The first ever World Series of Slots tournament, held in April at the Golden Nugget Hotel and Casino in Las Vegas, US, welcomed 280 competitors battling head-to-head through eight rounds, and gave away a total of $262,000 in prize money.

Cash prizes were awarded for advancing through each round. Participants won $500 for advancing to round two, then an additional $150 for each round thereafter.

San Diego resident Michele Leone walked away with the $100,000 grand prize and championship bracelet for her slot victory, followed by Vera Panjanon-Wolf in second place with $15,000, Arsenio Mata in third place winning $10,000 and Lien Phan rounding out the top four with $8,000 in prize money.

"A World Series of Slots has never been done before and players from all over loved the head-to-head challenge," said Tilman Fertitta, chief executive officer of the Golden Nugget. "This event was a huge success that we’re sure to repeat in the future."
