Here is a quick line up of the game’s basic facts.

Deep in the blue sea are different sea creatures promising fortunes and great wealth if you can find them. Led by the charismatic dolphin, these creatures, comprising sea turtles, star fish, sea horse and angel fish are all willing to gift you jewels worth thousands of dollars.
Dolphin Treasure slot machine takes you into the deepest of waters, showing you a different world as rich as the one you know on land. The game has a unique and refreshing feel to its delivery but maintains the traditional Aristocrat line betting design style.
If you love the seas, and especially cherish the thought of fishing during the sunset, then this game is perfect for you because the biggest wins come just before dark.
The graphics of Dolphin Treasure slot machine looks a bit dated, a deliberate move by Aristocrat to create a classic vibe for players. For us, the attempt is a hit in terms of simplicity but we do feel that it could be more animated. However, that is just us.
On starting the game, you instantly enter the 5×3 grid, where each reel stands alone like a vertical paper rectangle. At both sides of the grid are a line of numbers, each representing a payline, while at the bottom are different icons.
Like we formerly stated, this slot is not very big on animation. However, whenever you land wild wins, the dolphin jumps into the reels to make its presence known. Also, animated boxes and lines are visible following combinations.
If you have played Aristocrat’s Dolphin Shell, then the Dolphin Treasure slot machine is more like an advanced twin. Their gameplay is very similar and simple. Firstly, you need to launch the slot and determine your bet before spinning the reels.
You form win combinations by matching 11 regular symbols in any of the active 20 betways. These regulars are divided into two categories – 5 high-tier symbols, comprising sea creatures and 6 low-paying card characters. Generally, you need to land 3-of-a-kind to 5-of-a-kind similar symbols on active lines to win. Though a few characters trigger payouts for 2-of-a-kind as well.
There are also two distinct bonus characters that can also trigger wins. The wild presented as a sunset pays up to 9000 coins when 5 of a kind lands on a payline. It also has the ability to substitute regular symbols and complete wins except the scatter. The scatter has multiple functionalities and we will explain more about it in the next section.
The table highlights how each symbol pays in coins.
| Symbols | 5 of a kind | 4 of a kind | 3 of a kind | 2 of a kind |
| Sunset (wild) | 9000 | 2000 | 200 | 10 |
| Sea Turtle | 750 | 100 | 25 | 2 |
| Sea Horse | 750 | 100 | 25 | 2 |
| Star Fish | 400 | 100 | 15 | – |
| Octopus | 250 | 75 | 10 | – |
| Angel Fish | 250 | 50 | 10 | – |
| A | 125 | 50 | 10 | – |
| K | 100 | 50 | 5 | – |
| Q | 100 | 25 | 5 | – |
| J | 100 | 25 | 5 | – |

A proper, Aristocrat design, Dolphin Treasure casino slot game boasts an impressive bonus collection that enhances your winning potential. We take a look at each one and their specific roles.
Wild: Apart from the substituting regular symbols in active lines, the Sunset wild also doubles the expected payout. This ability is quite vital in setting off massive cashouts during the bonus game
Scatter: The Treasure chest is the scatter and the main catalyst for activating the free spins bonus game. You just have to land at least 3 of it anywhere on the reels simultaneously and the 15 FS bonus round will immediately become active. However, before you start the round, the scatter will also pay you based on the number of appearances on the base reels.
Free Spins Game: You enter the bonus game with 15 spins, where every win combination is multiplied by 3x. The 3x multiplier also applies to 2x wild-substituting wins, giving players a real chance to score massive payouts.
Gamble Feature: Everytime you land a win, Aristocrat presents an option to gamble your payouts. The gamble proposal is simple. You have to make a choice to gamble on card colors or suits.
2x Color Gamble – You have to choose whether a hidden card has a Red or Black color. A correct guess doubles your wins while a bad guess leads to a total loss of payouts.
