Wordoku
Sudoku played with nine letters instead of digits, often hiding a word in a row or diagonal.
Controls
Click a cell, then pick a letter from the on-screen set to place it.
How to Play
Wordoku follows exactly the same logic as classic sudoku, but swaps the numbers 1 to 9 for nine different letters. Fill the 9x9 grid so that every row, every column and every 3x3 box contains each of the nine letters once and only once. Because letters replace digits, you solve by position and elimination just as you would with numbers.
Many Wordoku puzzles hide a bonus: read a particular row or diagonal once the grid is complete and a real word appears. If the underlying method feels unfamiliar, our step-by-step guide explains the same row, column and box logic you will apply here.
Tips & Tricks
- Treat the letters as abstract symbols; you do not need to guess the hidden word to solve the grid.
- Pencil in candidate letters for tricky cells, just as you would candidate numbers.
- Once the grid is done, scan rows and diagonals to spot the concealed word.
Frequently Asked Questions
How is Wordoku different from ordinary sudoku?
The rules are identical, but the grid is filled with nine letters instead of the digits 1 to 9. The logic of no repeats in any row, column or box is unchanged.
Is there really a hidden word?
Often, yes. Many puzzles are built so that a completed row or diagonal spells out a word, but finding it is a bonus, not a requirement for solving.
