The classic sudoku puzzle
The novel variant that combines elements of kakuro and requires you to do some sums as well as use your logical brain
It's time to scramble those 3x3 boxes with this fun variation of the sudoku puzzle
Perhaps the most popular and common of the variants, here the X regions also must contain 1 - 9 uniquely giving this puzzle the real X-Factor as it were
An unusual puzzle, here you must work out whether certain cells are all odd or even so it certainly is a little different to the standard puzzle
Combines the elements of killer sudoku and sudoku X into one rather tricky puzzle
One of the hardest sudoku puzzle types for the human brain to comprehend, as some of the regions actually wrap around the top and bottom and left and right of the puzzle - therefore making it rather hard to keep track of which cells are in each region!
Here not only does the row, column and 3x3 box count as a region but also the position of the cell within each of the 3x3 boxes: a fun and colourful variant of the puzzle
We've added more boxes in this variant of the puzzle - four more in fact, so there are now a total of 13 9x9 regions to tackle, good luck!
The classic five grid samurai puzzle, which requires you to use information from overlapping puzzles to solve all five - requires a little time and patience but you should get there with persistence.
