Avalanche is an arcade video game designed by Dennis Koble and released by Atari, Inc. in 1978.

[3] The concept gained a much wider audience after Activision released an unauthorized adaptation in 1981 as Kaboom!

According to the manual for the Atari home computer version, Avalanche started out as a game about eggs and baskets called Catch.

Avalanche is housed in a custom cabinet that includes two large lit start buttons and a rotary controller.

The circuit board is based on the 6502 CPU, with game code stored in multiple ROMs.
