Auburn, Wash.-based Muckleshoot Casino will mark its upcoming 21st anniversary by attempting to set a Guinness World Record for largest slot tournament.

On April 30, the casino will attempt to break the record as the first host site for Everi’s 2016 TournEvent of Champions. To claim the designation, more than 3,001 participants must take part. An official Guinness World Records representative will be on-site to validate the achievement.

“Muckleshoot Casino has a history of being an industry leader so attempting the Guinness World Records title for the largest slot tournament is a natural fit,” said Conrad Granito, general manager of Muckleshoot Casino in a prepared statement. “As the first gaming facility in Washington to offer machine play, cashless technology and interactive in-game bonuses, we now aim to be the state’s first casino to secure a world record as certified by an official Guinness World Records judge.”

More than $100,000 in cash and prizes will be awarded to participants. The top finisher at the event will receive $21,000 in cash and a four-night trip to Las Vegas to compete for a chance to win $1 million in Everi’s national TournEvent of Champions championship event on September 28, 2016.

“While our TournEvent of Champions slot tournaments always bring fun and excitement to casinos nationwide, Muckleshoot Casino has taken its event to an entirely new level by attempting to break the record for world’s largest slot tournament,” added Linda Trinh, vice president, marketing and promotions for Everi. “We’re thrilled to partner with such a distinguished property like Muckleshoot Casino and look forward to making this TournEvent of Champions event one for the record books.”

The official Guinness World Records attempt at the largest slot tournament will mark the culmination of Muckleshoot Casino’s landmark 21st anniversary celebration. From its humble start in a tent in 1995, Muckleshoot Casino now proudly serves as the largest gaming establishment in the Pacific Northwest.
