## 25.1 SQ Ep 041 – Samurai Sudoku Quilt

April 22, 2012**Classic Sudoku and Quilts**

You ever heard of a Sudoku quilt before?

Sudoku is a puzzle game, much in the style of magic square type of math game.

Each section of the Sudoku puzzle is it’s own little nine patch, (a 3 x 3 grid) with each box of the nine patch has a number from 1 to 9 in it.

There are traditionally nine sections in a Sudoku puzzle, each section is laid out in it’s own nine patch box. A 3 x 3 grid of sections.

Traditionally, the rule for the puzzle is as follows.

Each box in each section has a number 1-9, with no repeats.

Each box in each row (of three sections) has a number 1-9, with no repeats.

Each box in each column (of three sections) has a number 1-9, with no repeats.

Here is a picture of a printed Sudoku puzzle that is not filled out.

You can easily see the shape of the traditional (classic) sudoku pattern as a series of three nine patch blocks in three rows. A nine patch of nine patches. (fractal for those of us math nerds)

You can see some designs in how and which numbers are included with the puzzle as well.

Well, a while ago, some quilter got it in his/her head that we could use these puzzles easily in quilts. Quilts are squares, Sudoku puzzles are squares, nine patches look like Sudoku boxes.

And I’ve seen a couple of people use fabric or colors to symbolize each number.

If each of the numbers is represented by a specific color OR a specific fabric, then this turns into a very easy (just have a design wall) quilt to make. Straight stitches, nine patches. You can include sashing around the nine patches to signify the darker lines.

This quilt takes 9 of the same colors or fabrics, so you may be able to use 9 fat quarters or 9 fat eights to complete depending on the size of the quilt you want to make.

And you should be able to find Sudoku quilt patterns to purchase if you do not want to actually do the puzzle yourself. Or ask your kids (or other recipient) to do the puzzle and then give it back to you completed, and then you make a surprise quilt, including the picture of the original puzzle on the back.

**Sudoku Quilt Variations Using Classic Sudoku Patterns**

If you wanted to be a little different, what about setting the Sudoku quilt patches in attic windows to designate the quilt blocks?

Don’t want to do the whole puzzle? Just make the starting numbers and leave the rest blank!

Or go ahead and give them the actual numbers using applique with the method of your choice.

Here’s a link to 21 different ideas with Sudoku quilts and art!

**Super Sudoku Quilts Using More Complicated Sudoku-Based Puzzles**

- Samurai Sudoku

Samurai Sudoku is a set of 5 Sudoku puzzles superimposed onto each other.

There are 5 puzzles next to each other that overlap in four areas.

The image below I haven’t put the time into getting the correct colors into the correct locations, but this is just an image that shows how the Samurai Sudoku quilt would appear.

If you’re having a hard time finding the overlapping sections, you could always use sashing colors to designate the different puzzles.

To get your own puzzle, you can look at samurai-sudoku.com Just look through the archive until you find an easy pattern and try it on your own. You can always download the solutions.

Also another good Sudoku reference for puzzles of all kinds (including the original and the next ones) that you can print the incomplete puzzle or the solution to the puzzle.

For making a quilt of this kind, you need 41 of the same colors for the blocks for this quilt.

If we use 2 inches finished as the size of your squares inside the block, then the quilt pictured above is 55 by 55, or if you use charm pack sized squares 4 inch finished square then the quilt can be 97 inches square.

It’s easier to upsize and downsize this quilt since it’s so simple!

- Nonomino Puzzles

Nonomino puzzle is like Sudoku in that there are still rules of Sudoku, such as only one of each number for each row, and then one of each number for each column.

The difference is that instead of a ‘nine patch block’ shape, the blocks are irregular shaped. There are still 1-9 numbers in each block that don’t repeat.

Here is a nonomino puzzle with sashing designating the different groups available for sets of numbers 1-9.

And if I would only do the starting squares on this puzzle instead of filling it all in it would look like this:

Here’s a general sudoku puzzle site that has many variations of sudoku including nonomino and samurai styles of sudoku to try, print, and save.

Darla, I’ve never heard of the nonomino puzzles, I’ll have to give them a try. I like Ken-Ken puzzles too, but I challenge you to figure out a way to turn them into a quilt. Maybe just having the clues appliqued in the blocks?

by dtwinter April 22, 2012 at 11:10 amVery interesting Darla. I had never heard of Samurai Sudoku or Nonomino. Thanks for the interesting podcast.
