"It has 6 independently turning sides, each with there own face color stickers. " This is a sloppy sentence.
"Its simple design, yet extremely complex challenge made it one of the biggest selling puzzle game in history." I think you need an extra comma.
"In 1979, the “Magic cube” was featured " Featured where?
"The puzzle has a rather simple mechanism." Is it?
"It has also been made lighter for safetey reasons. " Really? Were people dying due to cube/head trauma?
"Those who are faster at solving will usually use whats called a “Diy cube”." Capitlize DIY.
"The exact creator of diy cubes is unknown" DIY isn't an invention, it's just a business model where people can do it themselves.
"These cubes cannot be bought in in stores, and must be online. " You sure? Or is this a US-centric statement? Also, the Sudoku cubes were DIY and sold in stores.
"The most notable shop for Diy cubes online is CubeForYou.com" Umm...rubiks.com has DIY. I'm guessing they have more traffic that Cube4you.
"Those who have mastered the puzzle, and strive to get faster are called speedsolvers." Really? I thought they were speedcubers.
"Speedsolving is defined by those who do it as “Anyone who tries to solve the puzzle as fast as they possibly can.”. " Sloppy sentence.
"The community of speedsolvers is incredibly large, and world wide." Incredibly large? It's a few thousand people.
"All official competitions are goverened by the World Cubing Association." Nope.
"The most well known is the one taught by the book “You can do the cube”, called LBL." There are many techniques that are LBL. I'm guessing the method included with the cube itself is more well known.
