How It Works

Once youโ€™ve opted in at Slot Boss Casino, each spin contributes a portion of your ยฃ0.09 Jackpot bet to the progressive prize pool. When you spin, youโ€™ll see a Jackpot bar displaying the current values for each tier. Your balance reflects your bet and Jackpot contribution, making it all crystal clear.

The Jackpot wheel can trigger on any spin, picking winners at random. The colourful segments determine whether youโ€™ll claim the Mini, Minor, Major, or Mega Jackpot. ๐ŸŒˆ And hereโ€™s the exciting partโ€”every penny of your Jackpot win will be transferred to your account automatically!
