Su Doku Spreadsheet Helper
Download this spreadsheet which will help you to solve your Su Doku puzzle.
On this spreadsheet you can enter the given numbers in the puzzle and then print out a A4 size paper with the given numbers and the full list of the possible numbers that can fit into each block. Don’t be fooled. This will not solve the Su Doku puzzle as you will still need to make some intelligent guesses. This will just eliminate annoying errors and give you more space to work with.
