Wordoku Game

Wordoku swaps the digits of a classic Sudoku grid for nine letters. The rules are otherwise identical: every puzzle is freshly generated, so no two sessions use the same solution, and solving one comes down to the same row-column-block logic Sudoku players already know, just read as letters instead of numbers.

Pick a difficulty before you start — Beginner, Intermediate or Advanced — which sets how many cells are already filled in for you. From there it is pure deduction: work out which letter belongs in each empty square so that every row, column and 3x3 block contains each of the nine letters exactly once.

Controls

Wordoku plays with mouse, touch or keyboard, and offers two input styles you can switch between: Cell First, where you click an empty square and then pick a letter, and Letter First, where you choose a letter and then tap every square you want it placed in. A memo mode lets you pencil in candidate letters before committing to an answer.

Tips

• Turn on "fill the board with notes" early — it pencils every letter that is still legal into each empty cell, which makes scanning for eliminations much faster than working from a blank grid.
• If you already know where a letter has to go but not which one belongs, switch to Letter First mode instead of hunting cell by cell.
• Hints and the auto-solver are there if you get stuck, but both cost points off your final score, so save them for genuine dead ends rather than routine cells.
• On Advanced puzzles, turn on "play without time" if you'd rather reason through the logic carefully than race the clock.

Wordoku suits anyone who already likes Sudoku and wants the same deductive puzzle with a different visual read — quick rounds on Beginner, longer sits on Advanced.
