WORDOKU
Learn how to play Wordoku.
Wordoku is a word-based twist on classic Sudoku. Instead of numbers, each puzzle uses a unique 9-letter word with no repeating letters. Your goal is to fill the 9×9 grid using all nine letters so that the puzzle follows the traditional Sudoku rules.
Each row, column, and 3×3 box must contain all nine letters exactly once. The puzzle is solved when you fill in all the cells correctly.
Example 3×3 box:
Each 3×3 box must contain all 9 unique letters. Clues (darker) are given; you fill the rest.
Use the keypad to input letters. You can also use the "Erase" and "Undo" buttons to remove a letter or undo your last move if you make a mistake.
Erase
Clears the selected cell (removes both the letter value and any pencil marks). Only works on cells you've filled, not the given clues.
Undo
Reverts your last move. Works for both letter entries and pencil marks. Can undo multiple moves in sequence.
Pencil Mode
Toggle pencil mode to make small notes. When active, clicking letters adds them as pencil marks (small letters in a 3×3 grid) instead of setting the main value. Click the button again to exit pencil mode.
Pencil marks example:
Pencil marks appear as small letters in a 3×3 grid, arranged alphabetically based on the puzzle word. They help you track possible letters for a cell without committing to a value.
To add pencil marks, click the Pencil button to toggle pencil mode, then click letters on the keypad. Pencil marks are automatically cleared when you enter a solid letter value in that cell.
Wordoku is a great way to challenge your brain and improve your vocabulary.
