Great looking, sleek Sudok with no ads. The difficulties in this game are harder than in other games, at least in my experience, as I actually had to learn some more advanced Sudoku tactics to solve a board. 5/5 with one minor complaint/feature suggestion: After filling in notes on the board and then writing a number, the notes that cannot be true anymore are not automatically removed. While this is not a necessary feature, it would be nice if this was implemented.

After completing a game, the timer continues to advance instead of stopping and automatically displaying a new game to start. Does not keep track of the best time to complete the game. What can you expect; the game is free. Okay, otherwise. UPDATE(8/9/2025) Sometimes the game's timer will stop once completed, but not always. Still need to fix this bug, but the game is free and definitely has NO ads.

First impression. Not as slick as the one I'm trying to replace. May take a bit of getting used to. Definitely needs option to add pencilled in possible solutions (oh apparently that is "notes"). Ability to colour in order to check "simple colouring" solutions would help too. Overall, I'm not overly keen on the UI. This is ridiculous. Not only are notes not highlighted as appropriate when a cell is chosen; if you have to leave the game for a short while they ALL get DELETED !!!!!
