GDSudoku

This is a free Sudoku "game", implemented in Godot Engine. Several difficulty options are provided when generating the initial number distribution. Simply click the "Generate" button on the lower left then select the desired difficulty.

In order to ensure the created puzzle has a single solution, hard or very hard difficulties might take a few seconds to be fully generated.

This implementation was designed in order to be fully playable with keyboard and/or mouse. If you opt to use only the keyboard:

or Move cell selection up (it warps to the lower row)

or Move cell selection down (it warps to the upper row)

or Move cell selection left (it warps to the right column)

or Move cell selection right (it wars to the left column)

.. Toggle corresponding digit candidate in the selected cell.

.. + Set/unset corresponding value into the selected cell.
