This Fibonacci spiral jigsaw puzzle, by far, is the most stunning one I’ve ever seen. Like other normal jigsaw puzzles, this jigsaw puzzle has just one solution. However, unlike standard jigsaw puzzles, in which each piece has a unique shape and is roughly the same size, all of the pieces in this puzzle have the same shape but differ in size.
The arrangement of the parts follows the pattern seen, to mention just a few examples, in sunflowers, pine cones, and roses. This design is based on the Golden Angle, approximately 137.5 degrees. There are eight spirals in one direction of the puzzle, and in the other direction, there are thirteen.
The numbers 8 and 13 are part of the Fibonacci series, which is an additive sequence in which each number in the sequence is the sum of the two numbers that came before it in the sequence: 1, 1, 2, 3, 5, 8, 13, 21, 34, etc.
