Concentration is a board game released in 1958 for 2–5 players, 30 minutes per game, and ages 10 and up. It was designed by Jim O'Connor and its main mechanics are Set Collection and Memory.
A rebus puzzle is covered by matching pairs of items. The items are covered by numbered slides. The slides are numbered one through thirty in the Milton Bradley editions and one through twenty-five in all other editions. each player or team chooses two numbered slides and reveal whatever items are beneath the slides. If the items match, then the items are removed to reveal parts of the rebus puzzle of which the team may hazard a guess. Solve the rebus puzzle and receive the value of all matching pairs possessed in play money. The side that has more money after three rebuses wins. Puzzles in the Milton Bradley and Endless Games editions were designed by the people who created them for the series: Norman Blumenthal for the former and Steve Ryan for the latter. Educational Concentration is made for classroom drills. It does not feature a rebus puzzle but it does have a plastic molded gameboard with twenty slots. The game comes with color matching, American history, American geography and homophone drills. More drills can be homemade easily. Based on the long-running television series which was inspired by the children's card game.
Concentration supports 2–5 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 Concentration 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 Concentration for ages 10 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.
Concentration has a complexity rating of 1.6 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.
