Avalanche is an arcade video game designed by Dennis Koble and released by Atari, Inc. in 1978. The object is to catch falling rocks with a controllable set of paddles that diminish in number and size as the rocks fall faster and faster. The concept gained a much wider audience after Activision released an unauthorized adaptation in 1981 as Kaboom! for the Atari 2600. The only official home port of Avalanche is for Atari 8-bit computers. In 2025 Atari announced a port for the 2600 and 7800 consoles.
