What can be illegal about a casino other than missing a gambling license? I don't know.
Well the first thing that comes in my mind are gambling games in illegal casinos! Except traditional games we play (poker and many card games, slots, roulette, all sort of dice games...) maybe they organize betting on some fights (humans or animals...)...
I got more interested in this topic, so I did a little research... I found some interesting stuff!
"Other than horse racing and the lottery, all forms of gambling are illegal under the Thailand Gambling Act of 1935. The penalties range from 500 to 5000 baht (about $15 to $150). ... There are over 50,000 arrests a year for gambling in Thailand."
"National Lottery is the only form of legal gambling that most people in Thailand have access to. This began in 1974. Today drawings are held on first and sixteenth day of every month"
So as you see all gambling games are illegal, so this illegal casinos can't get any licenses... It's not what I thought at first!
