Russia will take on the U.S. in a grueling curling match on Friday in the Sochi.

Both teams haven’t had much luck in the Winter Olympics this year as they each only have one win. However, there’s still hope since the U.S. has five more games to make a comeback while Russia has four.

Yet, the competition is fierce. China leads with four wins and no losses, while Great Britain follows in second with four wins and one loss.

The idea of curling is to throw 40 pound granite stones from one end of the ice field to the other, which is the scoring area or the “house.” After a stone is thrown, two sweepers attempt to control how close it lands at the scoring area.

After each team throws eight stones, their score is determined by whose are closer to the “house.”

The sport made its debut as an Olympics Winter Sport in 1924 when Great Britain defeated Sweden and France. But, despite its long history, curling has received negative criticism from many who debate whether or not it should be considered a sport.

"I once had somebody come up to me and ask, 'What exactly is curdling?'" Rick Patzke, the chief operating officer of USA Curling, told the Los Angeles Times.
