A test of wit in which characters must solve riddles or answer questions, often with life-or-death stakes.
Riddle contests appear in folklore worldwide as tests of intelligence and worthiness. The most famous example is the Sphinx's riddle to Oedipus ('What walks on four legs in the morning...'), but riddle contests feature prominently in Norse mythology (Odin's wisdom contests), the Book of Judges (Samson's riddle), and African folklore traditions. In fairy tales, riddle contests often serve as the impossible task that only the worthy hero can solve, or as the means by which a clever protagonist outwits a more powerful opponent. The Tolkien dragon Smaug's conversation with Bilbo continues this tradition. Riddle contests encode cultural values about the superiority of wisdom over brute strength.
A character (often an animal or spirit) who exhibits a great degree of intellect or secret knowledge and uses it to play tricks or otherwise disobey normal rules and conventional behavior.
A challenge set by a villain or authority figure that appears unachievable, often resolved through magical assistance or cleverness.
