LOUISVILLE, Ky. (WDRB) -- Some of the fastest fingers around spent Sunday in Louisville trying to unscramble cubes in record time. 

The World Cube Association hosted a competition at the Founders Union Building. Competitors tried to solve various sized cubes as quickly as possible for over 10 hours. 

Each competitor brought their own cube, which was given to volunteers who created computer-generated scrambles so everyone got the same puzzle.

Many of the competitors say they got their start watching videos on YouTube. 

"So I looked up a tutorial and I found one and I started," Henry Crawford said. "I learned most of it and I gave up. I found another tutorial and I learned that one and I went from there."

Some of Sunday's competitors solved the cube in less than 20 seconds. 

The current world record is 4.2 seconds.
