To play Retro Ping Pong, use the arrow keys to move your paddle. In two-player mode, the player on the left can move their paddle with the W and S keys. The goal is to score 7 points to win the game. There is also an action mode with special rules that change the way the game is played, such as a ring of fire in the center of the field, multiple balls on the field, a layer of fog down the middle of the court, gravitational voids, bumpers on the court, and blasters that players can use to hit each other. To improve your skills, try to anticipate the direction of the ball, play with a friend, and get a feel for different patterns in the game.
