Winstar Slot Bonus Features


Winstar offers a Mystery symbol that looks like a gold star. It will spin to reveal a new symbol that can be used to complete a winning combination. Mystery symbols appear randomly throughout the game.


This game uses the Jackpot King feature found in other Blueprint games. It is a multi-stage game that gives you the opportunity to play for the progressive jackpot if you make it all the way to the final stage. slots that are plugged into the jackpot king determine their prizes a little differently.

I bet you’re wondering how the Jackpot King gets so big? Well, 0.13% of each stake is added to a reserve pot. When the Jackpot King is dropped it will reset using the reserve pot. The Jackpot begins with a seed fund , which means the Jackpot ends up being funded by the initial seed with an added 0.86% of each stake. Then the final drips of that is the equivalent to 0.13% which is given to the reserve pot.
