Play the Dolphins Pearl Slot Machine
Novomatic games like Dolphin's Pearl, Sizzling Hot Deluxe and even more so the popular Book Of Ra slot machine have become something of a cult phenomonen in the UK and Eastern European territories like Poland, Hungary and Romania. In fact, all the way across to Novomatic's homeland of Germany and up into Austria, Dolphin's Pearl, Book Of Ra and other Novoline slots like "Lord Of The Ocean" pretty much dominate the more tarditional IGT favorites like the Cleopatra slot machine and Pharaohs Fortune which might surprise some people.
The Dolphin's Pearl slot machine is very similar in gameplay to "Lucky Lady's Charm", "Sea Sirens" and "Egyptian Experience", two other Gaminator-based games from Novomatic in that the free spin feature provides 15 spins at 3x but with pretty frequent retriggers. Also like those two and Book Of Ra, Dolphins Pearl is very, very volatile! You can go a long time without a bonus feature (3 or more scattered oyster shells in view) but when you do, it can retrigger frequently and pay out some very big wins. Not always...but sometimes!
Without the free spins feature, despite the fact that the wild Dolphin symbol doubles all wins, walking away from the game with a profit is very difficult. Not impossible, but rare enough to be notable! Idealy you will get the feature and a couple of retriggers and then you can start to think about profit margins!
If high volatility isn't your thing then I'd avoid Dolphin's Pearl and head off to the the Gladiator slot machine or the brilliant Iron Man 2 slot both of which are entertaining and not feature-dependent like Novoline slots tend to be. Even Aristocrat slot machines like Queen Of The Nile 2 or the twee but fun Where's The Gold slot will probably give you more game-time if you are on a smaller budget.
