I want to share a fun little hobby I have. I started solving a rubik's cube around 9 or 10 years ago, when I was 11-12 years old. My sister and I bougt a cheap cube in a dollar store and decided to try to solve it using some instructions we found online, this one(I still use some of these algorithms).
The beginners' method is:
Solving a white cross
Inserting white corners
Inserting edges into the middle layer
Solving yellow cross
Fixing the top edges
Moving corners in the right place
orienting the corners
A slightly more advanced method I use does steps 2 and 3 at once(these two steps usually take the longest), I average slightly less than a minute.
The pyraminx is one of the easiest puzzles and takes a few seconds to solve if you know how. You could even solve it by luck and a bit of messing around.
The larger cubes have a few more algorithms but if you're using the reduction method(solving centers, combining edges to make a 3x3 with long edges and bigger centers) you still need to know how to solve the 3x3 cube.
Even cubes have 2 extra algorithms for parity since they don't have centers. There's orientation and permutation parity:
The method for all big cubes is almost the same:Solve one center
Opposite center
A center in between
Adjacent center
Last two centers
Combine 4 edges by only slicing the middle layers and placing solved edges on top
Do the same on bottom
Solve last four with algorithms (there's one more algorithm for 5x5+ cubes that switches 2 opposite edge pieces)
Solve like a 3x3
(For even cubes do parity algs if necessary)
I like solving bigger cubes like 13x13 on my phone if I have some time to burn. I use a cool app called MagicPuzzlePro free on google play store.
Here's a video of me solving some(my first dTube video). I have a timer but it's on my phone with which I recorded.

Thanks for checking out the post. I'll upload more origami soon :)
