A new chapter for our puzzle community: Classic Sudoku arrives

For years, our community has enjoyed the strategic depth and relaxing essence of our solitaire collection. Today, we’re thrilled to announce a major expansion of our puzzle universe: Classic Sudoku is officially here!

We’ve poured the same commitment to quality, intuitive design, and modern features that you love about our solitaire games into this timeless number puzzle. Whether you’re a beginner or a grid master, your next challenge awaits.

The complete Classic Sudoku experience

Our version of Classic Sudoku is designed to cater to every skill level and ensure the smoothest solving experience possible. We believe that a great puzzle app should feel like a trusty paper puzzle, but with better tools and exceptional look and feel.

Five levels of difficulty

We know that a good Sudoku challenge depends entirely on the difficulty. You can test your skills across five finely tuned levels: easy, medium, hard, expert, and evil. The “evil” puzzles are specifically crafted to demand advanced techniques like X-Wing and Swordfish — they’re truly designed to push your limits 😉 .

Modern solving tools

We’ve included all the features you need to tackle those tougher grids:

• Undo: Never worry about a wrong step again. Our full history tracking allows you to confidently backtrack through your game.
• Candidate tracking: Effortlessly mark and manage potential numbers in each cell, just like using a pencil — but much cleaner.
• Extensive hinting: Our multi-tiered hint system doesn’t just give you the answer; it offers detailed, contextual breakdown on the logic required to find the next step, teaching you how to solve the puzzle.

More puzzles, more challenges: what’s next

This is just the start of our journey into logic puzzles. We’re committed to making our platform the best destination for a diverse array of single-player games.

Later this year, look forward to even more brain-bending content, including:

• Sudoku variations: We will be rolling out popular variations like the deep, mathematical challenge of Killer Sudoku and the massive, intersecting grids of Samurai Sudoku.
• Solitaire renaissance: We’re continuing to expand our roots by adding more favorite variations to our solitaire collection, ensuring there’s always a new way to deal the cards. Our goal is to have the biggest free online solitaire collection.
