Erno Rubik was invited to kick off the opening ceremonies (so I got a few pictures of him, woo hoo!). There was only one cube-related puzzle in the competition, however. Contestants were given a picture of an unsolved Rubik's Cube and asked to identify the center face colors on the unseen three faces. Perhaps not too challenging (although I'm sure many will find problem 3 difficult to do without pencil and paper). You can find the puzzles at http://www.rubiks.com/ or the specific URLs: http://www.rubiks.com/puzzles.html?p=rubiks_cube&q=1 http://www.rubiks.com/puzzles.html?p=rubiks_cube&q=2 http://www.rubiks.com/puzzles.html?p=rubiks_cube&q=3 If you think these puzzles are too easy, I have an added question for you -- what is the minimum number of moves needed to get a solved cube into the states depicted by the three problems? You will find problem 1 easy, problem 2 intermediate, and problem 3 difficult. -- Wei-Hwa Huang, whuang@ugcs.caltech.edu, http://www.ugcs.caltech.edu/~whuang/ --------------------------------------------------------------------------- "Everyone is trying to CYA their butt!" -- my supervisor [ Moderator's note: In case some of our subscribers don't know, I will supersede Wei-Hwa Huang's modesty to mention that he took first place at the World Puzzle Championship (for the fourth time!)]
