Free online sudoku sites supported by minimal ads have produced steady income since 2005:

https://www.samurai-sudoku.com

https://www.fiendishsudoku.com

https://www.extremesudoku.info

https://www.sudokuhints.com

https://www.sudokuprintables.org

I love this because it combines my favourite things! Nice work. Can you share what your income is from the sites combined roughly? Is this your side job or is it your main income now?

Is there a different backend/purpose behind each separate domain/site?

  • Yes samurai vs normal sudoku, different ranges of difficulty, different sets of puzzles, and a purpose built printables site.
