Big Winner, Ultra-Luxe

 is an unmarked quest in Fallout: New Vegas.

Quick walkthrough
Like with the other Bigger Winner quests, the player can take a seat behind the Blackjack- or Roulette table of the Ultra-Luxe, and a floor manager of the White Glove Society could come by several times. If Luck holds on, he will do this four times, at winnings of 3,750, 7,500, 11,250 and 15,000 chips.

At 11,250 chips won, the player is given the key to the Bon Vivant Suite. However, at the 15,000 mark a ban follows.
