Hugo, the big casino guard, can be encountered in the Casino in the lower levels of the Caverns of Chaos. He is not hostile unless attacked or unless the casino shop is robbed. However, if the player wins any money at slot machines, he will block the down stairs and not allow passage unless that much money and more is spent at the Great Gift Shoppe. (Note: as of release 60, Hugo only steps next to the stairs onto it, thus allowing the PC to pass despite his chat indicating the contrary. This is likely bugged behavior - Hugo correctly blocked the stairs in v1.1.1.)
