Mystery Jackpot Spinner is a slot game made to order for the Betsson Group. This means, the game is available on their brands only. Casino Euro, Betsson, Betsafe for the UK and e.g. Norgesautomaten or Sverigeautomaten for the other markets. The design and sounds are simple and rather subtle but on the other hand we are awarding Mystery Jackpot Spinner with a high fun factor. https://www.powerballsite.com/
