Wordoku
Wordoku combines the classic logic-based puzzle mechanics of Sudoku with letters instead of numbers. Instead of filling a grid with the digits 1 through 9, your goal is to place a specific set of nine letters into a 9×9 grid so that every row, column, and 3×3 block contains each letter exactly once.
The gameplay requires careful deduction and forward planning, as guessing will often lead to mistakes later on. Since the letters usually form a 9-letter word, spotting the hidden word can sometimes give you a hint, adding an extra layer of wordplay to the traditional number puzzle format.
Controls
Wordoku is fully playable with a mouse or touch screen. Simply click or tap on an empty cell to select it, and then choose the letter you want to place from the on-screen options or use your keyboard to type the letter directly.
Tips that actually help
Always start by looking for rows, columns, or 3×3 blocks that are already mostly filled, as these will have the fewest missing letters and are easiest to solve. Using the process of elimination is key; if you know a specific letter must go in a certain block, you can often rule out cells in intersecting rows and columns.
