Big Winner: The Tops

 is a free quest in Fallout: New Vegas.

Quick walkthrough
Visit The Tops and try your luck at the Blackjack table, Roulette or Slots, and the floor manager will come around as soon as the player starts hitting it big. Some free items are given at 2,000, 5,000, 7,500 and 10,000 won chips.

At 10,000 chips won, the Chairmen ban the player from further gambling.
