If you’ve ever played slots at a live casino, the chances are that you’ll have stumbled across Dolphin’s Pearl Deluxe. Games developer Novomatic has created this Deluxe online version of the fishy brick and mortar favourite. It’s a highly volatile 5 reel, 10 payline affair that comes with free spins and multipliers. Take a dip in the ocean from between 10p and £100 per spin.

As in most of its slots, Novomatic has kept the visuals in Dolphin’s Pearl Deluxe pretty simple – the setting is a dark blue, underwater backdrop with the reels filled with an assortment of brightly coloured aquatic creatures including starfish, lobster and skate. There’s nothing flashy on show but everything is nice and clear. There’s not much of a soundtrack to speak of, just the hypnotic thud as the reels fall into place and the occasional fanfare for a winning spin. Don’t expect your senses to be overloaded.

It’s a similar story with the gameplay. The first thing to look out for is the dolphin which is the game’s wild. It substitutes for all other symbols apart from the scatter. When the dolphin appears in a winning payline, that combination will be subject to a 2x multiplier and the payout doubled. The dolphin is the game’s biggest payer, offering massive payouts of 900 times your line bet if you find 5 in a payline.

Find 3 or more of the pearl scatter symbols and you’ll be awarded 15 free spins. All winning spins during the bonus round will benefit from a 3x multiplier with all winning paylines trebled. It’s possible to retrigger more free spins during the bonus round if the pearl scatters appear again. There’s no limit to the number of times this can happen.

The setting for Dolphin’s Pearl Deluxe may look tranquil and calm but the fast-paced action is in fact extremely volatile. This is a high variance slot requiring plenty of patience and a deep bankroll. Getting the free spins and then retriggering them is the key to winning big. The free spins don’t come around very often but when they do the wins can be lucrative.

Dolphin’s Pearl Deluxe is not for the faint hearted but if you’re feeling brave and have the bankroll to match, the rewards can make that persistence well worthwhile. I prefer other Novomatic slots like Lord of the Ocean personally but if you like aquatic themes, Nemo’s Voyage by WMS is very good (and different).
