| For anyone trying to get into speedcubing, I'd recommend YouTube
| tutorials from channels like J Perm, especially his Beginner
| Method tutorial, which I found taught me much better than any
| written resources I was finding. He keeps the alg count lower at
| a slight cost to efficiency, but this makes memorizing it a lot
| easier, and you can still get solve time down to a minute or two
| after enough practice.
|
| For learning Roux method (my favorite), I found CriticalCubing's
| videos most helpful, though Kian Mansour is also quite popular,
| and SpeedCubeReview has some Roux videos as well.
|
| For the actual cube, check out which cubes under $15 are popular
| on speedcubeshop or an equivalent online store in your country. I
| haven't bought one in a few years, but the MoYu RS3M 2020 and
| 2021 were both quite good. I would recommend picking up the extra
| magnets to add in, and a bottle of cube lube (as silly as it
| sounds, it keeps things working well for longer, and you only
| need a few drops). Generally the Rubik's brand cubes are seen as
| worse than any modern Chinese cubes (patents expired a while
| back).

| Ideal Toys bought a few books too. I had both the ideal and the
| more popular top, middle bottom solution. I figured out how to
| reverse the corner flip move and w that one hack I can still do
| under a minute. The ideal is simple. Top minus one edge, bottom
| corners place, orient bottom corners. Fill the bottom and top
| edges, then the middle. Very few paterns. Yes not to most step
| efficient but way less to memorize. I figured out early to leave
| to speed cubing to the nerds. Being able to solve under a minute
| is enough to put you near the top of any social group.

| it).
|
| Later in college, having forgotten everything. I worked out the
| solution myself after a hint from a prof (that it's essentially
| conjugations of group elements).
|
| Years later, I again developed a solution, but this time I do
| edges first, with permutations that mess up the corners and
| then the corners. I mainly mixed it up to do something unique.

| Great collection. That crazy mouse on Jessica Fridrich's site is
| especially refreshing.
