Dolphin Gold Free Spins

Depending of the number of dolphins that landed in the main game you will get the appropriate number of free spins. The maximum number of free spins will be triggered by a combination of twelve dolphins. For combinations of 6, 7, 8, 9, 10, 11 and 12 pictures of dolphins you will get 3, 6, 9, 12, 15, 18 and 21 free spins respectively.

The number of paylines during a round of free spins will remain the same as it was during the spin that had triggered the free spins in the first place. Your bet per line will also remain the same. These values cannot be changes during a round of free spins. Your line bet will be applied to calculate your payout with the appropriate multipliers. The reward that you earned during the free spins cannot be used in the double-up. A series of free spins may be relaunched if you land six to twelve dolphins again.

Slot Symbols and Multipliers

Pictures that form winning combos will be coming up on the reels. Winning combinations are normally ones with three, four or five identical symbols. Dolphin Gold also provides special combinations of up to 12 pictures.

Combinations of regular pictures are evaluated by applying the appropriate multipliers. The figures are indicated in the paytable and act as multipliers for your line bet. These are the multipliers for the symbols:

  • "9" and "10" - 5, 10 and 25 for three, four and five pictures respectively
  • "J", "Q" and "K" - 5, 10 and 50
  • A coral and a seahorse - 10, 20 and 75
  • Striped fish - 15, 50 and 100
  • A turtle - 25, 60 and 125
  • A stingray - 5, 30, 125 and 500 for two, three, four and five pictures respectively

The Wild symbol depicted as a blue dolphin lands on the second, third, fourth and fifth reels. This symbol does not form any combos of its own, but it can substitute for any picture missing in a combo. These are the extra multipliers that the dolphin provides: rewards for combos with the Joker will be doubled. If a combo has two, three or four Wild symbols, the multipliers will not be added up.

The golden dolphin acts and both the Wild and the Scatter. Regardless of their position on the reels, these symbols will produce a combination that will trigger a series of free spins. You must land 6 to 12 dolphins to qualify for the bonus round of free spins. The Wild symbols will be landing in stacks of one to four. The dolphins may take up four reels entirely (12 fields) and trigger the longest series of free spins. Discover the ocean treasures by playing ocean themed slots for free.
