Ironically enough i got addicted myself, playing those slots, trying to take all the money from Tony. Gotta say, it was pretty tough, got close once, but ran out of "Fun" meter. After several attempts i've realized that i'm becoming Tony, heh.
Pretty nice concept and the mechanics keep you engaged, even though some could say it's partly because of the gambling mechanic. But i think it's not that simple, since the resource here is not the money, but attention, so you gotta be more strategic than just rely on random chances.
Good job!
