More decorative than a paper chain and certainly more fun that a chain gang, Chain is a work of patience and finesse. This puzzle is unique, as it can be solved in three different ways, depending on which piece is chosen for the middle. Our hint: a chain is only as strong as its weakest link. Designed by Oskar van Deventer. Each of these beautiful dexterity puzzles is made of intricately molded zinc alloy and features bright, brushed, or antiqued finishes. They make classy, eye-catching, desktop accessories as well as challenging diversions. Levels of difficulty are clearly marked: Level 1 - Easy, Level 2 - Fairly Easy, Level 3 - Moderate, Level 4 - Challenging, Level 5 - Difficult, and Level 6 - Very Difficult. The included booklet illustrates the challenge for each puzzle in the series, but please note that solutions are not provided in order for you to experience the "fun" and "agony" of solving these puzzles.
