Play Hyper Dunk - The Playoff Edition (japan) (beta) Online

Hyper Dunk: The Playoff Edition (Japan) (Beta) is an unreleased Sega Genesis basketball game, a prototype that never saw a full commercial launch. It was developed and would have been published by Sega, existing as a curious piece of the platform's extensive sports library from that period. This version represents an unfinished look at what could have been, a snapshot of game development frozen in time.

You control a team of five players in a fast-paced arcade basketball match. The main objective is to outscore the opposing team before the clock runs out. Signature mechanics include performing special dunks, which often trigger brief cutscenes, and executing alley-oops for quick, high-percentage shots. The game moves quickly, demanding fast reflexes for steals and rebounds, and the AI provides a challenging, sometimes unforgiving, opponent. It feels like a rough but energetic take on the sport, where every possession is a frantic scramble to the hoop.
