Liar's Duel: Logic vs AI

The AI's answers may be lies. And yours can be too. Ask yes/no questions, uncover your opponent's secret arrangement, and name it first to win. A quick one-on-one deduction duel where bluffing is part of the rules. START WITH PEACE OF MIND - Free to start. No subscription - No third-party ads (the free version may show our other apps) - Your records stay on your device and are never uploaded HOW IT WORKS - You and the AI each hold a secret: who holds which item - Take turns picking a yes/no question from the menu - Each side may lie a set number of times. The limit is public; whether you used it is not - When the AI asks you, you decide: answer honestly, or lie - When you know, declare the whole arrangement. Hit and you win. Miss and you lose on the spot FEATURES - Six AI ranks: Grade School, Middle School, High School, College, Doctorate and Prodigy - Each rank differs in question sharpness, memory, how it uses lies, and when it dares to gamble - Rank ladder: beat a rank to challenge the next.
