The Delta puzzle is formed by joining three separate pieces that mesh with each other.
It is designed by the brain-child of Hong Kong native Kyoo Wong who, with the eye of an engineer, has worked on a number of cast puzzles.
While this puzzle is simple in form, its geometry somehow challenges and stirs up our creativity.
The theme is the number three.
