The Casino in Dorias
Some types of specified slot cards can only be obtained by getting a triple seven on a slot machine or by winning poker against the King of the casino. The Risky Dice can be very useful in this city. Gon, Killua and Biscuit get their Fledgling Gambler and Rainbow Diamond cards here.[1]
