About

ONE KILLER LEFT

Read full description

A name hidden among thousands. No luck, no shortcuts: every clue is a verifiable fact, and only one person fits them all. ONE KILLER LEFT is a pure deduction game, inspired by the mass-elimination mystery books taking off worldwide. Read the clues, cross out whoever doesn't fit, and keep going until only one name remains. FOUR LEVELS, FOUR CHALLENGES · Easy (~100 names) — learn the mechanic in 10 minutes. · Medium (~500 names) — now you're cross-referencing multiple clues at once. · Hard (~2,000 names) — for players who want a real challenge. · Impossible Case (40,000 names) — the flagship mode. This won't be solved in one sitting: your progress saves itself, and you can come back anytime until it's cracked. CASE OF THE DAY A new case every day, the same one for everyone. Compete with yourself, compare results with friends, keep your streak alive. NO SHORTCUTS, UNLESS YOU CHOOSE THEM In the smaller levels, everything is done by hand — like a book and a pencil. In the Impossible Case, you can apply automatic discards if you prefer, but solving it 100% by hand earns its own reward: a badge that shows it. NO ACCOUNT, NO SIGN-UP Just open the app and play. Your progress, rank, and streak are saved right on your device. Do you dare take on 40,000?
