Knockout is a board game released in 1991 for 2–8 players, 30 minutes per game, and ages 7 and up. Its main mechanics are Dice Rolling, Single Loser Game, and Physical Removal.
A wall made of rainbow-colored bricks. A vibrating motorized jackhammer. What could possibly go wrong? In Knockout, players take turns rolling the color die, selecting a matching brick, and carefully blasting it out with the buzzing Rammer Hammer. But there’s a twist—one of the bricks is the dreaded Knockout Block. If you knock it free, or if the whole wall comes tumbling down, you’re out! The remaining players rebuild the wall using the bricks you removed, and the last one standing wins. With no supporting frame and a steadily wobbling tower of rebalanced blocks, Knockout delivers satisfying tension and demolition glee. Knockout, Hold On Scooby-Doo!, Happy Feet Two: Hold on Erik, and Spider-Man: Spider Sense are all about removing bricks without toppling the structure—but each adds its own flavor. While the “Hold On” trio features perched characters and plastic frameworks, Knockout trades in cartoon mascots for pure demolition thrills with its unique battery-powered jackhammer and iconic “Knockout” brick that could spell your doom. Same tension. More vibration.
Knockout supports 2–8 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 Knockout 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 Knockout for ages 7 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.
Knockout 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.
Knockout belongs to these categories: Children's Game, Movies / TV / Radio theme, and Action / Dexterity. Its main mechanics are Dice Rolling, Single Loser Game, and Physical Removal. Categories describe the theme and setting of a game, while mechanics describe what players actually do on their turns. Each mechanic links to a catalogue hub with similar games, which helps when you want something comparable.
The catalogue lists Knockout as a base game. It can be played on its own with the components in the box and does not require any other title. Expansions, if any exist, add new content or rules on top of it and are listed separately in the catalogue with a link back to this base game.
