers again. In 5.0.0 the keys turned into nine tiny pencil marks while notes were on, and they were hard to read. The keys now fill with colour the way they used to, and the number stays the size it is everywhere else. The number pad has a clearer edge again too. The outline around each key had gone too faint in 5.0.0, which showed most in light mode and on a tablet. Thank you to the players who wrote in about both. 5.0.0 Daily Challenge. A new puzzle every day at each of the six difficulty levels, the same ones every other player gets. Every day you finish is marked on your calendar, and playing daily builds a streak. A Streak Shield covers you if you miss a day. Interactive Tutorial. Learn Sudoku by playing it. A real board walks you through your first game step by step: filling a row, scanning for a hidden number, taking notes, using a hint, and fixing a mistake. Open it from How to Play, or when you pick Easy for the first time. Coach's Report. When a game ends, it shows what went wrong. You get your own board back at the moments you made a mistake, the technique that settles that cell, and the lessons to review. Replay. Watch any finished game back, move by move, with your notes as you made them. Open it from the results screen or the Coach's Report. Zen mode. No timer, no mistake limit, and nothing is recorded. Just the puzzle. 36 solving techniques instead of 26. Ten new ones, each with a lesson, a Try It board and its own diagram in the Technique Library. Skill Map shows how often each technique has come up in your games. Six number pad layouts instead of two, including a 3x3 keypad with the biggest keys, and two 3x3 pads side by side so notes and numbers each get their own. Undo now has a Redo next to it. Your language, your pick. Choose any of 47 languages in Settings, independent of your phone's language. Thank you for every piece of feedback. Please keep it coming.

The Big Screen Update is here. Sudoku now runs beautifully on iPad and Apple Silicon Macs, with layouts rebuilt from the ground up for larger screens. This is not a stretched phone app. On iPad you get proper layouts in both orientations, full Split View, Slide Over and Stage Manager support, and your puzzle, notes and timer stay intact when you resize the window mid game. On Mac the app runs natively with full hardware keyboard support for number entry, arrow keys, notes, undo and pause. We also reworked the Smart Hint engine so it teaches instead of just solving. A hint explains which of 26 human techniques applies and why, highlighting the cells step by step before it places a number. The Technique Library walks you through every technique with a worked example you can try yourself, and a new Sudoku Terms glossary explains every word a hint or lesson uses in plain language, with a quick example. Also new in this release: Auto-Complete. When only a few cells are left and the rest is forced, let the app fill them in for you. You choose whether it asks first or completes the grid instantly. Create your own theme. Choose the colors for the board, your numbers, the grid lines and the accent, and the whole app follows along. A cleaner, calmer, more modern look on every screen. Accessibility improvements, including an adjustable board font size and a quieter, focus friendly interface. More languages, so more players can learn Sudoku in their own. Thank you for every piece of feedback. Please keep it coming. 4.0.1, from your feedback: When "Show mistakes instantly" is turned off and your board is full but the puzzle isn't solved yet, the game now tells you and can point out the cells that still need fixing. A new setting, "Block conflicting notes": turn it off to pencil in any candidate freely, even one already placed in the same row, column or box. The color highlight for notes matching your selected number wasn't appearing in some themes. That's now fixed, so it stands out clearly in every theme. 4.0.3, from your feedback: Send feedback and get our reply right inside the game. When we answer, it appears the next time you open the app, and you can write back. Haptics got a full upgrade: mistakes now feel clearly different from completions, finishing a row, column or box sweeps across the board cell by cell, and winning buzzes in time with the confetti. The number pad registers every tap more reliably, especially 1 and 9 at the edges. You can now dismiss the keyboard while writing feedback.
