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.

The Legend of Bill Brennan

One of the most famous unsolved casino heists occurred in 1992 at the legendary Stardust Casino.

During his lunch break, he casually strolled out of the casino with $500,000 in cash and chips.

• Stolen amount was roughly $500,000
• No violence or weapons were used
• The FBI never solved the cold case

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

The hacker used the surveillance cameras to look at the dealer's cards during VIP games.

The casino eventually discovered the breach and managed to recover most of the stolen funds.

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