Jackpot King Prize Lines Bonus Features
Game Symbols
It’s not a classic machine where each symbol has its value. Here, you will have only several symbols that determine what you can get.
- Red diamonds cover the reels at the beginning of the round. They don’t have value and the goal of players is to replace them with crowns.
- Crowns that appear on the reels turn golden and lock-in positions. The more of them you get, the more winning lines you can form.
- Golden coins launch the Choose an Item bonus option and turn into a locked crown after this.
Bonus Rounds & Free Spins
Players will appreciate the bonus features the Blueprint team has prepared: as well as the gameplay, the options are unusual and profitable.
Choose an Item is a feature that is launched by a golden coin on the reels. You can pick 1 of 4 things: a golden cup, a ring, an orb, or a scepter. They can randomly award extra spins within this round (1–3), additional crown symbols (1–3), or the triggering of the Wheel King.
The Wheel King feature is triggered when the crowns cover the entire field or when an object you pick (Choose an Item) launches it. In this game, you have 1 spin of the wheel that determines a multiplier for your current winning. This amount can come up to 1,000x bet.
Spin-Crease Chance is an option that is offered when your spins are spent. You can collect the current winning or buy additional spins. If you continue this level, the crowns on the field are left so that you can cover the whole field faster. The price of these spins varies: the more crowns you have already got, the more expensive this feature is.
Jackpot
The Wheel King feature provides not only multipliers. Besides, there are 3 types of jackpot gamblers can count on: Royal, Regal, and Jackpot King.
