Jackpot Slots

You can play on some of our top slots and the Jackpot will just keep rising until a player lands the correct symbols to trigger the jackpot. If you prefer our other online casino offerings you can browse through our casino games for a range of different slots with many different features.

In order to win the Jackpot King Progressive Jackpot, you'll need to enter the Jackpot King Bonus Round. Find 5 Golden Crowns on the reels after any spin, and the bonus round will begin. You'll then be shown the Super Reels, where you'll have to find even more Golden Crowns. The more Golden Crowns you find, the higher up the Cash Trail you will go, taking you closer to the Wheel King Bonus. Along the way, you'll also find pieces of the King's Treasure, which will give you cash prizes, or even Free Spins. When you reach the top of the Cash Trail, you'll begin the Wheel King Bonus. Here, you will spin the Wheel to win up to a 1000x multiplier, or who knows, you might even win the jackpot itself!

But how does the Jackpot King increase? 0.13% of each stake is added to a reserve pot. When the Jackpot King is won, it will reset to the reserve pot value. The Jackpot begins with a seed fund initially. Then, 0.86% of each stake placed is then added to the progressive pot. Then remaining 0.13% is added to the reserve pot.
