Fun. You can put in scribblings. When you place a number down that you're sure about, it automatically removes that number from your related scribblings The size of all the numbers are comfortably large. You can highlight specific numbers by pressing and holds the specific number. You can deselect everything by pressing and holding the X. This is an excellent game I would highly recommend! (Edited to add more info after more time and to change from 4 to 5 stars.)

this is a pretty beginner-friendly app, IMO, and the ability to turn off the timer for more relaxed gameplay is nice. the puzzles are tricky, but not so difficult that i get frustrated, and so far the paid puzzle packs have been worth their price. my only complaint is that it'd be nice to have a dark mode, since i haven't been able to find one so far and i tend to prefer to use apps on dark mode. the UI isn't eye-burningly bright, though.

Thank you for your feedback and yes, we plan to add dark mode in the future. We will do this as soon as we finish some other projects which we are currently working on.

This used to be my second favorite sudoku app, due to satisfying difficulty but hated the user interface. Then one day I thought I found a bug in the puzzle emailed the dev and he emailed me right back, so I told him my suggestion about the interface. Today I jumped on for the first time in a few weeks to learn he got the change deployed and the experience is even better than I expected, love it!!
