Rebound (video game)
Development of "Rebound" began in late 1973, as one of several variations they produced in 1974 on the gameplay of the successful "Pong" (1972), Atari's first game and the fourth-ever arcade game. Around the same time, Atari launched Kee Games, a subsidiary meant to produce clone games of Atari's products and act as a competitor in order to expand into more distribution channels in the same region than the industry typically supported. Kee's first game, released in March 1974, was "Spike", a clone of "Rebound", which added a "spike" button to the game that made the paddle jump up and attempt to bounce the ball downwards instead of up. In addition to the base game, Atari sold a conversion kit to convert any Atari two-player "Pong" variant into "Rebound", and in 1977 "Rebound" was included in "Video Olympics" for the Atari 2600, a collection of "Pong" variants.
Tetris (Atari)
Tetris (styled TETЯIS) is a puzzle game developed by Atari Games and originally released for arcades in 1988. Based on Alexey Pajitnov's "Tetris", Atari's version features the same gameplay as the computer editions of the game, as players must stack differently shaped falling blocks to form and eliminate horizontal lines from the playing field. The game features several difficulty levels and two-player simultaneous play.
