Sharpen your mind with one of the most popular puzzle games! Featuring new puzzles every day, New Daily Sudoku will improve your memory, problem-solving skills, and it is extremely fun! All you need to do is to place numbers in the 9x9 grid to fill each column, row, and 3x3 grid with numbers 1 to 9. You can't place a number twice in a row, column, and 3x3 grid, so think carefully and try to figure it out. If things are way too easy for you, you can adjust the difficulty. From the calendar, you can pick previous days and play those puzzles too!
