Ammonite Puzzle

Nervous System

The Ammonite puzzle proves that jigsaws don't need to have many pieces in order to provide a challenge. Based on a photograph of the ancient fossil, this shell-shaped puzzle contains 117 dendrite-style pieces that are laser cut from a custom birch plywood. Its unique spiral design means that instead of working from the exterior of the puzzle and moving inwards (as you would with standard puzzles), you have to follow the spiral as it coils inside. While you try to match up these intricate shapes, keep an eye out for two multipiece ammonite "whimsies" that are hidden inside the complex design. 

Pick up this spiral puzzle for yourself to test out your skills, or wrap it up as a gift for the jigsaw-enthusiast in your life.
