London based social casino game developer, Plumbee, has added a new level of entertainment and opportunity to some of its most popular games on Mirrorball Slots: Kingdom of Riches.

The newly-launched progressive jackpot feature is available to players on both Android and iOS and has initially been integrated into slots like Goldilocks, Sevens High, Big Bad Wolf, Leprechaun’s Loot, Royal Frog and Crystal Queen. Over time, the progressive jackpot will be added to more games.

Explaining how the game works, a company spokesman revealed that the jackpot counter will be displayed in all games with a currently active jackpot. The jackpot is divided into 4 different tiers: Mini, Major, Grand, and Super.

Each tier has a different prize pool with the prizes increasing significantly as the player moves up in tiers to the ultimate grand prize in the Super tier.

Each tier has a range of bet sizes assigned to it. When players change their bet size within the game, the jackpot widget will show them which tier they are eligible for. Players may choose to play on any bet size within the tier to win; however, higher bets have a better chance of winning the jackpot.

When a player hits the jackpot winning spin, the game will load the jackpot feature and with it an opportunity for a mega win.

“With Progressive Jackpots, we have introduced a classic slot machine mechanic into our fantasy themed world of Mirrorball Slots” said Plumbee’s product manager, Royyuru Avinash. “Progressive Jackpot reflects our belief that blending proven casino mechanics with technology and game play innovations, provides the novelty and superior experience that players are looking for.”
