Jigsaw Sudoku Diário: Um Puzzle Gratuito de Regiões Irregulares Todos os Dias

Bem-vindo ao Jigsaw Sudoku Diário — um novo puzzle de regiões irregulares que aparece todos os dias à meia-noite. Ao contrário do nosso modo ilimitado de Jigsaw Sudoku, a versão diária oferece-lhe um puzzle por dia idêntico para todos os jogadores do mundo. É a mesma lógica de Sudoku viciante que adora, mas com formas de região imprevisíveis que o forçam a repensar cada jogada — num desafio diário partilhado onde pode comparar tempos, construir séries e partilhar resultados sem spoilers.

O Jigsaw Sudoku — também conhecido como Sudoku Irregular, Nonomino Sudoku ou Sudoku Geométrico — substitui as caixas 3×3 padrão por nove regiões de forma única. A nossa versão diária segue a tradição dos puzzles de jornal: um puzzle por dia, progressivamente mais difícil ao longo da semana, com funcionalidades modernas como o acompanhamento de séries, um arquivo completo de puzzles e partilha instantânea.

🧩 O que Torna o Jigsaw Sudoku Diário Especial?

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.

📋 Regras do Jigsaw Sudoku Diário

If you are new to Jigsaw Sudoku, here are the rules — they are almost identical to classic Sudoku:

1. Row rule — Each row must contain the digits 1–9 exactly once.
2. Column rule — Each column must contain the digits 1–9 exactly once.
3. 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.

⭐ Progressão de Dificuldade Semanal

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.

🧠 Estratégias Chave para o 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.
