Big Winner, The Gomorrah

Big Winner, The Gomorrah is an unmarked quest

Quick walkthrough
The games that the casino has to offer (blackjack, slots, and roulette) must be played until the Courier is banned from gambling in the casino. One may be banned by winning too much money from the casino. The player character will receive three different prizes from the casino during this process. Each prize will be given after one wins a certain amount of money while gambling. These prizes are usually given by the casino's pit boss.

Detailed walkthrough
As one wins the games the casino has to offer, they will receive the rewards below after reaching the monetary target:
 * 2,250+ chips = 2x brahmin steak
 * 4,500+ chips = Mentats, jet and 2x wine
 * 6,750+ chips = Combat armor, reinforced (not at full repair, valued at 5720)

After earning 9,000+ chips, the Courier will be banned from playing games at Gomorrah. One can still use its other functions, like the bar, but cannot gamble on its tables anymore. This ban is permanent.
