Exceptionally good for the older brain

My husband has been playing this version of Sudoku for the past month. I have noticed quite an improvement in his memory issues. We both enjoy trying to identify (guess) the painting underneath before it’s revealed.

Response from developer

Thank you. We love that you’re guessing the painting together.

I have been playing for years but when you reworked to the weird art stuff, i no longer have access to any of the sudoku libraries. i was trying to complete the evil book

Annoying UI

Very easy to accidentally erase all progress

Response from developer

Please update to the latest version.

can no longer play without a subscription

this app was great until it locked me out of all the sudokus and said I need a subscription to play. Seriously no free content? So disappointing.

Intrusive Ads

Ads taking over entire screen and not letting complete the game
