You see the girl performing the strip show on the street. But her show is related with street gambling games (such as thimbleriggers, etc...). Her game is based on cards and balls in the glass. 4 balls, marked with cards suits (Diamonds, Hearts, Spades, Clubs) are bouncing on the street. You have a glass, that also have some suit. You must catch in the glass the ball with the same suit, as your glass. To win the set, you must collect all 4 suits-balls. And the beautiful girl will strip for you, when you'll get to the next level.
