A Study on Solving Method of Chinese Ring
The Chinese ring is known as one of the difficult puzzles. We actually handmade this Chinese ring, examined the difficult reasons and found the following two main factors. First, it was to be two choices for "the first step". If it made a mistake in this first step, it indicated that it was a failure after many steps. Next, even if the "series of movements" of the solution was understood, it showed that confusion occurs on the way due to a huge number of steps. Furthermore, in order to understand the difficult factors, from the view-point of engineering, proposed a method to solve the Chinese ring. The method to visually organize using Excel was introduced. Also, the relationship between the number of links and the number of steps was intro-duced by a mathematical formula.
