The allure of the Cast Puzzle….
The Cast puzzles have both a challenge and a difficulty level element that wire puzzles, generally known as “disentanglement puzzles”, don’t have. People who try them experience refreshing stimulation as no force is necessary and this arouses their interest in solving them.
The Cast Puzzles offer an unlimited amount of mystery. Its collectability is also one of its appeals. Once you solve one, you will no doubt want to challenge yourself by solving more.
There are no answers in the set so as to allow you to solve the puzzles on your own and experience real fulfillment.

Take it apart and put it back together, that is the objective of this great metal puzzle. A word from the designer: “After completion of this puzzle by Dutch designer, Oskar, the words ‘key’ and ‘ring’ should be properly lined up with each other. This is vital. If you try to put the pieces back together without lining up the words correctly, you will have failed even after achieving what appears at first to be a successful matching. It should read ‘Key Ring’ even when upside down. The wording design is courtesy of the prodigy, Scott Kim. The key word is ‘pair’ “
