Irrational Game is a board game released in 2016 for 1–5 players, 20–60 minutes per game, and ages 15 and up. It was designed by Dan Ariely.
A thought provoking, engaging and fun way to incorporate social sciences and human behavior into a challenging and strategic game. Dan Ariely's Irrational Game lets players draw question cards that describe unique and unusual social science experiments - players win if they correctly predict the results. The Irrational Game includes numerous question cards that showcase human behavioral experiments in various categories, but predicting the results of these experiments isn’t enough to win the game. As part of the game mechanics, players can earn Power Cards that enable them to engage and challenge each other.
Irrational Game supports 1–5 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 Irrational Game is 20–60 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 Irrational Game for ages 15 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.
