Solving A Rubik's Cube Using The Petrus Method
The Petrus Method is another way to solve a Rubik's Cube. It doesn't follow the traditional layer-by-layer method. I haven't mastered this method yet, but these videos have been helpful.
The Petrus Method was created by Lars Petrus. Lars used the Petrus Method to win the 1981 Swedish championships. In 1982 he finished 4th in the world and in 2005 he won the “fewest moves” world championship in Orlando, Florida.
The Petrus Method has seven steps. First is to create a 2x2x2 corner, then expand that square into a 2x2x3 rectangle, then twist the edges. Finally, finish the first 2 layers and move onto positioning the corners on the incomplete sides. When that is completed you move on to positioning edge pieces in their correct location. This may sound extremely confusing, but it’s all clearly explained in the tutorial videos.
The best way to master the Petrus Method is to get good at each step first, then put all the steps together to completely solve the Rubik’s cube in one sitting!
