Sudoku Tips

For the beginner Sudoku player, here are some tips to get you started:

Last Digit / Full House involves simply counting all the different numbers in a row, column and box that are related to one particular cell.

If there is only one number missing, then that is the number to place in the cell.

Hidden Singles are cells that have only one possible digit available when scanning it's related row, column and box.

It involves scanning the rows, columns and box in order to determine where a specific number can be in a given house/region, keeping the unique number rule in mind.
