One can make a copy/paste of type directly in cells. Letters (Wordokuhref) and digits are accepted.

How does the step by step works?

Software solves the Sudoku just like an human and display each step of its progress to understand.
Sometimes, no logical reasoning is possible, the software make a random selectionhref among the possible values for a cell and continue, if an incoherence happens (the sudoku becomes unsolvable), it rolls back to the random step and try another value.
