Wordoku Diário: Um Puzzle de Letras Gratuito Todos os Dias

Bem-vindo ao Wordoku Diário — um novo sudoku com letras que aparece todos os dias à meia-noite. Ao contrário do nosso modo ilimitado de Wordoku, a versão diária oferece-lhe um puzzle por dia idêntico para todos os jogadores do mundo. Substitua dígitos por letras, resolva a grelha e descubra uma palavra oculta de 9 letras na diagonal principal. É onde a lógica clássica do Sudoku encontra a emoção dos puzzles de palavras.

Wordoku has been a beloved crossword-magazine staple for decades, combining the deductive satisfaction of Sudoku with the thrill of word discovery. Our daily edition brings that tradition online: one puzzle per day, difficulty ramping up through the week, plus modern features like streak tracking, a complete archive, and instant sharing.

💡 Como Funciona

Todos os dias à meia-noite (hora local), aparece um novo Wordoku. As regras padrão de Sudoku aplicam-se — cada linha, coluna e caixa 3×3 deve conter cada uma das nove letras exatamente uma vez. O truque: as letras não são aleatórias — formam uma palavra oculta de 9 letras quando lê a diagonal principal do canto superior esquerdo para o inferior direito. A dificuldade segue um ciclo semanal: segunda/terça Fácil, quarta/quinta Médio, sexta/sábado Difícil, domingo Especialista.

🔤 O que Torna o Wordoku Especial?

Wordoku replaces the digits 1–9 with nine unique letters. Solving the grid is exactly like Sudoku — you use row, column and box constraints to place each letter. But there's a bonus layer: the main diagonal (top-left to bottom-right) spells a real word. That word is scrambled into the nine letters you see on the numpad, and discovering it is part of the fun.

Some solvers like to figure out the word first and lock in the diagonal, then complete the rest of the grid. Others solve purely by logic and let the word reveal itself at the end. Both approaches work — pick whatever feels most satisfying!

🧠 Did You Know?

A valid Wordoku word must have exactly 9 unique letters — no repeats. English examples include "ALGORITHM", "NIGHTMARE" and "BLUEPRINT". Our word lists are curated per language, so French, Spanish and German players will see real words from their own language.

📋 Regras do Wordoku Diário

  1. Standard Sudoku — Fill every row, column and 3×3 box with each of the nine letters exactly once.
  2. Letters not digits — The nine numpad buttons show letters instead of numbers. Keyboard letter-input is also supported.
  3. Hidden word — The main diagonal (top-left → bottom-right) spells a 9-letter word when the puzzle is complete.
  4. One solution — Every puzzle has exactly one valid solution.

⭐ Progressão de Dificuldade Semanal

  • Monday & Tuesday — Easy — 40 given letters. A relaxed start to the week.

  • Friday & Saturday — Hard — 26 givens. Deep deduction needed.
  • Sunday — Expert — Just 22 givens. The ultimate weekend brain-teaser.
🎯 Dica de Estratégia

Look at the sorted letter list shown above the grid. If you spot a word you recognise, try placing those letters along the diagonal first — this gives you nine free cells to anchor the rest of the puzzle.

🧠 Estratégias Chave do Wordoku

  • Guess the word early — If you can form a 9-letter word from the available letters, fill the diagonal first for a head start.
  • Use letter frequency — Some letters appear more often in row/column intersections. Just like number-scanning in regular Sudoku, scan for the most-placed letter first.
  • Box-line reduction — When a letter can only go in one row within a box, eliminate it from that row in other boxes.
  • Pencil marks matter more — With letters, it's harder to keep track mentally. Use notes generously.

💡 Dica de Profissional

If you're stuck, count how many times each letter already appears on the board. In a completed grid, every letter appears exactly nine times. A letter with seven placements has only two cells left — very constraining!
