LearnClash: Trivia Quiz Duels

How much do you really know? Prove what you know in quiz duels against real players, from general knowledge to hundreds of other topics. Learn what you don't.

LearnClash is the quiz duel that makes you smarter. Every answer shows the fact behind the question, and the ones you miss come back until you know them.

A REAL OPPONENT, ON YOUR SCHEDULE

Challenge a friend with a link or get matched with another player. Each LearnClash duel has 6 rounds of 3 questions, 45 seconds per question, and both players get the same questions. Duels are turn-based with up to 72 hours per turn, so you play when it suits you. A turn of 6 questions takes about 3 minutes. Both online? Invite your opponent to play live.

EVERY ANSWER EXPLAINED

Right or wrong, each answer ends with the fact behind it. Tap a suggestion or type your own question, and Clash, your AI tutor, explains why.

MISSED QUESTIONS COME BACK

LearnClash tracks every question you answer. Miss one and it comes back about a week later: due questions come first in your Solo Daily Mix and in duels on that topic. Keep getting it right and it moves from Learning to Known to Mastered. That is spaced repetition, built into every duel and Solo session.

GENERAL KNOWLEDGE AND HUNDREDS OF TOPICS

Start with general knowledge, then go deeper into history, science, geography, nature and hundreds of other topics. Can't find yours? Create any topic and LearnClash writes fresh questions for it.

AI RIVALS WHEN YOU WANT TO PLAY NOW

The Rival Ladder has six AI rivals, from Pip to Zenith, each clearly labeled as AI. A rival always answers, no waiting. Beat one to unlock the next. Rival duels never change your rating.
