Daily Sudoku

Every day, there will be a new sudoku challenge waiting for you. Start by choosing what difficulty you want to play on. The more difficult you make it, the less numbers you get. There is a big square in front of you, with some numbers already filled in. Try to figure out what other numbers there could be on the screen. And remember: the numbers 1 through 9 need to be in the squares, and the same number can’t be in the same vertical and horizontal line.
