Online casino JackpotParty.com have gone live with two more online slot games.

The first, The Wizard of Oz Wicked Riches, is a 5-reel mechanical Vegas-style slot boasting free-spin and Winged Money features.

Triggered by a symbol on the third reel, the Winged Monkey feature sees additional winning symbols added to the reels in either the base game or during the free-spin feature.

In the free-spin feature each line win is awarded a random multiplier of up to 10x.

The game also includes a randomly triggered 4-level progressive feature in which higher bet multipliers increase a playerÂ's chance of winning a jackpot.

Players who bet the maximum amount when triggering the feature are guaranteed one of the available jackpots.

The second new release, which is also being launched on Belgian sister site JackpotParty.be, is Spartacus Gladiator of Rome.

The slot utilises the Colossal Reels game engine and offers 100 pay lines in return for 50 credits.

Ohad Narkis, vice president & managing director of online operations for game suppliers and Jackpot Party owners Williams Interactive, said: Â"WeÂ're delighted to be the first online casino in the world with these games.

Â"Jackpot Party continues to provide our players with plenty of one-of-a-kind slots to enjoy when they next pay us a visit!Â"
