During the 90's there were some street hoodlums from my area and few of them were quite feared, even by the local organized crime individuals and also the cops. So they would enter some casino, and the security guys were usually shaking in their boots and werent able to lift a finger....and so these guys placed some money on the roulette and then 3 or 4 guys would've lifted the whole table and when the ball shoots out, it didnt go round or in a circle but instead, it would fly in a straight line and hit the wooden or glass wall of the roulette and quickly land on some number, at least 10 seconds BEFORE the electronic voice said "no more bets". And then obviously they would hit the button of that same number more than a dozen of times and walk out with their cash lol.

I dont know much about gambling (and I dont want to) but I heard stories that Blackjack is allegedly the only game in which you have chances in winning and finding out the combinations. Not online or on some machine, but on a table with cards.
