This puzzle is one of my favorites. I had a store bought one and it was super fun to play with, until... I lost the pieces for the puzzle. So I said to myself, "What if I made a new one?"
Well that's what I did, and I will share it with you guys in the following steps.
But first, what is the goal of this amazing puzzle? Well, as shown in the picture, you have to get the main puzzle piece (which is the big red one) to the top-center position. There are some rules though. You can only slide the pieces on the board, and can not rotate them. You also cannot lift the puzzle pieces off the board to move them to a different position. Besides that, though, the puzzle is pretty straightforward.
Now, without any further interruptions, let's make this puzzle.
The base for the frame was made out of MDF wood. However, any thin wood would work. I cut the base to be 5" x 5". Next, make an outside rim for the base using wood that is around 3/4" thick. Now cut two of your strips of wood to be 1/2" wide and 5" long. Cut your other two strips to be 1/2" wide and 4" long.
Now it is time to glue your frame onto the base. Glue your pieces onto the outside of your base, and clamp them down onto the wood. Your finished frame should look like the one in picture 4.
