Hi bb1webs,
Within the Vegas VIP Lounge group of casinos, the “Break Da Bank” reel slot game is only available at Colosseum Casino. When launching a new casino, I guess MGS operators can decide which games better suit their needs and add them to their new property. I suppose (and this is my own personal opinion) Break Da Bank was not very popular amongst existing Colosseum players at the time, and the management decided not to include it in later casinos.
So all is not lost, you can still enjoy Break Da Bank at Colosseum 
Hope that helps…
