You find a number of ocean and marine-themed slots and one that is worth checking out is Dolphin's Pearl Deluxe from Novomatic. This slot is an upgrade from the earlier Dolphin's Pearl slot, which in itself was a very popular slot. Dolphin's Pearl Deluxe has 5 reels and 10 paylines, 1 more than the original version. The minimum bet is 10p while the maximum bet is £100 per spin in this slot.
Dolphin's Pearl Deluxe is, as mentioned earlier a slot themed on the ocean and the life forms in it. The setting for the reels to be positioned in is the deep blue sea, with the reels separated by what looks like water bubbles. The symbols in the game include a lobster, a sting ray, sea fishes, a sea horse, and the numbers 9, 10, J, Q, K and A from a regular deck of playing cards. The dolphin is the wild symbol in the game while the scatter is an oyster with a pearl. The wild symbol replaces all other symbols to form winning combinations except the scatter and adds a 2x multiplier to the winning combination.
The bonus game in Dolphin's Pearl Deluxe is a free spins bonus. It is triggered by landing 3, 4 or 5 scatter symbols across the reels. You get 15 free wins when this happens, and there is a multiplier attached. Another feature that you can use to double your winnings in both the base game and the free spins round is the Gamble feature. Choose the colour of the card that is dealt face-down; choosing the right colour doubles your win and you can continue till you reach the maximum Gamble limit or opt to collect your winnings. Choosing the wrong colour ends the round and you lose whatever you won during that spin.
