About Our Sudoku Puzzles

Welcome to our collection of expertly-crafted sudoku puzzles.

We don't just randomly generate and mass publish sudoku puzzles like many sites, apps and publishers do. Our sudoku puzzles are carefully devised to cover a wide spectrum of solving techniques, from the basic singles and pairs, through to the advanced techniques including wings and fish, and all the way to master-level forcing chains!

With ten levels of difficulty you will be sure to find something to challenge you, going far beyond what you would find in most publications, usually requiring nothing harder than pairs, pointing or claiming, even in their "expert" level puzzles.

All our grids are picked to be symmetrical and/or aesthetically pleasing, they are thoughtfully designed to incorporate certain select methods of solving in each puzzle, giving a wide diversity of difficulty and solving experience. They are accurately graded on the relative difficulty and number of solving techniques required.

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. This is about as hard as you'll find in most magazines and newspapers, even at their "expert" or "very hard" level.

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, unique rectangle methods and 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, loops, chains and almost locked sets.

And for the masters of sudoku, our extreme and nightmare sudoku level will require the use of forcing chains, nets and the Kraken Fish! Hellishly difficult, but yet solvable using pure logic.
