Yu-Gi-Oh! Dark Duel Stories

A card battler for Game Boy Color where you duel opponents using the Yu-Gi-Oh! trading card game ruleset. You build decks from available cards, challenge CPU duelists, and earn new cards by winning matches. The game supports link cable connectivity, letting you trade cards with friends or battle their decks head-to-head. Duels play out in a simplified version of the physical card game's mechanics—summoning monsters, casting spells, setting traps. Progress unlocks stronger cards and tougher opponents. It's straightforward: win duels, expand your collection, refine your deck. No story frills, just the core loop of collecting and competing with cards in portable form.
