What's New in March 2026

We've been working on making OnSudoku better, and here's what's new:

New Game Engine

We've upgraded the game to a new engine under the hood. It plays the same, but the foundation is now faster and more reliable — especially on slower connections.

More Languages

OnSudoku is now available in Ukrainian, German, French, and Spanish. Switch to your preferred language using the menu at the top of the page.

Learn to Solve Sudoku

We've added step-by-step technique guides to help you improve your skills. Whether you're just starting out or looking to solve harder puzzles, check out the new articles:

• Last Free Cell
• Last Remaining Cell
• Last Possible Number

Each guide includes visual examples you can apply right away.

Results Page

After finishing a game, you now land on a dedicated results page with your performance stats and a motivational quote.

Difficulty Pages

We added separate pages for each difficulty level — Easy, Medium, Hard, Expert, and Extreme — making it easier to find puzzles that match your skill.

Player Profiles

Player profiles now show the date each player joined OnSudoku.

Performance Improvements

We cleaned up some old data in the background to make the game load faster and feel more responsive.

News Page

We replaced the forum with a dedicated news page where we share updates and improvements. This is the first post — bookmark it to stay in the loop.
