Know-It-All is a trivia game show you play like a roguelike. Eight rounds, one rival per round, and a prize that climbs all the way to $20,000 - if you have the nerve to keep going.
EVERY MISS SCORES FOR YOUR RIVAL
Pick a subject, choose Easy (1 point) or Hard (2 points), and answer. Get it right and it is your point. Miss, and your rival takes it. First to the target wins the round.
TAKE THE MONEY OR PLAY ON
Between rounds you can end the match and keep everything you have earned, or climb to the next rival for a bigger prize. Lose a round and you leave with nothing. Nothing is left to chance: the only thing that decides a match is what you know.
14 RIVALS WITH REAL WEAKNESSES
Grandma Ruth never misses the easy ones. Kev turns your misses into points. Every rival has a strong subject and a weak one - hit the weak one on Hard and score triple.
40 PERKS THAT BEND THE RULES
Win a round, pick a perk. See rivals two rounds ahead. Survive one miss per match. Double your streak bonuses. Every match builds a different loadout.
YOUR MISSES COME BACK
Every question you get wrong returns as a Rematch a day later, worth double. Your career record, accuracy, best streak and unlocks carry across matches.
26,000+ QUESTIONS, 11 SUBJECTS
General knowledge, history, geography, science, music, movies and TV, sports, arts and literature, food and drink, pop culture, video games. All offline.
DAILY MATCH
One seeded match per day, the same for everyone. Share your result line.
ONE PRICE, NOTHING ELSE
No ads. No in-app purchases. No account. No tracking. Your progress lives on your phone.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Two fixes, both from players who wrote in. Keep them coming.
Fast Pass made passes free in the shop. The perk is meant to let you pass twice a round without spending a token, and that part worked. But it also dropped the shop price of a pass to zero, so you could stack as many as you wanted and the rest of the run stopped costing anything. Fast Pass now does only what it says.
Questions you could not actually answer. A few asked about lyrics, a quote or a list of ingredients and then never showed them, because the text got separated from the question when the bank was built. 34 of those are gone. Most were music questions, which is the worst place for it.
