As I told you, this is the only place on the web that you can find these puzzles. If you like Spark Sudoku why not buying my book Spark Sudoku Challenge ? You will be happier and everyone will envy you.
You could also try a more complex version the Super Spark Sudoku in my book Super Spark Sudoku Challenge. This variant is a little bit larger so you need to use numbers from 1 to 12. I am going to publish new Super Spark puzzles soon (right now you could try the old ones - look in menu).
Enjoy !
