Quick verdict: Dolphins Treasure is a 2015 Evoplay slot with 5 reels, 9 fixed paylines, a 94.1% RTP and low volatility. The dolphin wild doubles any win it joins, 3 shell scatters give 10 free spins that can retrigger, and a separate shell-picking bonus pays coin prizes. It is not Aristocrat’s land-based Dolphin Treasure, which is a different game from the mid-1990s.

What is the Dolphins Treasure RTP?
The Dolphins Treasure RTP is 94.1%, so the house edge is 5.9%. That is below most modern slots: Aristocrat’s Dolphin Treasure is listed at 94.88% by slot databases, and many current games sit around 96%. Low volatility softens it, because about one spin in three pays something, but over time you lose more per spin here than on a 96% game. If RTP is your priority, our highest RTP slots list is a better place to start.
How Dolphins Treasure works
The reels show sea creatures and card values on 9 fixed lines. The dolphin is the wild: it stands in for every symbol except the scatter and bonus symbols, and any win it completes is doubled. Low volatility means the game pays small amounts often rather than saving up for big hits.
How do you trigger the free spins in Dolphins Treasure?
Land three or more shell scatters anywhere for 10 free spins. More scatters during the round retrigger it, so the feature can run longer than 10 spins. The game has a second feature as well:
- Free spins: 3 or more shells anywhere, 10 spins, retriggerable.
- Shell bonus: 3 bonus symbols on reels 2, 3 and 4 in the base game open a screen of closed shells. Pick shells for coin prizes until you open an empty one.
- Double up: after a win, most versions let you gamble it on a guess to double it, or collect.
Dolphins Treasure vs Aristocrat’s Dolphin Treasure
| Feature | Dolphins Treasure (Evoplay) | Dolphin Treasure (Aristocrat) |
|---|---|---|
| Released | 2015, online | Mid-1990s (1996 or 1997), land-based |
| Lines | 9 fixed | Up to 20 (a 9-line version also exists) |
| RTP | 94.1% | 94.88% in slot databases (venues can set their own) |
| Wild | Dolphin, doubles wins | Dolphin sunset, doubles wins |
| Free spins | 10, retriggerable | 15 free games, all wins tripled |
| Extra bonus | Shell-picking game | None (a colour or suit gamble) |
| Free demo online | Didn’t load on our site when we tested it on 7 Oct 2026 | Rarely; most slot databases list no demo |
If you remember 15 free games with tripled wins from a machine in a land-based venue, that was Aristocrat’s game. It is hard to find online, and we know of no demo we could link.
Tips for playing Dolphins Treasure
- Watch reels 2, 3 and 4 for the bonus symbol: the shell-picking game only starts from those three reels, and only in the base game.
- Skip the double-up if you want your session to last: low volatility is the game’s strength, and gambling small wins turns it into a high-volatility game.
- At 94.1%, this is a game to play at small stakes. For real-money play, a higher-RTP ocean slot keeps more of your budget.

Where to play Dolphins Treasure
Dolphins Treasure is an older Evoplay title, and Evoplay’s own game list no longer shows it, so many casinos will not carry it. Search the lobby for Evoplay and the game name before you deposit.

If the game isn’t there, Dolphin’s Pearl Deluxe is the dolphin slot most lobbies do carry.
