Can You Solve The 7-Cent Logic Puzzle?
Can you solve the 7-cent logic puzzle? This problem requires not math, but is easiest to solve by experimenting with a drawn diagram and seven actual coins. You have a diagram with eight vacant circles arranged in a circle. In the center of this circle is network of straight lines: each vacant circle connects to two lines, and one of those lines connects to the circle on the right side of the circle straight across the network, and the other line from each circle connects to the circle on the left side of the circle straight across the network. You must place a coin on a vacant spot in the diagram and slide it along a line to another vacant spot. Do this with each coin until all but one of the spots are filled. Can you move all seven coins?
