We are excited to share the latest version of Sudokion, and it is our most polished and enjoyable release yet. This update is all about making your experience smoother, faster, and more rewarding, while keeping the heart of Sudokion exactly as you love it. A more refined experience We have gone through the app with care and attention to detail, simplifying some screens and making them easier to navigate. Menus feel more intuitive, settings are clearer, and everything is designed to get you into your next puzzle with less effort and more enjoyment. Performance and stability improvements Behind the scenes, we have worked hard to make Sudokion run better than ever. We resolved several issues that could occasionally disrupt play, so puzzles now load more smoothly and the entire experience feels more reliable. The result is a calmer, more consistent journey from puzzle to puzzle. A focus on player feedback Many of these changes came directly from you, our players. Your feedback has helped us understand what matters most: speed, simplicity, and a frustration-free puzzle experience. We are grateful for the support of our community and are always listening for ways to make Sudokion even better. Why this matters Sudokion is about more than solving puzzles. It is about enjoying the process, feeling energised, and celebrating the sense of accomplishment that comes with each completed grid. These updates make that journey smoother and more enjoyable, so every player—whether a beginner or an expert—can focus fully on the fun of solving. A big step forward This release is a significant improvement. The app feels sharper, cleaner, and more inviting. It is not just a set of fixes—it is a step forward in making Sudokion the best Sudoku experience available. And of course, everything you already love about Sudokion is still here: Beautifully designed puzzles for every level, from quick 5x5 grids to epic 8x8 challenges. Daily puzzles and rolling leaderboards to connect you with our global community. Helpful features like diagonal lines and challenge modes, designed to support or stretch you. A safe, ad-free environment where the focus is entirely on the joy of puzzling. We are proud of this update, and we think you will feel the difference the moment you play. Thank you for being part of the Sudokion community, and for helping us continue to shape the evolution of Sudoku. Download the update today and enjoy the most refined version of Sudokion yet.

We have deployed the ultimate challenge. To really test your solving skill. No timer, no notes, no clues.

We are letting users who have not yet registered try all puzzle sizes and levels. However, we are limiting the user to 5 puzzles per 24 hours. Why? Because when users are signed in they are able to use the full power of Sudokion and this really helps us understand how our app is being used. There are important fixes and updates too. We are constantly trying to improve the app and update Sudokion regularly.
