Switched out of game to answer phone and check other apps, and ALL GAME PROGRESS WAS LOST! Puzzle went back to start. This has happened multiple times. Otherwise, it's one of the best 16x16 Sudoku puzzles I've played. Having many different levels of difficulty is great. EDIT: I'm finding a large number of puzzles that have 2 or more solutions, which is not good Sudoku design, and easily fixed by filling in just one more cell in the starting puzzle.

Dear Jimm, as we've communicated several times through emails, It's clear that the issue of lost progress is because of some device-optimizer-app in your device that is blocking our app from saving your progress in the file (a file that we create/modify on your device's storage). There is no bug in the app. I hope it helps you! Thanks you so much!

I love this game, it has good tools, few ads, very adjustable difficulty levels. Only a few bugs like a score being listed mid puzzle that won't go away and blocks playing, or other minor things. All fixed by simply restart to reset without losing progress. My favorite for it's 16x16 sudoku, which is hard to find. Highly recommend this one!!

The notes don't stay on the board when you click off of the pencil icon to put a permanent number/letter on the board, only mildly annoying. The truly annoying part is when you put a piece in its correct spot the +whatever number is stuck in the middle of the board and you can't see that part of the board. The only way I've found to get rid of it is go to a different app, click on something then go back to the game. Which is pointless because it does it again when you put another piece on.

Dear user, we have a feature called "Always-On Pencil Notes". It is turned OFF by default. To turn it ON, you can go to Settings > Sudoku board controls. When you turn it ON, the pencil notes will be visible even if the pencil is turned OFF from the board side. Hope it helps you! For more help, you can write us at contact@gujmcq.in.
