Answers to Questions (FAQ)
What is a Wordoku? (Definition)
The wordoku is a logic game identical to sudoku but with letters (also called word sudoku, letter sudoku, alphabetic sudoku, alphadoku, mojidoku, mysmo ou mokitu).
The words formed do not have to have meaning (be in the dictionary), but generally at least one row or column or diagonal forms a valid word.
How to fill the Wordoku grid?
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).
How does the step by step works?
The solver of Wordoku fills the grid as a human would do and presents each of the steps of its progression to help, guide and understand (resolution by rows, columns and blocks).
Example: It is possible to copy-paste the workodu in the first cell W T P A T NY TI Y P Y S S TO N YS W IT A P to get the 9*9 grid:
| W | ␣ | T | ␣ | ␣ | ␣ | ␣ | ␣ | ␣ |
| ␣ | ␣ | ␣ | P | ␣ | ␣ | ␣ | ␣ | ␣ |
| A | ␣ | ␣ | T | ␣ | N | Y | ␣ | ␣ |
| ␣ | T | I | ␣ | Y | ␣ | ␣ | P | ␣ |
| Y | ␣ | ␣ | ␣ | ␣ | ␣ | ␣ | ␣ | S |
| ␣ | S | ␣ | ␣ | T | O | ␣ | N | ␣ |
| ␣ | ␣ | Y | S | ␣ | ␣ | ␣ | ␣ | W |
| ␣ | ␣ | ␣ | ␣ | ␣ | I | T | ␣ | ␣ |
| ␣ | ␣ | ␣ | ␣ | ␣ | ␣ | A | ␣ | P |
Sometimes the logical reasoning is indirect, the program analyzes which boxes are the most interesting to fill in and tries a letter among the possible values and tries to continue, if an inconsistency occurs (wordoku no longer has a solution) then it returns to the previous step and takes another value.
How to test if a wordoku has a unique solution?
dCode calculates all possible answers for the wordoku, not only the first one. To validate a homemade wordoku, it is the perfect choice to check whether there are multiple solutions but only one possibility.
