Sudoku Classic

doesn't end when sudoku is finished, and doesn't check for results.

it's pretty bad the has only 3 difficulties and it allows you to erase/replace the original numbers meaning you could accidentally erase an original number making the sudoku impossible to complete the graphic design can be improved on a lot.I really like the simplicity of the game and that's why I bought it also it doesn't collect data neither does it sell it to advertisers and it's offline the size of the game could be smaller as 80MB is quite big for the simplicity. EDIT: unsolvable sudoku XD

The puzzle generation is broken. I encountered a 'Hard' level puzzle where the default, pre-filled numbers violated basic Sudoku rules (e.g., repeating the same number in a single column). Since the starting board is mathematically impossible to solve.
