Try the teaching style
In a trial session, stop at a move you cannot explain and use the available help. Ask whether the explanation gives you enough to finish the deduction yourself. Compare that experience with a lesson in our beginner course. The useful choice is the one whose explanation you can follow and apply.
Review the purchase in the app you use
Our app page explains optional Pro alongside browser alternatives. For Good Sudoku, review its current purchase screen and listing. A free download does not establish that every feature is included; prices and offers should be checked for your region.