4x Suit Gamble – for this one, you have to correctly guess the suit of a hidden card. You receive a quadrupled value of your initial payout if correct and lose it all if the guess is wrong.
We have no direct advice regarding when to use the gamble feature. Instead we will leave you with this Kenny Rogers’ Gambler line «Every gambler knows the secret to surviving is knowing what to throw away and knowing what to keep. Cause every hand is a winner and every hand’s is a loser» Basically, the message here is to only gamble when you don’t mind much about the outcome going sideways.
One of the most tricky parts of the Dolphin Treasure casino slot game is accurately placing a bet. The design expresses its currency value in coins or credits instead of dollars. We will break down this process, so you know how to place a wager.
Now, the slots allow line betting, allowing you to determine the numbers of paylines to activate, starting from 1 to 20. So the first step is to determine your coin size by adjusting your ’Bet Per Line’ with the relevant ’– and +’ menu. The coin’s size starts from $0.01 and peaks at $2.50. Choose the appropriate value that matches your budget.
The next step is to select the number of paylines to activate by adjusting the ’Lines’ menu.
Afterwards, multiply your selected coin size with the number of activated paylines to determine your overall bet amount. Of course, the system will complete this sequence automatically and show your overall bet value just under the grid.
Based on the above calculation:
The payout terms for this slot are simple enough. The most rewarding symbols pay the best and you have a higher chance of attracting them when you activate all 20 paylines. Also, when you form a win combination, you only receive payout for the highest number of a kind in that particular payline. However, it is possible to trigger multiple combinations on different paylines with just one spin if lucky enough.
Aristocrat announced this slot RTP as 94.88%, which is actually surprising because we feel it is much better based on our real time experience. We did not have any difficulty forming wins and it was relatively easy to enter the bonus game. Strictly based on our experience after 200 spins, we would say the RTP is a bit above 96.5%. However, let’s work with the studio number for explanation purposes.
A 94.88% RTP means that casinos only have a 5.12% house edge. In simpler terms, casinos keep 5.12% of all players’ bets as their profit and pay out the rest to winners who enjoy combinations on the reels. Still, it is important to point out that each player’s experience may differ, especially those that only play for the short term.
Dolphin Treasure slot machine has a low volatility, and that may partly explain while we had a good outing on the reels. A low variance implies high win frequency with not-so-massive payout sizes. This fact is actually correct regarding this title. However, the experience totally changes when you activate the bonus round, which multiplies every combination by up to 3x.
You have to spin your way to wins in the Dolphin Treasure slot machine. There is no assigned jackpot and to be honest there is really no reason for one because the game’s symbols pay well. Players have a really awesome chance to trigger thousands in payout with virtually no real limit. Yes, you heard that right.
The provider does not have any official capped limit that determines a win. You can consistently re-trigger the free spins round, enjoy tripled payouts and make the most of very high paying symbols like the wild which pays up to 9000 coins on a 5-of-a-kind. Imagine hitting the 5-of-a-kind wild during the FS round at a coin size of $2.5. That would lead to a whooping $67,500 (9б000 coins x $2.5 x 3). Hit a couple of these more and you have more than a few hundred thousands at hand., a realistic reach for this title.
The Aristocrat team delivered a masterpiece with Dolphin Treasure, finding a way to link the soothing calm sea bed with wealth. We love the idea and also like the game payout structure. The symbols pay well and the bonus features are on point.
There really isn’t much to complain about this game apart from the fact that the studio has made it quite difficult to find Dolphin Treasure free pokies online. Recently, the studio withdrew the free version of many of its titles from online platforms. So, to play this title, you have to visit a partnering casino or slots hub and there aren’t really many of those.
Thankfully, FreeSlots99, a no games download hub, hosts the slot, allowing players to bet with real cash and earn wins. We also host thousands of slots from Aristocrat and other providers like Pragmatic Play and iSoftBet. Register with us and discover high paying machines with stacked wilds, free spins rounds and jackpots.
