The Fun Theory

This is a special box for collecting used batteries. You can put one normal battery of any kind into the "start" hole, then the game begins. When you roll the handle, the maze plate revolves. You just need to find the the right way to exit for your battery as soon as possible. A record of the least time will be shown on the top. Through this amazing Battery Maze, people would like to collect used batteries spontaneously. Submitted by Golden Guo
