At the 13th gathering for (Martin) Gardner my gift exchange was a set of 13 pieces that can be assembled into many shapes in many ways.
For this project I wanted to design a complete set puzzle with 13 pieces (to match the number 13 of the conference). It turned out that complete set puzzles with 13 pieces are very rare. I found precisely one; so that is the one I used.
At G4G13 I was also allowed to present this project in a 5-minute presentation which is now available on youtube. When that happens I will update this page with a link to that movie.

|This solution is one of the 12 that have congruent holes; these holes are shown in light Violet.|
|Sample solution for the kite shape.|
The catch with this puzzle is that, in order to fill the given outline, you will have to leave a hole in the shape of two connected tabs, shown in Violet. Simple counting of the number of tabs and slots needed to fill this outline should have informed the observant puzzler. If you wasted a lot of time not knowing this, you will now probably hate me. Get over it.
|Sample solution for the oval shape.|
The catch with this puzzle is the same as with the kite shape. You were warned.
|Sample solution for the hardest shape.|
The catch with this puzzle is the same as with the kite and the oval shapes. You should not ignore warnings from puzzlers.
The double tab hole appears at the same place for all five solutions.
