This is an interactive app to train an advanced solving method of Jessica Fridrich CFOP. The cube is automatically scrambled and partially pre-solved up to a certain stage, so that you solve not the whole cube, but just to complete the stage. Then you repeat it over and over again for how many times you want, until you learn the stage's selected algorithms, or until you get bored. If you are a beginner, you might want to start by learning just one algorithm. If you select only one algorithm, the cube will always be scrambled and partially pre-solved such, that you can solve the stage by using this algorithm. If you select and train one algorithm per day, then some day you will learn the whole CFOP method :) For each stage you can train the algorithms in the order presented, or you can opt-in to train them in random order. I.e. if several algorithms are selected, you can do something like "OLL-" or "PLL-attacks" either in sorted or in random order.
