• Jigsaw Sudoku is variation of classic sudoku where the 3x3 blocks are no longer square, instead it’s irregular region of 9 cells, and all numbers from 1 to 9 must be fit inside with no repetition in any row or column or region. As twisted as it sounds, these puzzles are challenging and addictive.
• The Centre-Dot Jigsaw Sudoku puzzle has an extra block consists of the centre cells of the nine regions. The centre dots or cells are shaded and all sudoku rules apply i.e. no repletion in any row or column or block.                                                              
• Even odd is a variation where clues are given in the form of circles and squares. The cells that have circles need to be filled in with an odd number. While the cells that have squares needed to be filled in with even number. Of course, all sudoku rules must be followed i.e. no repletion in any row or column or block.
• The Asterisk Jigsaw Sudoku puzzle has an extra block formed from nine scatted cells (if connected they will form an Asterisk). The 9 Asterisk cells must be filled with the numbers 1 to 9 with no repetition. The cells are shaded and all sudoku rules apply i.e. no repletion in any row or column or block.
• Greater than Jigsaw Sudoku is a very challenging and twisted Sudoku where the signs > (greater than) and < (less than) are shown to guide you to fill the grid with numbers from 1 to 9. Of course, all Sudoku rules applied. The trick to solve greater than sudoku puzzles is to know all the possible candidates for each cell and use elimination to solve the puzzle. Greater than Sudoku is hard to solve (even the easy level) but not impossible to crack its code.

• XV Jigsaw Sudoku is an easy but fun sudoku variation where the neighbour cells that add up to 5 have Roman five (v) in between. And the neighbour cells that add up to 10 have Roman ten (X) in between. This variation is a fun and relaxing stretch for your brain.
• Samurai Jigsaw Sudoku has five overlapping 9x9 grid. Each row, column, and irregular block (surrounded by bold lines) contain all numbers from 1 to 9 (no number is repeated in any row or column or block). The key to solve the Samurai Sudoku is to use the clues from one grid to solve another.
