Game Description:Sudoku's objective consists in filling a 9x9 square grid, divided into 3x3 sub-grids with some of the squares already filled-in with numbers ranging from 1 to 9. A number must never be repeated in one same row, column or sub-grid. A properly executed Sudoku only has one solution. The problem can only be resolved with patience and logical skills, although no mathematical calculations are necessary. Sudoku puzzles are compulsive, challenging and demanding. In SudokuManía you can also play against the clock, beating your own record.
