Battle City Rules

Battle City Rules are enforced by Seto Kaiba during the second season of Yu-Gi-Oh! (Battle City Tournament). They are as follows:

• Players begin at 4000 Life points.
• Level 4 or below monsters can be summoned once per turn during a normal summon (e.g. Kuriboh, Level 1)
• Level 5-6 monsters need one Tribute in order to normal summon (e.g. Summoned Skull, Level 6).
• Level 7-8 monsters require two Tributes to normal summon (e.g. Dark Magician, Level 7].
• Monsters with Level 9 or more require three Tributes to normal summon (e.g. Egyptian God Cards).
• Fusion Monsters must wait one turn after they are summoned before they can attack.
• If your opponent has no monsters in play, you are free to attack his or her Life Points directly, reducing their total by the monster's ATK value.

And the most important rule:

• For each Battle City duel, each player must ante their rarest card and a minimum of one Locator Chip Cards in their possession. The winner of the duel obtains their opponent's card and chip cards wagered.
