How to play sudoku:
If you've never played sudoku or not aware what it is, it's a mental skill game that requires you to use logic and deduction skills to solve a grid of 9 x 9 tiles. Within that grid, each row, column, and 3 x 3 group will have only one occurance of the numbers of 1 to 9, thus our name "Count To Nine".
Because a number can only appear once in it's row, column, or group, it allows you the user to make deductions and assumptions of where the other numbers will be and what numbers they cannot be.
The candidate function allows you to enter the possible values of cell into the field so you don't forget some of the deductions you've already solved and gives you a visual reference to the other values in that row, column, or group.
This is truly a game for all ages and skill levels. We have five difficulty levels that will be fun or challenging for any level sudoku player from beginner to expert.
If you have any issues with the game, please contact us and we'll work to resolve any bugs or glitches. We're planning on adding more functions and features, so if you have any suggestions, please let us know and we'll try to accomodate them.
