It would benefit greatly from a notes function like in normal sudoku. For the bigger puzzles, I have to grab a notepad to track what tiles have what possibilities. Definitely limits the playability of the game.

I'm sorry you had this experience, but please note that Hexakai does have a built-in notes function. You can access it by long pressing the cell you want to take notes on, then setting its pencil markings and colors as you see fit. If you have any further questions, please feel free to contact me via the app's contact page.

*Edit: after many attempts, it worked. Simple, relaxing game.* Doesn't work on this device. As soon as the game and Google Play sign-in loads, a white screen overlays everything else
