Buy Toroidal Sudoku Puzzles

Toroidal Sudoku is one of the more unusual variants of sudoku out there, and may be unfamiliar to many. Therefore it is ideal if you are looking for a puzzle that is a little novel or different for your publication, and particularly if you are looking for something tricky as a competition puzzle - the unusual region shapes in a toroidal sudoku grid can make the puzzle hard for humans to solve.

Toroidal Sudoku The basics of toroidal sudoku are the same - the rows and columns must contain the numbers specified once and once only, but the twist is the standard box shapes are changed. This is akin to jigsaw sudoku, but toroidal sudoku takes it one dastardly step further: these regions can wrap around the top, bottom, left and right of the puzzle, and therefore a keen eye is required to solve this fun variant puzzle.

You can see in the image to the right that here there are nine coloured regions, and several of these wrap around the edges of the grid. For instance, the second and third squares in the grid are part of the region containing the given '2' in column one.

We use colour where available to help the eye distinguish the regions, but also use the thickness of the border to demarcate the regions. You'll notice that where regions wrap around the edge of the grid, there is no border in the direction of the wrap.

We supply 6x6 and 9x9 toroidal sudoku puzzles, in PDF format or another format if required. If you'd like to try before you buy, then here is a link where you can play the puzzle above online using our online toroidal sudoku player.

We can supply an order of toroidal sudoku any size with quick turnaround times and meet any bespoke requirements. All puzzles have a single solution that can be reached through logical rules alone, no guessing is ever required to solve our toroidal sudoku puzzles.
