About Air hockey is a game for two competing players trying to score points in the opposing player's goal using a table having a special low-friction playing surface. The mallet is gripped behind the knob using one's fingertips, not on top of it. This allows more wrist action and helps the player to move the mallet around the table faster. For basic defense, the mallet is kept centered at least 8 inches out from the goal. In this position, very slight movements to the left and right will block virtually all straight shots. To block bank shots, one pulls back quickly to the corners of the goal. This is known as the "triangle defense".Rules When the puck enters and drops inside a player's goal, the player's opponent receives one point. A player may hand serve the puck only after it has entered his goal. A player may play with only one mallet on the playing surface at one time. Violation results in a foul. The puck may be struck with any part of the mallet. When the puck is in contact with any part of the centerline, either player may strike the puck.
