Casinos are essentially massive, highly fortified vaults containing millions of dollars in untraceable cash, making them the ultimate, irresistible target for ambitious criminals.

Some thieves used brute force, others used brilliant hacking skills, but all of them attempted to defeat the absolute most heavily guarded fortresses in the world.
The Most Famous Disappearance in Vegas History
Brennan simply walked out the front door of the casino during his lunch break, carrying a completely ordinary backpack filled with $500,000 in cash and chips.

Incredibly, despite being featured on "America's Most Wanted" and hunted by the FBI for decades, Bill Brennan has never been caught or seen again to this day.
Many theorize he was murdered by accomplices shortly after the heist, but no body was ever foundIt is widely considered the absolute most successful solo casino heist in American historyThe simplicity of the crime deeply embarrassed the massive, heavily armed casino security industry The Crown Casino VIP Hack
In 2013, an international syndicate successfully hacked into the casino's highly secure, internal pan-tilt-zoom (PTZ) VIP surveillance camera network.

The casino eventually realized the statistical impossibility of the wins, uncovered the hack, and fired their top VIP manager, though recovering the funds proved incredibly legally complex.
Stealing $1.5 Million in Chips
A man wearing a full-face motorcycle helmet walked briskly to a high-stakes craps table, pulled a handgun, and completely terrified the players and dealers.

The Bellagio simply deactivated the RFID trackers embedded inside those specific $25,000 chips, rendering his massive $1.5 million haul completely worthless plastic.
