The immense amount of cash flowing through casinos naturally attracts the world's most ambitious criminals.

While modern security makes physical theft almost impossible, history is full of spectacular heists.

Bill Brennan and the Stardust Robbery

Unlike elaborate armed robberies, this heist involved a single man and a backpack.

He was never seen or heard from again, becoming an enduring legend in Las Vegas lore.

• Occurred at the Stardust Casino in 1992
• The thief was a trusted employee
• He disappeared without a single trace

Phil Ivey and the Baccarat Edge

This sophisticated method involved identifying tiny manufacturing defects on the backs of playing cards.

Lengthy legal battles ensued, ultimately resulting in judges ruling that edge sorting constituted cheating.

The Ocean's Eleven Style Heist

A high-roller colluded with a rogue security expert who hacked into the casino's camera network.

Information was then secretly relayed to the player at the table via a wireless earpiece.

These incredible stories remind us that casinos are engaged in a constant arms race with clever criminals.
