A collectible card game based on the Yu-Gi-Oh! television series, this game lets you construct your deck, duel rivals, gain experience, and ultimately face off with the four Rulers of Ancient Egypt, keepers of the fabled Millennium Items. Strategy is the key as you unleash attacks like Fusion and Sacrifice to summon ever more powerful monsters. Defeat opponents by skillfully using monster and magic cards to your advantage to become the King of Games. Players can compete against either the game's artificial intelligence or another Duel Monsters player via the Game Boy link cable. Selecting from a deck of hundreds of unique battle cards with thousands of possible combinations, players must attack, defend, and combine monsters and set traps in order to drain their opponents' life points and win the game. Players must carefully build up their 40-card deck, selecting from eight different types of cards (earth, wind, water, fire, dark, light, magic, and trap) in order to compete on the Duel Field.
