Classic Greentube slot titles have been reworked and revamped with a four-level Diamond Mystery™ Jackpot – and hence, the Diamond Mystery™ slot series was born! This outstanding series gives players the chance to win up to 5,000 times their stake with a little luck; values may vary from slot to slot.

Because these slots are popular with our customers, many more titles are being added to the collection every month. This is why we highly recommend you regularly check out our list of this game family to ensure you have the latest and greatest titles in your gaming collection!
