Wyoming law forbids gambling unless a nonprofit corporation operates bingo or pull tabs to raise money, and the law requires the game to be traditional paper bingo with players using daubers to mark the numbers on the cards.

Electronic bingo is illegal except at casinos operated by Indian tribes. E-bingo can play like gambling machines in Las Vegas-style casinos, and depending on the games and machines, e-bingo players can finish up to 90 cards a minute.

Some fraternal organizations and nonprofit organizations had e-bingo machines until January 2005 when the Wyoming Supreme Court declared them gambling machines. Those organizations claimed the loss of those machines cost them significant revenues compared to offering only paper bingo.

Now, two major bingo halls remain in Casper: Hilltop Bingo operated under the auspices of the Lions Club of Casper, and Troopers Bingo operated under the auspices of The Troopers Drum and Bugle Corps.

Bingo Blast, registered with the Wyoming Secretary of State in 2006, is operated under the auspices of The Pet Ring Foundation - "helping one animal at a time" - for injured animals.

The Pet Ring Foundation has not raised enough revenues yet to file the annual Internal Revenue Service Form 990.

The Lions Club's Form 990 for its fiscal year 2006 stated it received $3.8 million, with nearly all of that coming from bingo and pull tabs. After bingo payouts and other expenses, the Lions Club's share was $16,655 - $8,675 for its Allen H. Stewart Lions Camp on Casper Mountain, $3,780 to 44 adults for eye exams and glasses, and $4,000 for scholarships.

The Troopers Drum and Bugle Corps' Form 990 for its fiscal year 2006 stated it received $2,375,100 in total revenues, with $2,237,007 of that from bingo and pull tabs. After payouts and other expenses, the Troopers received $114,783.
