About The Master Negotiator
The Master Negotiator is a haggling game with a retro CRT look. You buy low, sell high, and talk your way through haggling sessions with AI-driven characters, typing your offers or speaking them in voice mode, and every deal turns on how persuasive you are.
The creator wanted to turn a real-life skill into a game, so that shy, introverted people can practice negotiating and avoid getting scammed. The creator used Claude Code, and the game came 382nd of 945 entries in Vibe Jam 2026.
The characters remember how earlier deals went, so burning someone once can come back at you later. A multiplayer mode adds PvP betrayal contracts, where other players can double-cross you, and all of it works on a phone too.
