The game of hockey has been played for over 4000 years in many ancient civilizations. It was originally known as a "ball and stick" game. The key priority in hockey is to protect the scoring area around the goal and keep opponents from taking shots. Players use sticks to pass and shoot the puck and many wear protective equipment like mouthguards, gloves, and shin pads. A regulation hockey rink has markings like lines and circles on the ice surface along with goals for scoring.
