Dolphin Reef graphics and design

Dolphin Reef is a chipper take on sea life, with a sea turtle, seahorse, starfish, and clownfish as the premium symbols. The tentacle-bearing treasure chest serves as the scatter symbol, and cheerful, chattering dolphins are the wilds. Reel spins are accompanied by the soothing strum of a harp and interjected with sea-related sound effects, such as splashes, bubbles, and playful dolphin chirps. Dolphin Reef is a fun game with a classic slot feel.

How Dolphin Reef’s bonus features work

Dolphin Reef approaches bonus features a bit differently than other slots. Rather than having a separate free games feature, the dolphin wilds trigger respins.

Dolphin wilds

Dolphin wilds can only appear on reels two and four and stay in one position when there’s only a single wild. When two dolphin wilds appear, reels two and four expand into wilds made up of pools of seawater, and the respin feature is triggered.

Respin feature

During the respin feature, reels one, three, and five respin five times, while reels two and four lock into place as expanded wilds. The dolphins jump back and forth between the two reels for the duration of the free spins.


The treasure chest scatter pays out at the following rates:

  • Three chests: 3x the total bet
  • Four chests: 10x the total bet
  • Five chests: 100x the total bet

The dolphin wild can substitute for the chest scatter.

Five-of-a-kind of the clownfish pays 5,000 times your pay-line bet, so a full screen of clownfish would give you a max payout of 5,000 times your total bet.

Final thoughts on Dolphin Reef by NextGen

Dolphin Reef is fun to play and is reminiscent of a classic slot. The music and sound effects are enjoyable, and the graphics are well done. The slot’s old-school feel may not appeal to those who prefer slots with modern graphics and movie-quality sound design. The main feature missing are multipliers, which would really add to the bonus features. Taking all of that into consideration, we give Dolphin Reef a rating of 7/10.
