How it works

Jackpot King is a trio of progressive jackpots connected to the most popular Blueprint Gaming online slots. Play any of these games and you could be randomly awarded one of these 3 progressive jackpots:

Royal Pot: Must drop jackpot

Regal Pot: Must drop jackpot

Jackpot King: Classic progressive with no limit

A progressive jackpot is a cash pot that increases every time someone plays a participating slot. Because Royal and Regal pots are guaranteed to be won before they hit their limit, it pays to keep an eye on the jackpot values and join the action if they get close to their maximums.
