liers Williams Interactive have launched two new online slots via their Jackpot Party online casino brand.

Wizard of Oz Wicked Riches is a 5-reel mechanical Vegas-style slot boasting a randomly triggered four-level progressive feature in which higher bet multipliers increase a player’s chance of winning a jackpot.

Williams Interactive vice president & managing director of online operations Ohad Narkis said: “We’re delighted to be the first online casino in the world with these games.”

“Jackpot Party continues to provide our players with plenty of one-of-a-kind slots to enjoy when they next pay us a visit.”
