Egypt has a variety of Casinos, mainly in Cairo and in Sharm el Sheikh and probably in other Touristic Cities.
Everyone from all over the world can go into these casino's and spend as much time and money as they like EXCEPT for Egyptians themselves.
Regardless of whether they are muslims or christians they cannot even enter a casino.
Arabs can enter, they are usually the people who go there - rich arabian men whose wallets feel too heavy for their pockets.
It's obviously not about religion - as gambling is not acceptable in Islam.
I wish i could find an explanation for that.
