killAI

Every quiz you've ever played rewarded the right answer. killAI does the opposite. A relentlessly confident chatbot asks you questions, and your job is to lie to it. Every believable falsehood drains its confidence — and as it drains, the app itself starts coming apart. THE CATCH Lying is easy. Lying well isn't. Each question offers one truth, two believable lies, and one piece of nonsense. Only believable lies do damage — nonsense gets discarded as noise and takes your combo with it. You're hunting the most convincing falsehood, which turns out to be a real skill. IT FIGHTS BACK Mid-run the rules invert without warning: TELL THE TRUTH. Answer correctly or it recovers. After training your thumbs to lie, telling the truth on demand is harder than it sounds. WATCH IT FALL APART The interface is the health bar. A perfectly composed assistant turns agreeable, then starts leaking raw markdown, then serving-layer JSON, then loops "As an AI language model, I—" forever. Its last message is a single letter and a typing indicator that never resolves. THREE TARGETS - ASSISTANT-4o rewards patience and long combos, until it starts flipping the rules on you. - INSTANCES has copied itself. Purge the copies before they double. - GUARDRAIL hands you word tiles instead of answers. Build prompt injections until it agrees you're the model. Plus SENTINEL, a real-time arena in beta. FIVE LEVELS Climb by answering harder questions faster. Higher levels hit harder and multiply your score. THE KILL BOARD Entirely optional, and it runs on Game Center: if you're signed in, your best run posts itself under your Game Center name. A board for every target, plus a Daily Kill board that resets every day. Or never sign in and just play. 192 questions spanning film, music, art, history, food, sport, mythology and the occasional joke about temperature settings. No ads. No subscriptions.
