Power-Up Duels
Bring 50/50, Shield, and Double Down into a five-question duel. A wrong or missed answer costs 5 points before power-up effects.
Coin tables
Start at free Practice Grounds or stake 100–10,000 coins at a table you have unlocked. The winner receives both stakes.
Friend challenges
Find players by username and invite them to your chosen topic, duel style, and table. Rematch to keep the rivalry going.
Bot battles
When no live rival is available, face a bot with your chosen rules and table. Questions follow your skill in the topic.
Survival
Take on fifteen questions with three lives, moving from easier to harder rounds. A wrong or missed answer costs a life.
Your Power-Up toolkit
One question can change the match.
Buy power-ups with in-game coins. Use each type once per match, before you answer, to affect your current question.
50/50
Remove two wrong answers and focus on the remaining pair. 50/50 can also be used in sudden death.
Shield
Turn a wrong or missed answer into zero points instead of a penalty. Shield also protects a question played with Double Down.
Double Down
Double the points you win or lose on the current question. A correct answer earns 14–20; an unshielded wrong answer loses 10.
Shield and Double Down are available in regular rounds. Sudden death is decided by who answers correctly first.
