Big Winner, Ultra-Luxe

 is a quest in Fallout: New Vegas.

Quick walkthrough
Like with the other Bigger Winner quests, the player can take a seat behind the blackjack table or roulette table of the Ultra-Luxe, and a floor manager of the White Glove Society will come around to congratulate him on the winnings. This time, if Luck holds on, he will do this four times, at 3750, 7500, 11250 and 15000 chips.

At 3750 chips won, the player is given the key to the Bon Vivant Suite. However, at the 15000 mark a ban follows.
