About a year ago I picked up this fun toy called the Mind Jewel from a local games shop. The toy consists of twelve pentagons strung together on an elastic band. The aim is to arrange the pentagons to make a complete dodecahedron. The task is made challenging because the design of the pentagons prevents the puzzler from taking certain paths. You may be left with the Blob or the Turtle and be unable to fit the remaining pieces. The puzzle has a solution!
