This beautiful puzzle is made from a high quality nickel plated wire. The thickness of the wire, which is only 3mm ensures a sturdy construction, but also makes it rather easy to manipulate. Your task is to separate the zero shape from the 3. The string is there just to make your job a little harder. The puzzle is a nice way to tackle your fear of the Big 30, and judging by its difficulty, you won’t have much to worry about. The golden string and dark red bead play a nice contrast with the silver finish of the frame for an overall stunning appearance. The Big 30 was designed by Allan Stein, the founder of PuzzleMaster and also the creator of our Slap Shot puzzle series, presented at the 32nd International Puzzle Party.
