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.

Four pieces of the same shape are loosely interlocked together to make up this puzzle. All of the pieces fit loosely and it seems as though they would be easy to take apart.

However, one is soon at a loss and the puzzle gives no hint on how it can be separated. Another fantastic cast metal puzzle from Hanayama.
