Play Pro Yakyuu Satsujin Jiken! (Japan) Online

Pro Yakyuu Satsujin Jiken! came out on the Nintendo Entertainment System in 1986, developed and published by Konami. It was part of that wave of early NES titles that experimented with mixing genres, a detective story wrapped in a baseball game's uniform.

You control a detective investigating a murder within the world of professional baseball. The main objective is to interview a cast of quirky characters, each who speaks entirely in baseball terminology, and gather clues to find the culprit. Signature mechanics include navigating the environment screen by screen to find witnesses and engaging in sudden, random batting practice minigames that test your timing. The pacing is deliberate, and the difficulty comes from interpreting the odd jargon and knowing where to look next. It feels like solving a bizarre, sports-themed puzzle where every conversation is a curveball.
