Sudoku - Killer Samurai Sudoku

What is Sudoku?

Sudoku is a Number Puzzle that requires no mathematical knowledge. (no adding or multiplication). It is based upon Japanese style crosswords where you are required to use logic to place numbers onto a 9x9 grid.

Rules

To solve the puzzle you must make sure that every column, row and 3x3 box contains the numbers 1 through to 9.
Almost all of the puzzles can be solved using logic alone and there is no need to guess. A puzzle can take from 20 minutes to 2 hours to complete depending on its level and your experience.
People have developed a range of methods and tactics in order to solve the puzzles.

Killer Samurai Sudoku Rules

Killer Samurai is an advance variation of Sudoku. Before undertaking a Killer Samurai Puzzle it is very advisable to have a go at solving a Killer Sudoku puzzle as Killer Samurai is almost identical to killer sudoku except it comprises of 5 interlocking killer sudoku grids. If you can solve a killer sudoku puzzle then there is a good chance you can solve these puzzles. As a quick review the rules are as followed:

In each coloured area there is a small number. This represents the total of all the numbers in that coloured area. To solve the puzzle you must make sure that every column, row and every 3x3 box in each larger 9x9 grid contains the numbers 1 through to 9.

A few tips to bear in mind: Remember that there is often a limited combinations for each area. For instance if there are two cells in a coloured area that total up to 5 then there is only two combinations. That of 1 and 4 or 2 and 3. The other tip which is very useful for starting a puzzle is to remember that each 3x3 area totals up to 45. This means that if all the coloured groups are all contained in a 3x3 area except for 1 square. Then that square can be worked out. Because if you total those coloured areas and then minus 45 then you will have calculated the value that must go in the square sticking out of the 3x3 area. (Hopefully I will be able to write some tutorials on solving a Killer Samurai Puzzle soon.)

The puzzles above are in colour as it makes it easier to recognise the coloured cage areas. However, I appreciate the problems with printing in colour. So for those without access to colour printers I have produced a black and white version.

At the moment only one of the puzzles is available as black and white as this is just a trial. I welcome your feedback on this puzzle below.

My sister and I both LOVE killer sudoku and we are so excited to find killer samurai puzzles on this site. I have only a black laser printer at the current time so I really appreciated that #10 can be printed in black and white. My suggestion is to make all of these wonderful puzzles available either in color or not.
