As in "Magic: The Gathering", "Duel Masters" players summon creatures and cast spells using mana. Key differences include the fact that all creatures and spells can act as mana producers, creatures cannot block attacking creatures without having the “blocker” ability, and that creatures only have one “power” statistic. Furthermore, duelists have shields in the form of cards that go to their hand when “broken” as opposed to "Magic"s “life points”. Owing to the popularity of "Duel Masters", four video games (three released for the Game Boy Advance and the other for the PS2) based around the game have been produced, titled "Duel Masters: Kaijudo Showdown", "Duel Masters: Sempai Legends", "Duel Masters: Shadow of the Code" for the GBA and "Duel Masters: Cobalt" for the PS2.
