Wordoku Solver

Wordoku(also known as Mojidoku, Word Sudoku, Letter Sudoku, Alphadoku, Godoku, Mysmo or Mokitu) is a variant of Sudoku in which the numbers are replaced by nine distinct letters.

The mathematical structure remains exactly the same: a 9×9 grid divided into nine 3×3 squares, where each symbol must appear only once per row, column and square.

It is not necessary for the words formed to be meaningful (i.e., dictionary-like), but generally, at least one row, column, or diagonal forms a valid word.

As for a sudoku, enter the grid, letter by letter in the cells. With an online version on computer or smartphone, the best way is to copy and paste (in the first cell).

The Wordoku solver applies the same logical principles as a classic Sudoku solver (in a human-like fashion).

The solution process unfolds in two main phases:

— Deterministic logical solution: the program analyzes the rows, columns, and blocks to identify letters with a single possible position, cells with only one candidate, and exclusions resulting from cross-constraints.

— Backtracking: if no direct deduction is possible, the algorithm selects a cell with few candidates, tests a possible letter, and then continues solving. If a contradiction arises (no solution compatible with the constraints), it returns tothe previous step and tries another possibility.

This method guarantees that any solution found strictly adheres to the Wordoku constraints. The detailed steps allow the user to understand the reasoning behind the solution.

dCode is an exhaustive solver; it calculates all possible answers for the wordoku puzzle, not only the first one.

To validate a homemade wordoku puzzle, it's the perfect choice to verify that there isn't multiple solutions and that there is only one possibility.

As with Sudoku, it's possible to define grids of any size, even with irregular blocks. dCode has a solver for this: Irregular NxN Sudoku Solver !
