This was a gift for my dad's birthday, and probably my most intricate woodworking creation to date. I wanted to make some kind of sudoku-related object for him, and became inspired by pictures I saw of color-based sudoku boards online such as this one. I figured creating my own version would be a fun project and make the gift more personalized. I also set out to make some improvements to the models I saw.

Mine has storage for tokens to mark givens (corners cut), guesses (solid squares), and possibilities (tiny cubes). I also chose rainbow colors so that it's possible to recite them in order when checking which are missing. I no longer have the measurements of the individual parts, but hopefully these pictures might inspire people to create their own projects!

The materials I used were:
  • Oak boards for the sides and drawer walls
  • Four sheets of thin plywood - two for the top, one for the drawer bottom, and one thicker one for the bottom of the whole board
  • Acrylic paints
  • Acrylic clear coat spray (for the game pieces)
  • 2-in-1 polyurethane and stain for the board

As far as tools:
  • Laser cutter for the pieces and their slots
  • Woodworking shop machinery (scroll saw, table saw, miter saw, disc sander, two metric tons of sandpaper)

Step 1: Cut main pieces, dry fit

Again I don't have the measurements, but the general plan was to have a large box for the main board and a drawer that fit inside.

The size of the playing surface was constrained by the sizes of the holes for the pieces and the spaces between rows and 3x3 squares. The pieces needed to be slightly smaller than the playing holes, and stored within the drawer. A lot of figuring went into making sure that everything would fit properly. Buy extra wood so that you have some degrees of freedom everywhere possible.

In the first picture on the right you can see the four outer sides with dadoes cut for the top playing surface and the bottom thicker plywood (with a lip to hold it in). In the center are the four smaller drawer sides with dadoes for the drawer bottom. Beneath them are the four sheets of plywood. Not pictured are the plywood pieces used for creating sections in the drawer, and the plywood used to cut the playing pieces out of.

The second picture shows a dry fit of the drawer and main board. You can see how there are two plywood sheets on top - one will have holes laser cut for the pieces, while the other will provide a backing. I had to cut a hole in the front board to allow the drawer through, and this was accomplished with a drill and scroll saw.
Oh my gosh! Fanciest. Sudoku. Game. Ever. Do you have the laser cutting files you used?
Thank you! I was actually able to recover the file from my email, here it is:&nbsp;http://www.filedropper.com/sudokusquarelaser<br> <br> Let me know if you have trouble accessing it!
PS Here's the board layout as well: http://www.filedropper.com/sudokuboard
<p>thanks for this great sudoku.</p><p>I have trouble accessing the files, both of them. I guess they are deleted.</p><p>Could you please re-upload or attach it to the topic?</p><p>Thanks</p>
I have a lot of issues with number sudoku so this is AMAZING!
very nice. you have done a top job. very in pressed. can you please explain all the different pieces and how they are played. i think i get it but, would like to check. thanks.
Thank you! The big pieces are interchangeable depending on your preference, but one type is used to mark colors given by the puzzle which you know are correct. The other type is used to mark your guesses as you try to solve it. The smaller pieces are used to mark possibilities - say you conclude that a square must be either green, blue or yellow. If you want, you can put one of each of those colors into the square to remember that.
Coolest Sudoku I've ever seen! you definitely have my vote :)
Nice project! <br>
