3 Pieces 9 Symmetric Shapes

I'm sharing some decent Symmetry Puzzles. I will try my best to present them to you.

Recently I've uploaded Symm-Aster Puzzle , which reminds me of a very very similar puzzle:

3 Pieces 9 Symmetric Shapes

Designer: Emrehan Halici

Goal: The title pretty much explained everything. Provided 3 pieces, use them all to make a symmetric shape. There are 9 solutions, try to find all of them!

Note: You may ask, isn't this just Symm-Aster Puzzle without the stars? The answer is a solid “NO”. They do look like each other, but I assure you the underlying structure is totally different. Besides if it is really Symm-Aster without stars, it would have more than 9 solutions!

What is Symmetry Puzzle

Symmetry Puzzle is somewhat similar to Tangram. But contrary to Tangram which dates back to hundreds of years ago, the first symmetry puzzle occurs just in this century. The goal of a Symmetry Puzzle is to arrange all the pieces to form a symmetrical shape, any shape is accepted as long as it has symmetry. The solution is often bizarre and hard to find, sometimes you don't even know you get the right shape by failing to recognize its symmetry.

I like Symmetry Puzzles, I especially like 3D printing them. Symmetry Puzzles don't require a packing tray or board (which usually consumes more filaments than pieces), and usually consist of only a few pieces, which makes them very efficient to print. Considering relatively long solving time, Symmetry Puzzles definitely worth printing.

- Symmetry Puzzles are hard, the more the pieces the harder the puzzle become. It's common to take a long time to fully solve a 3-Piece Symmetry Puzzle, and even 2 pieces can make a good puzzle. - And yes, there's even 1-piece Symmetry Puzzle that is available to print for yourself. Your task is to determine whether that piece has symmetry, and in case it has, explain what symmetry? - No packing tray not only save filament cost, it also get rid of worry about tolerance. Tolerance is crucial for most other mechanical puzzles, but tolerance varies for everybody. More often than not when I 3D print a puzzle with packing box or tray, it's either too tight that pieces can't fit in or too loose that I thought I solved it but what I found actually can't work if tolerance is right. - No tolerance worry also give you freedom to scale a Symmetry Puzzle to any size, be it last meter saver or big ornament… - Some Symmetry Puzzles have multiple challenges / solutions, so print once and enjoy multiple aha moments. In this situation, some challenges are often less difficult, while finding all solutions remain a big challenge. These puzzles are suitable for every player of any puzzle skill level.

Happy Printing & Happy Puzzling Forever!
