Summarize this article in one sentence.
Each game of curling is played with 2 teams consisting of 4 players apiece. Team members take turns throwing stones. The turn order is determined before the game and is followed throughout it. The exception to this is in Mixed Doubles curling. Teams are composed of 1 male and 1 female player. Mixed Doubles games are much faster than regular games. The playing surface for curling is called a sheet. You stand at 1 end of the ice and aim for the “house,” which is the target at the other end. The “button” is the bullseye in the center of this target.  Many beginners are thrown off by the size and color of the blue, white, and red rings. Ignore the rings. They’re a visual indicator of where to aim, but otherwise don’t pay them much attention. The most important part is how close your stones are to the button.. Players will start from a position 57 ft (17 m) away from the house. To stay in play, the stones must stop between the hog line, which is 21 ft (6.4 m) from the button, and the back line behind the house. Each team plays by using granite stones, also called rocks. Teams alternate turns, throwing 1 stone at a time. Each team member gets to throw 2 stones total, which their teammates guide towards the house.  Each stone weighs about 42 lb (19 kg), so guiding it along the ice takes some practice. Team members alternate turns. You have to wait to throw your second stone In Mixed Doubles, each team gets only 5 stones. Think of an end as an inning in baseball. Once all the stones are thrown in an end, an official counts the score and writes it on a scorecard. Each team curls a total of 80 stones in a match.  Each end begins with the team who won the previous end. If Team B scores more points in the first end, they start the second end. This is fairer than it seems because the team that goes second in curling has an advantage. The amount of ends can change depending on the game format. Full-length games may be limited to 8 ends. Professional Mixed Doubles games are always 8 ends long, but recreational games may be even shorter.

Summary:
Form a team of 4 players who alternate shots. Aim for the target in the center of the ice. Send 8 total stones down the ice towards the house. Play 10 ends in a game.
