Daily Jigsaw Sudoku: A Free Irregular-Region Puzzle Every Day
Welcome to Daily Jigsaw Sudoku — a new irregular-region puzzle that appears every day at midnight. Unlike our unlimited Jigsaw Sudoku mode, the daily version gives you one puzzle per day that is identical for every player worldwide. It is the same addictive Sudoku logic you love, but with unpredictable region shapes that force you to rethink every move — wrapped in a shared daily challenge where you can compare times, build streaks, and share results without spoilers.
Jigsaw Sudoku — also known as Irregular Sudoku, Nonomino Sudoku, or Geometric Sudoku — replaces the standard 3×3 boxes with nine uniquely shaped regions. Our daily version follows the newspaper puzzle tradition: one puzzle per day, progressively harder through the week, with modern features like streak tracking, a complete puzzle archive, and instant sharing.
Every day at midnight (local time), a new jigsaw sudoku puzzle appears. The grid uses nine irregular regions instead of the standard 3×3 boxes — each region still contains exactly 9 cells. Difficulty follows a weekly cycle: Monday/Tuesday Easy with more givens, Wednesday/Thursday Medium, Friday/Saturday Hard with fewer clues, and Sunday Expert with the most complex region shapes.
🧩 What Makes Daily Jigsaw Sudoku Special?
Daily Jigsaw Sudoku combines two powerful hooks: the social element of a shared daily puzzle (like Wordle) and the deeply satisfying spatial reasoning of Jigsaw Sudoku. Every player gets the same region layout, the same givens, and the same solution — so when you share your results, the comparison is meaningful.
What makes Jigsaw Sudoku uniquely challenging is that the irregular regions break your spatial intuition. In classic Sudoku, you develop an instinct for the 3×3 grid — you know which box a cell belongs to at a glance. Jigsaw Sudoku strips that away. You must constantly scan the coloured regions to understand which cells share a constraint, making every placement a fresh logical challenge.
Jigsaw Sudoku puzzles were popularized in the early 2000s by Japanese puzzle publishers. The variant is also called "Nonomino Sudoku" because each region is a nonomino — a polyomino made of exactly nine cells. There are over 1,000 distinct nonomino shapes, giving puzzle designers nearly infinite variety.
📋 Daily Jigsaw Sudoku Rules
If you are new to Jigsaw Sudoku, here are the rules — they are almost identical to classic Sudoku:
- Row rule — Each row must contain the digits 1–9 exactly once.
- Column rule — Each column must contain the digits 1–9 exactly once.
- Region rule — Each coloured irregular region must contain the digits 1–9 exactly once.
The only difference from classic Sudoku is rule 3: the regions are irregular shapes instead of 3×3 squares. This single change transforms the puzzle's logic significantly.
⭐ Weekly Difficulty Progression
Like our classic daily Sudoku, the jigsaw variant follows a weekly difficulty curve:
- Monday & Tuesday — Easy — More generous givens and simpler region shapes. Perfect for learning Jigsaw Sudoku.
- Wednesday & Thursday — Medium — Fewer givens, requiring cross-region scanning and naked/hidden singles.
- Friday & Saturday — Hard — Complex interlocking regions with advanced techniques like pointing pairs and box–line reduction adapted for irregular shapes.
- Sunday — Expert — The most deformed regions with minimal clues. Demands full mastery of jigsaw-specific elimination.
In Jigsaw Sudoku, region boundaries are your best friend. When an irregular region overlaps two rows partially, you can often deduce which digits must go in the overlapping cells. Look for regions that span a single row or column heavily — they create powerful elimination opportunities that don't exist in classic Sudoku.
🧠 Key Strategies for Jigsaw Sudoku
- Region scanning — Colour-code regions mentally and scan each one for missing digits, just like scanning boxes in classic Sudoku.
- Cross-hatching with irregular shapes — Extend row and column logic across irregular boundaries to eliminate candidates.
- Overlap analysis — When a region overlaps a row or column partially, the non-overlapping cells in that row/column cannot contain digits already in the region.
- Pointing pairs in jigsaw regions — If a digit in a region can only go in cells that share a row or column, eliminate that digit from the rest of that row/column.
- Region–row/column interaction — Jigsaw-specific technique: identify sets of cells where a region and a line share exactly N cells with N candidate digits.
Classic: 9 identical 3×3 boxes — predictable, symmetric.
Jigsaw: 9 irregular regions — unique shapes, no symmetry assumed.
Effect: Jigsaw makes "box–line reduction" unpredictable because regions can span 2–3 rows, creating more complex interactions. Solvers often find Jigsaw puzzles 20–30% harder than equivalent classic puzzles.
