How Sudoku Journey works
- 1 Start at Level 1 with a beginner-friendly Sudoku puzzle that has plenty of starting clues.
- 2 Solve each puzzle using logic - fill every row, column, and 3×3 box with the digits 1–9.
- 3 Complete a level to unlock the next one. Each new level has fewer clues and requires more advanced techniques.
- 4 Track your progress across all 100 levels. Your progress is saved automatically - pick up where you left off anytime.
Why play Sudoku Journey?
Sudoku Journey is the best way to improve at Sudoku step by step. Instead of jumping between random puzzles, you follow a structured path from easy to hard that builds your skills gradually. Levels 1–33 teach scanning and elimination, levels 34–67 introduce naked pairs and locked candidates, and levels 68–100 challenge you with advanced techniques like X-Wings and swordfish. It is a complete Sudoku training program that doubles as a satisfying brain workout.
Tips for completing Sudoku Journey
- Don't rush - accuracy matters more than speed. A mistake early on can make the entire puzzle unsolvable.
- Use pencil marks on medium and hard levels to track possible candidates for each cell.
- When stuck, look for hidden singles: a digit that can only go in one cell within a row, column, or box.
- On harder levels, learn to spot naked pairs and pointing pairs - they eliminate candidates and unlock new placements.
- Take breaks between difficult levels. Returning with fresh eyes often reveals patterns you missed before.
Sudoku Journey - frequently asked questions
What is Sudoku Journey?
Sudoku Journey is a free progressive Sudoku challenge with 100 handcrafted levels. You start at Level 1 with an easy puzzle and unlock each subsequent level by completing the one before it. The difficulty increases gradually from beginner-friendly boards (75+ clues) to expert-level puzzles (28 clues) that require advanced solving techniques.
Is Sudoku Journey free to play?
Yes, Sudoku Journey is completely free. All 100 levels are available with no sign-up, no downloads, and no ads on the game board. Play on any device - desktop, tablet, or mobile.
How many levels are in Sudoku Journey?
There are exactly 100 levels. Levels 1–33 are easy (75–76 starting clues), levels 34–67 are medium (30–42 clues), and levels 68–100 are hard (28–42 clues). Each level has a unique, pre-generated puzzle with exactly one solution.
Can I replay a completed Sudoku Journey level?
Yes, you can revisit and replay any level you have already completed. Your completion status stays saved, so replaying a level won't affect your progress.
Does my Sudoku Journey progress save automatically?
Yes. Your completed levels and any in-progress puzzle are saved in your browser automatically. You can close the tab and come back later - your progress will still be there.
What Sudoku techniques do I need for the harder levels?
Early levels only require basic scanning and elimination. Medium levels introduce naked pairs, hidden pairs, and locked candidates. The hardest levels (68–100) may require X-Wings, swordfish, and other advanced chain-based techniques. Sudoku Journey teaches these skills naturally as the difficulty increases.
How is Sudoku Journey different from regular Sudoku?
Regular Sudoku gives you a random puzzle at a fixed difficulty. Sudoku Journey is a structured progression - each level builds on the skills from previous ones, making it ideal for players who want to systematically improve from beginner to expert level.
How long does it take to complete all 100 levels?
It depends on your skill level. Beginners might spend 5–15 minutes per easy level and 20–45 minutes on hard levels. Experienced solvers can finish easier levels in under 5 minutes. Most players complete all 100 levels over several weeks of casual play.
