The cards are always stacked in favor of the casino. Casinos exist for one reason, and one reason alone: to take your money. They do it legally, even if it's under cloudy circumstances.
Consider the case of an Alabama man who put $5 into an electronic bingo machine at the Wind Creek Casino in Montgomery, Alabama. The casino is on tribal land operated by the Poarch Band of Creek Indians. To the gambler's amazement, "several noises, lights, and sirens were activated" when the machine announced that Jerry Rape had hit The Big One. The bingo machine indicated a jackpot of $459,000, then $918,000, and finally settled on a "payout multiplier" of $1,377,000, according to the gambler's lawsuit.
The casino took Rape's payout ticket and made him wait for about 24 hours before saying no dice. He wasn't getting the monster payout. The machine, he was told by the tribe's casino, had "malfunctioned." (PDF)
It gets worse
The gambler sued the casino in the tribal court of the Poarch Band of Creek Indians. But the suit was dismissed. The court declared that sovereign immunity prevailed—that the tribe was an independent nation and immune from being sued.
"They said they were immune to any kind of fraud that I made in the complaint," the gambler's attorney, Matt Abbott, told Ars in a telephone interview. "They said rules don't apply to them, [and] 'have a nice day.'"
Unable to lodge a claim in tribal court, Rape rolled the dice with Alabama's state courts and sued the tribe there. On Friday, seven years after Rape thought he had hit the jackpot, the Alabama Supreme Court ruled that Rape could not sue the tribe in state court—the proper venue was tribal court. That's because the Poarch Band of Creek Indians is a nation of itself, and that's where disputes occurring on that land should be litigated, the court found.
