Pub Quiz
Mixed categories, 20-question rounds, points tally. Pub Quiz is the closest browser version of the Tuesday-night bar format. Solo or pass-and-play.
History Quiz
From ancient Egypt to 21st-century politics. History Quiz rotates 800+ questions. Strongest categories: Roman Empire, World Wars, US civil rights era.
Science Quiz
Chemistry, physics, biology, and astronomy. Science Quiz tests named laws, element symbols, and cause-and-effect chains. Average score on the hardest mode: 54%.
Food Quiz
Cuisine origins, dish identification, ingredient chemistry. Food Quiz tends to humble even self-proclaimed foodies — most people don't realize tempura originated with Portuguese sailors.
Animal Quiz & Dinosaur Quiz
Animal Quiz identifies species and habitats. Dinosaur Quiz covers paleontology — strongest on Triassic-to-Cretaceous transitions.
Mythology Quiz & Anatomy Quiz
Mythology Quiz spans Greek, Norse, Egyptian, and East Asian mythologies. Anatomy Quiz is tougher than it looks — 30% of trivia nights stump on anatomy questions, per UK quiz federation data.
Space Quiz
Planets, moons, missions, cosmic phenomena. Space Quiz is the one where knowing the order of planet moons wins.
Movie Trivia
Directors, quotes, plots, box office. Movie Trivia is the cinephile filter. Tends to skew post-1970s — don't expect deep silent-era questions.
What makes a good quiz game
Three things separate solid quizzes from filler:
- Question diversity: at least 500 unique questions to avoid repetition
- Difficulty tiers: easy → hard within the same category
- Fast feedback: answer explanations, not just right/wrong
Players retain 40% more info from quizzes that show brief explanations vs those that just show the correct answer. This is a well-replicated finding in learning science.
Why quizzes stick
Retrieval practice. When you try to recall an answer (even if you get it wrong), you strengthen the memory pathway. This is called the testing effect, and it's why quiz apps are better study tools than re-reading notes.
