Retailers such as Target and Walmart sell trivia games and books appropriate for senior citizens online and in store. Trivia games and books are also available through Amazon.com, and free online games can be found on the Suddenly Senior website.
Trivia games can improve cognitive function amongst senior citizens. Trivia games such as "Trivial Pursuit," "American Trivia" and "Bible Trivia" offer seniors mental stimulation in areas of the brain that may not receive much use. Trivia books written for senior audiences such as "Nostalgic Trivia for Seniors" and "Trivia Challenge for Seniors" cover era-specific topics, including films, sports and history.
