Product Overview
Hygge Games I Should Have Known That! is a trivia card game based on questions about familiar facts and general knowledge. Instead of rewarding players with points for correct answers, the game subtracts points when a player answers incorrectly. This scoring structure places emphasis on avoiding mistakes while answering questions that may initially appear straightforward.
The documented green-box configuration contains more than 400 questions. Topics cover a broad range of everyday knowledge. Players take turns answering questions while keeping track of deductions from their scores. The game is intended for two or more players ages 14 years and older and typically takes approximately 15 to 45 minutes.
The compact card-based format requires no electronic components or batteries. Article number 21026 and UPC 819940021026 identify the documented original green-box configuration. Other I Should Have Known That! editions use different question formats and standardized identifiers.
