Tired of the same old sudoku? Sit & Solve Tight Fit Sudoku goes where no sudoku has gone before! Instead of putting one number in every square, some contain two (those boxes are separated with a slash), and the only new rule is: the number below the slash is larger than the one above. Even though the same "1-9 in every row, column, and outlined area" rule remains unchanged, you"ll never think of sudoku the same old way again!
