The Delta Puzzle is formed by three separate, metal pieces that mesh together into a triangle shape. The first challenge is how to separate the parts, and then the puzzler must reassemble the structure. Triangles are a central theme here, and may help you find the solution! This puzzle is the brainchild of Hong Kong native Kyoo Wong, who discovered Hanayama (as a puzzle solver) more than 20 years ago and turned his puzzling interest into a job. An inspirational story for sure, you never know who might find themselves designing puzzles someday, maybe even you!
