The Courier Who Broke the Bank

The Courier Who Broke the Bank is an achievement/trophy in Fallout: New Vegas which is awarded for successfully banned from all the casinos on the strip, as oppose to the popular misconception of being kicked out of all of the casinos in New Vegas.

Get banned from gambling only in the casinos on the strip - The Tops, Ultra-Luxe, and Gomorrah. The amount needed for each casino to kick you out is, 15000 for Ultra-Luxe, 10000 for The Tops and 9000 for Gomorrah

In order to be kicked out of a casino, you must obtain a high amount of earnings. It has nothing to do with killing people in the casino, stealing, etc. It has been confirmed that different casinos have different limits, and people have said to have been kicked out for different amounts at individual casinos. The Easiest way to get it is start a new player with 10 Luck, and run straight to Vegas, and get up to 2000 caps at the Atomic Wrangler, and then head to the strip. Blackjack is the best game for this. Saving right before you play, and always betting max is a viable option; with 10 Luck, you will win almost every hand. (Note, you will have to wait 60 Seconds after reloading and the max bet is 200 for all games.)

Behind the Scenes
The Courier Who Broke the Bank is a reference to Joseph Jagger (1830 – 1892), a British engineer who was widely known as The Man Who Broke the Bank at Monte Carlo. This name is also attributed to Charles Wells.
