It took me about 2min 20sec to completely solve my hand made ring-and-wire puzzle, which is not my Personal Best. This 9-interlocking-ring puzzle has an official name ----classic Chinese puzzle, or called jiulianhuan, which is in fact a binary system Math Game.This classic Chinese puzzle is made from stainless steel wire and iron rings, with 8th and 9th copper wire ring. This is not only an intelligence toy, but also an EQ game. Because it requires one's perseverance to overcome most of the mechanical puzzles.
