Play Knock-Out Kings Online

Electronic Arts released Knock-Out Kings for the Game Boy Color in 1999, a time when portable boxing games were rare and often simple. It stood out among other sports titles on the system for trying to capture the feel of a real fight in your hands.

You control a boxer, moving left and right, throwing jabs and hooks while trying to avoid incoming punches. The main goal is to climb the ranks in career mode or knock out a friend in versus. Key mechanics include timing your dodges to avoid damage, building up a super punch meter by landing hits, and managing your stamina between rounds. The pacing is deliberate; you can't just button mash. Matches require patience and reading your opponent. It feels satisfying when you finally land that clean counter and see them hit the canvas.
