No-Frills Sudoku

Maybe you should add some options: when I play sudoku and I'm not certain of some numbers I write a small number on a square corner, just as a remainder, maybe you should add some option to do that with different colours or underlined numbers

wtf how do i put something other than a one????

I really like the gameplay, format, and the colors. I just wish the numbers were a little bit easier to read. The black blends in a little bit too much to the gorgeous dark blue background, particularly in some areas with the monkey pattern behind it.

Too bad the hard levels are not real Sudoku. They have multiple solutions.

i cant type one number with that distracting background :<
