World War II

How a duel works

• 7 questions, 10 seconds each, against a live player when one is free, otherwise a real player's earlier run or a bot. Opponents are always labeled.
• A correct answer is worth 10 points, plus up to 10 more the faster you answer. The last question counts double: 160 points at most.
• Every finished duel earns XP for your topic and overall level.
