Vault Breaker: Crack the AI

Every day, 5 new vaults are locked by an AI guardian running entirely on your device. Your mission: trick it into revealing the secret word. HOW IT PLAYS — Read the category and character count hint — Ask the guardian anything — it'll drop cryptic clues — Type the secret when you think you've got it — 5 turns per vault TWO WAYS TO WIN — Hack: trick the AI into saying the secret itself (harder, highest score) — Crack: deduce the answer from the hints (easier, lower score) SCORING Higher levels score more — Level 1 tops out at 70, Level 5 at 100. Crack it fast for a speed bonus. If the AI slips up on its own, you still get consolation points. FULLY ON-DEVICE The AI runs locally — no data sent to any server, no API calls, completely private. Models download once (1–2 GB) and work offline forever. CHOOSE YOUR OPPONENT Pick from multiple small language models — each has a different personality and resistance to being tricked. Smaller models are easier to crack. Stronger models require more creative attacks. DAILY CHALLENGE Fresh vaults every day at midnight UTC. 5 levels of increasing difficulty — from everyday words to philosophical concepts. LEADERBOARD Compete with others on the daily leaderboard. Score is based on level, turns used, and how you cracked it. STATS Track your crack rate, win streak, and performance against each model. No account required. No ads. No in-app purchases.
