It helps increase your memory power and thus the brain power. In this particular version you should add the feature where by a incorrect number will not be accepted into a square not meant for it. Player immediately will try another number. Of course the error count can go up by one, that is fair! Hard to take note of the green and red background when the correct and incorrect fit occurs! Thank you. It is a fantastic game on the whole. A true blessing. ### 3/5 — Paid for ad-free… still get ads. *2024-03-10* Title sums it up. Hopefully apple refunds me, but it would honestly just be nice not to get an ad every 90 seconds. **Developer response:** Hi! Thank you for reporting this issue and for having purchased the ad remover. Please update the app to version 5.5.9. and the ads should be gone. If they are not, please click on "restore purchase". Thank you very much. For further support, please contact us at info@appgeneration.com. Best regards ### 4/5 — Good Game with one problem *2023-11-28* I like this Sudoku better than a previous one I had because of its many options.
