Sudoku Ignite is sudoku with room to grow. Start with a relaxed 9×9, then push into puzzles you won't find in most apps: irregular Jigsaw grids, 16×16, and enormous 25×25 Mega boards. Five difficulty tiers — Easy to Guru — mean there's always a next step. Every puzzle is graded by the logic it takes to solve, so difficulty actually means something. Stuck? The built-in guide finds a certain next move and shows you why it works — so you finish with the technique, not just the answer. Come back every day for the Daily Challenge — one fresh Classic or Jigsaw puzzle — and build a streak. Your statistics track best and average times per grid and difficulty, mistake-free "perfect" solves, and a calendar of your daily wins.

The library has been rebuilt from scratch, 2000 unique boards across the app, so nothing repeats as you work through a grid. Hints that explain themselves Every hint now names the strategy behind it and shows why the move works, rather than just pointing at a square. A new Techniques guide covers each one with a worked example, from naked and hidden singles up to X-Wings and colouring, so the terminology becomes familiar as you play. Hints that notice your mistakes If a wrong entry is blocking progress, the hint points it out and offers to clear it, instead of guiding you toward a move that breaks the rules. Daily Challenge Difficulty is far steadier day to day. Statistics now include your best and average times, clean runs and the difficulty range you've played, plus a day-by-day history of every daily you've finished. Also in this release • Consistent difficulty within each level set, so Medium feels like Medium • Hints reach further on Expert and Guru boards, and always have something useful to offer • A number of layout fixes on smaller screens and at larger text sizes Your existing progress is maintained. All levels you have already started or finished keep the puzzles you were playing. ### 1.0 — 2026-08-06 No release notes. ## More apps by Groth Galleries, LLC - [Nightlog: Milky Way Planner](https://appshunter.io/ios/app/nightlog-milky-way-planner/id6780690283) All apps by Groth Galleries, LLC: https://appshunter.io/developer/6780690285 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
