The easy sudoku puzzles will require nothing more complicated than simple singles and the occasional direct pointing method. These are easy to do just by scanning the grid and looking for lines to isolate a cell where a particular number can only go (hidden singles) or looking for cells where there is only one possibility left (naked singles and full houses).
Our mild to medium sudoku puzzles up the difficulty a notch by adding in moderate techniques like naked and hidden pairs, and pointing and claiming. These introduce you to the idea of elimination of possible options (or candidates) leaving you with the simple singles you find in the easy level. You may want to start thinking about writing candidates into the cells at this stage to help you spot and keep track of the candidates you eliminate.
Moving onto our hard sudoku puzzles level, we introduce some more advanced techniques for eliminating candidates such as triplets, wings (including the infamous X-Wing!) and a few of the easier fish, single digit patterns and simple colouring. You will need to write down candidates to spot these!
But we aren't going to stop there. For the real enthusiasts we have a fiendish and diabolical sudoku levels with the more complicated fish (some with fins!) and wings, and unique rectangle methods.
And for the masters of sudoku, our extreme and nightmare sudoku level will require the use of forcing chains! Hellishly difficult, but yet solvable using pure logic.
