2. Biggest Losses: When Luck Turned Its Back

Terry Watanabe - $127 Million Down the Divide

What's worse than losing a fortune at a casino? Only if you did it in one year, like businessman Terry Watanabe did . He is one of the most famous " gamblers " in gambling history, having lost $127 million at two Las Vegas casinos, Caesars Palace and the Rio .

Watanabe owned a large company, but instead of enjoying his success, he chose to spend his money on blackjack and baccarat. Casinos, seeing such a big client, gave him private rooms, VIP services, and even free accommodation, if only he would continue to play. But what did Terry get in the end? Only ruin and an empty bank account book.

Archie Karas - The Legend Who Fell

If Terry Watanabe is the poster boy for loss, Archie Karas is the poster boy for how easy it is to fall from grace. Karas is a professional gambler who arrived in Las Vegas in the early 1990s with $50 in his bankroll . Within a few months, he turned that measly sum into $40 million playing poker and craps. But soon after, his luck ran out.

He returned to the casino and lost his entire fortune in a matter of weeks. His losses illustrate how even the most successful gamblers can lose everything in the blink of an eye if they don't know when to stop.

high rollers wagered huge sums of money at baccarat and were the darlings of the casinos, which provided them with every conceivable perk, from private jets to luxury suites. But none of these players ever got their money back, and their defeat was one of the biggest high roller disasters of the era.
