Whether you gamble for a living or just go to enjoy the games and atmosphere, casinos are designed to be exciting places. They usually have flashy decor, upbeat music and plenty of food and drink options. Patrons can try their luck at blackjack, poker and slots with the potential of winning big.

There’s something about gambling that encourages people to cheat, steal and otherwise manipulate their way into a jackpot. That’s why casinos spend a lot of time and money on security. Casino employees watch patrons closely, noticing blatant cheating like palming or marking cards or dice, as well as betting patterns that might indicate collusion between players or managers. Table managers and pit bosses are also on the lookout for suspicious behavior at their tables, including crooked dealing.

Martin Scorsese’s edgy drama Casino was a smash hit, partly because it brought back the glamorous world of organized crime in all its seedy glory. It also boasted a top-notch cast led by Robert De Niro as mob boss Frank Rosenthal and Joe Pesci as his enforcer Sam Rothstein. The movie’s lean three-hour running time and taut pacing kept audiences on the edge of their seats.
