I 'd never touched the toy. It seemed like a mundane, boring, show-off action. Recently an aunt of mine got herself to solve it, so she bought one. She failed in trial and error, so I decided to give it a try. Child of the 00s as I am, I googled for the algorithm and sure enough it popped up. It took me about half an hour to understand it and a day to memorize it. Now knowing how to solve the puzzle, I must admit that it gives a sense of content each time you solve it. It's like reciting a short poem or a song or a gymnastic exercise. Isn't life weird?
