THE BULL PEN CASINO
If gambling is legal in the state, why shouldn't it be legal within the walls of the state prison in Carson City? As unlikely as this sounds, gambling was to be a recreational activity made available to prison inmates. In 1932, the Bull Pen Casino opened in the Carson City prison and was oper-ated by inmates, who were allowed to keep their profits. Naturally, the casino customers were all inmates as well.
In order to operate a game, the game boss (inmate) had to satisfy a prison administrative board that he could afford to bankroll the game.
After obtaining approval from the board, the only other requirement was that the game boss contribute a fixed amount of the proceeds to an Inmate Welfare Fund. With the. exception of this limited form of taxation, the game boss was allowed to run his game and keep the profits. The Bull Pen Casino provided the game boss with one of the few benefits of receiv-ing a long prison sentence.

Перевести просто "тюремное казино"? Как-то уж больно банально. Хотя другого варианта придумать пока не могу.
