Avalanche is a board game released in 1965 for 2–6 players, 30 minutes per game, and ages 8 and up. It was designed by Frank W. Sinden.
Players take turns dropping their marbles down the channels of the game, trying to get as many marbles as possible to fall out the bottom. Impeding the motion of the marbles are several plastic gates. The gates catch the first marble that hits their top (subsequent marbles roll off) and swing back and forth when a marble hits their base. Using logic, players deduce which way the gates will move when they drop their marble, and try to make a move that results in the most marbles making it to the bottom of the game (or that blocks a potentially good move by their opponent).
Avalanche supports 2–6 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Avalanche is 30 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Avalanche for ages 8 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Avalanche has a complexity rating of 1.2 out of 5 from BoardGameGeek players, which makes it a light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
