Avalanche - video game 1978
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 the Atari 8-bit family.
Gameplay
Avalanche is for 1 or 2 players, alternating turns. There are six rows of rocks at the top of the screen. The game starts with a six-storied platform and the player loses one platform per row of rocks cleared. The player scores points for those rocks they prevent from reaching the ground. The farther the row of rocks, the smaller and faster they become. The ultimate goal is to get enough points so that the player can continue the game should they lose their first one.
