Extra Experiment Expansion is an expansion for Experiment released in 2009 for 3–6 players, 30 minutes per game, and ages 8 and up. It was designed by Sander Vernyns and Tim De Rycke and its main mechanics are Set Collection and Auction / Bidding.
E3 (Extra Experiment Expansion) is a very small expansion for Experiment. E3 introduces 3 new cards for the confidential lab cards deck, beakers with a combination of two secondary colours. These wildcards can be used to replace one of each of the beakers with a secondary colour of the original game to add some more variation (and more power to the confidential lab cards).
Extra Experiment Expansion supports 3–6 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 Extra Experiment Expansion 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 Extra Experiment Expansion 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.
Extra Experiment Expansion has a complexity rating of 1.0 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.
Extra Experiment Expansion belongs to these categories: Card Game, Bluffing, and Expansion for Base-game. Its main mechanics are Set Collection and Auction / Bidding.

The credited designers of Extra Experiment Expansion are: Sander Vernyns and Tim De Rycke.

The catalogue lists Extra Experiment Expansion as an expansion for Experiment. Expansions add new content, rules or scenarios to the base game and usually cannot be played on their own, so you need Experiment to use it. Check that your edition of Experiment is compatible, as some expansions were revised between editions.
