There were almost 100 of them competitors.
Some of the categories included solving cubes while blindfolded or with the use of only one hand!
"There really isn't a trick. If you want to learn it, you just need patience. If you want to do it fast, you've got to practice a lot," said one of the "speed Cubers."
The top talent, who really wanted to show off their skills, competed with more unconventional looking Rubik's Cubes.
