I won&#x27;t even begin to discuss how horrible of a scam this stuff is. I will speak to the Rubik&#x27;s cube for a moment though. First off, we know that a Rubik&#x27;s cube has 43.25 Quintillion possible starting combinations. Any one of these combinations can be solved in 20 moves or less (we know this from a team of researchers who used a super computer to calculate all of the possible moves). So while you could memorize a set of musical cords for each possibility, it would be an insane number of things to memorize. Interesting scam premise though.<p>At any rate, learning to solve the cube is actually a very enjoyable and relaxing activity that I believe helps my brain, at the very least. There are a number of systems for solving the cube. I use CFOP. With it I can solve any cube in under 30 seconds. Much of it is intuitive with the memorization about 100 algorithms (technically there are 119 total: 41 for the f2l, 57 oll&#x27;s, and 21 pll&#x27;s. I use all of the oll&#x27;s and pll&#x27;s and only a few of the f2l&#x27;s. I mostly finish the f2l by intuition). Don&#x27;t get tricked into buying some neat system for the cube. Ask the experts. You can get all of the algorithms for free online for numerous systems. Grab a cube and just have fun!
