Banked games were those games requiring someone to put up money to back the game.
  Such games included: Faro, Keno, GrandHazard, Red and Black, Vingt-Et-Un, Chuck-A-Luck
  and Roulette.  This was either done by the saloon  owner or a professional gambler that the
  saloon owner leased floor space to. Leasing floor space for gambling purposes was a very
  common business arrangement which benefited both the business owner and the professional
  gambler.

                                                                                                  
  Many of the gamblers listed on this site at one time or another leased floor space in various
  saloons throughout the southwest. Doing so allowed them to quickly and easily pick up and move
  on as the railheads moved west or new gold and silver strikes were made.
