A port of the land-based casino game of the same name – a common tactic for Aristocrat, who entered the real money gaming space decades ago producing offline pokies – Dolphin Treasure is a fun and attractive naval themed slot.

It's worth a look for players as the jackpot and bonus rounds can be more lucrative than some of the other Aristocrat slots you'll find on the web.

With reel icons featuring seahorses, starfish, turtles, treasure chests and golden sunsets, there are no prizes for guessing where this game is set; the action all takes place under the sea.

You could be forgiven for missing the dolphins for which the game is named entirely, as they only show up when the wild sunset icon animates during a win. The game is pretty enough, although it's no longer the cutting edge beauty it once was, and it certainly gets the job done.

The in-game music, which doesn't always seem to kick in at every online casino, is a rousing steel drum number reminiscent of the undersea levels of classic games like Donkey Kong, which further helps to establish a mood. It's a bit frenetic at times, like during the bonus round, but still very enjoyable.

You'll also come to love the signature dolphin noises that come with wild wins...

The gameplay of Dolphin Treasure – with 5 reels, 20 paylines and wild sunsets that also double any wins where substituting for another symbol – is nothing out of the ordinary but it does represent why Aristocrat's titles are so well regarded.

Simple to get to grips with, but thoroughly compelling to play, Dolphin Treasure has all of the necessary ingredients for an exciting session playing pokies. Chief among these is its bonus round, which features 15 free games with a 3x multiplier.

Although this is now just about par for the course in modern online pokies, it's a slightly different tack to the more volatile take that some other Aristocrat slots take. For example, Choy Sun Doa and 5 Dragons offer a maximum possible multiplier of 30x but as few as 5 free spins in their bonus rounds.

Dolphin Treasure may not be as popular as titles like 5 Dragons, which accounts for a huge percentage of the offline gaming machines operating in Australia, but it's still a firm favourite with many Aussie players.

This may because it's less volatile than those slots, so players are perhaps less likely to snare its 9,000 coin jackpot, but that might actually suit players who prefer to land smaller, more consistent wins.

That said, it's not always so easy to land wins in Dolphin Treasure! Twenty paylines sounds like a lot, but you can still find yourself thinking "how was THAT not a win?!" after some spins.

Minor niggles aside, Dolphin Treasure makes for a nice session playing pokies online. There's a fine line between betting big enough to make for a hefty jackpot without burning through your bankroll very quickly, so we recommend giving it a try in free play mode first.

Dolphin Treasure is a pretty simple game, with 20 paylines and some wild symbols thrown into the mix. The theme itself looks nice enough and the bonus round, 15 free spins with a 3x multiplier, is not bad at all. Still, it's difficult to get too excited about Dolphin Treasure and a maximum jackpot of less than 10,000 coins is not unlikely to change that fact. It's true that there are more lucrative titles out there, but this isn't a bad game by any means and it's not difficult to see why some players enjoy diving below the surface and spending some time hunting for dolphin treasure.
