Big Winner, Ultra-Luxe

 is an unmarked quest in Fallout: New Vegas.

Quick walkthrough
You need to play the games that the casino has to offer (Blackjack and Roulette) until you are banned from gambling in the casino. The Ultra-Luxe does not have any Slots machines because they think it is very noisy. You can be banned by winning too many games and getting too much money from the casino. During this process, you will be receiving three different prizes from the casino. Each prize will be given after you win a certain amount of money while gambling. These prizes are usually given by the Table Manager of the casino.

Detailed walkthrough
As you win the games the casino has to offer, you will be receiving the rewards below after reaching its money target:


 * 3,900+ chips = Atomic cocktail
 * 7,500+ chips = Brahmin wellington
 * 11,250+ chips = Bon Vivant suite key

After earning 15,000+ chips, you will be banned from playing games in the Ultra-Luxe. You can still use its other functions, like the bar, but you cannot gamble on its tables anymore. This ban is permanent.
