Play Yu-Gi-Oh! Duel Monsters (Japan) Online

Konami released Yu-Gi-Oh! Duel Monsters for the Game Boy in 1998, bringing the early card game to handhelds during a time when portable RPGs and strategy titles were gaining traction. It was one of the first digital adaptations of the franchise, offering a simplified version of the tabletop experience on a system known for its monochrome displays and chiptune audio.

You control a duelist traveling between locations, challenging opponents to card battles with the goal of defeating all rivals. The game involves building a deck from a limited pool of cards, engaging in turn-based duels where you summon monsters, set traps, and cast spells. Exploration is screen by screen, with some light NPC interaction, and the pacing is deliberate, though the AI can be predictable once you learn its patterns. It feels like carrying a condensed version of the card game in your pocket, with just enough strategy to keep you engaged between real world matches.
