Pong

Pong is an arcade sports video game designed by Allan Alcorn, as a training exercise assigned to him by Atari Inc. co-founder Nolan Bushnell, but Bushnell and Atari co-founder Ted Dabney were surprised by the quality of Alcorn's work and decided to manufacture the game. It is the first commercially successful video game, and it helped to establish the video game industry along with the Magnavox Odyssey.

Gameplay
The game is based on the sport discipline of table tennis, where you have to hit the ball with a paddle, hitting an empty competitor's field.

Why It Rocks

 * 1) It is one of the first games in history to not only achieve incredible success, building the video game industry and spreading game development, alongside with the company Atari Inc., and the first generation console Magnavox Odyssey, but also because of how the developers made good money from the game, which meant that Atari produced a lot of new games, not only on arcade machines, but later also on consoles that they developed, with the first console being the Atari 2600.
 * 2) The gameplay is surprisingly addictive for one of the first games in history to be released on arcade machines, although it may seem primitive nowadays, but it is still worth admiring Atari for creating this game, which, however strongly influenced the beginning of the video game industry. It is table tennis in the form of a video game, in which the rule is very simple, because it consists in shooting at the opponent's empty field, only in the form of a two-dimensional game.
 * 3) * As one of the earliest arcade games, it repeats itself endlessly, which makes the game has more replay value.
 * 4) * In order for Pong not to seem too empty, it has, as befits table tennis, at least eleven rounds, although it depends how many points you and your competitor have, by bouncing the ball into your or opponent's empty field. At most, the game has twenty-one rounds.
 * 5) As fun as it may seem, this game was actually not the easiest one, as not only does the paddle seem too fast to control, but the ball is also fast, especially when bouncing the ball with a paddle crookedly. All this makes this game not boring, but more interesting, as it could have been a bit demanding to some extent.
 * 6) The controls are not only simple, but also very easy to learn, which makes the game fun and you won't feel frustrated once. The only way you will control the paddle is by moving it up and down. To have a chance to bounce the ball, as befits Pong, move the paddle to the side where the ball will be in a moment, which will be quickly bounced to the opposite side.
 * 7) As for 1972, although the graphics and sounds are very simple, featuring the black screen with white border, paddle, ball (which in fact looks like a square), and bit-sounding sound effect, it gives the impression that the video and sounds have been transferred to the screen where you see on your TV or arcade machine. It could also make an impression that in those days, apart from looking at the screen, you had any ability to control anything you saw on the screen, specifically the in-game paddle, when it comes to Pong.
 * 8) After winning or losing 11-to-21 rounds, the paddles will disappear and the ball will bounce around the screen by itself, making the end screen look fun.

Bad Qualities

 * 1) No music, though understandable for the time, is kinda a drawback.
 * 2) There is also no colour in the arcade version. This was fixed on Home Pong systems.
