Sudoku Classic & Killer

The game has been a great pastime for centuries. It helps increase your memory power and thus the brain power. In this particular version you should add the feature where by a incorrect number will not be accepted into a square not meant for it. Player immediately will try another number. Of course the error count can go up by one, that is fair! Hard to take note of the green and red background when the correct and incorrect fit occurs! Thank you. It is a fantastic game on the whole. A true blessing.

I like this Sudoku better than a previous one I had because of its many options. One problem I have is the blue is so dark I can’t see the numbers in the square.
