Big Winner, Ultra-Luxe

Big Winner, Ultra-Luxe is an unmarked quest in Fallout: New Vegas.

Quick walkthrough
Play the games that the casino has to offer (Blackjack and Roulette) until getting banned from gambling in the casino.

The Ultra-Luxe does not have any slot machines, as they believe they are too noisy. As the player wins, three different prizes will be received from the casino. Each prize will be given after winning a certain amount of chips while gambling. These prizes are usually given by the table manager of the casino.

After winning a large amount of chips, the player will be permanently banned from gambling at the casino.

Detailed walkthrough
NOTE - This is the only casino to not offer slot machines, only blackjack and roulette. As the Courier wins the games that the casino has to offer, they will receive the below rewards after reaching the target chip amount:
 * 3,750+ chips: atomic cocktail
 * 7,500+ chips: brahmin Wellington
 * 11,250+ chips: Bon Vivant suite key

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