Hosting trivia marathons for couples can be a fun and engaging way to strengthen relationships while enjoying friendly competition. Start by selecting a theme or a mix of categories that appeal to both partners, such as pop culture, history, or personal anecdotes. Prepare a set of questions with varying difficulty levels to keep the game interesting. Divide the couples into teams or have them compete individually, depending on the number of participants. Use a timer for each question to maintain a lively pace, and consider incorporating bonus rounds for extra points. To enhance the experience, provide snacks and drinks, and create a cozy atmosphere. At the end of the marathon, celebrate the winners with a small prize or a fun title. Ultimately, the goal is to foster connection and laughter, making it a memorable evening for everyone involved.
