Dolphin Reef Slot Playtech

Dolphin Reef is a 20-payline video slot operating on the Microgaming software platform. Set underwater, the game’s wild card is the Dolphin, which only occurs on reels 2 and 4, and the scatter is the Treasure Chest icon. Players can test the slot on this page for free or choose any of the featured Microgaming casinos to play the game for real money.

Prior to diving beneath the sea surface and exploring the reef, players should adjust their wager. The number of active paylines is set by clicking “Lines”, while “Max” chooses all paylines. “Bet” alters the coin size from 0.01 to 5 and “Max” chooses the highest bet. Clicking “Spin” starts turning the reels and “Au­top­lay­” spins them for a preset number of times uninterrupted.

After any win there is an option to press “Gamble” and increase one’s winnings. If players choose the correct colour of the face-down card, their win is doubled and if they guess the suit of the card, it is quadrupled. Wrong guesses, however, lead to the end of the feature. Winnings may be gambled up to 5 times. To leave the round themselves and save their winnings, players should select “Take Win”.

In the Re-Spin feature players can win 5 held re-spins with expanded wilds when 2 Dolphin symbols emerge on reels 2 and 4. Reels 2 and 4 then expand and reels 1,3 and 5 are spun 5 times .

A jackpot of 5,000 coins will be won when 5 Clown Fish icons emerge on an enabled payline.

Dolphin Reef is a game I play from time to time whenever my balance allows it and whenever I don’t have any luck with my standard favorite Marvel slots.

This is a standard 20 payline 5 reel slot from Playtech with a few interesting features. I think this is the only game I know where 3 scatters only provide a bet win and don’t trigger any bonus round. I learned this the very first time I played this game. I was playing on minimum bet and went over 200 spins without hitting a bonus feature. I didn’t read the paytable so I was waiting for 3 scatters to hit. When they finally did I only got a 3 x bet win and thought there was something wrong with the game. I opened the paytable only to find out that the bonus is triggered when the dolphin symbol appears on reels 2 and 4. I was angry and didn’t want to wait any longer so I just moved to another game. Later on I played this game a few more times and had some descent wins on it so I started playing it more.

I like the bonus round here because you get 5 respins with stacked wilds on reels 2 and 4 so you have a chance to hit some nice 5 of a kind combinations. I almost get some descent win every time I get this feature. Another thing I like here is that the wild also substitutes the scatter symbol so you can get 4 or even 5 scatters in the bonus round. It would be better if 4 scatters paid 100 x bet instead of 10 and 5 scatter to pay 200 x bet instead of 100 but still you can have some descent wins.

My biggest win on this game in the bonus round was about 400 euros in Fly casino but I was lucky enough to get the bonus round on a high 5 euros bet.

Dolphin reef it is playtech online slot, it is quite interesting game to play, but unfortunately it is presented not at all casinos, not sure why but some places miss this game.

This game has 20 paylines and generally there is nothing special, but somehow this game is still interesting. Some kind of magic which nextgen using in their slots, which have nothing really great or new, but still very nice to play.

There is only two wilds at base game, and also very pity thing about scatters. We all know that usually scatters trigger something , and always wait something good when we get 3 scatters, but unfortunately at this slot 3 scatters did not trigger anything, and basically just award some money. To trigger freespins feature you need to get dolhpin wilds at reels 2 and 4 at same time, they appear only at this reels, so you will not miss this moment when they appear.

So what does freespins give us? We got only 5 freespins, which can not be retriggered by anyway, but there will be 5 freespins with reels 2 and 4 wilds. Not bad at all, also taking a fact that both wild reels also substitute as 1 scatters, so if you get 3 scatters on other reels - there will be 5 scatters payout.

I think i like this game because feature trigered usually, and also when it finally come - it will pay at least something. Chances to get very low dissapointing payout are very small. My best result at this slot was 350$ dollars won at 1$ bet size after 5 freespins, and it is still can be higher if good paying symbols will make 5 of a kind.

Overall it is great and interesting slot to play. Variance here is not so high, so you will unlikely lose money fast without having few freespins feature = chances to have some nice wins.


Typical problem for online slots - base game is quite boring.

Dolphin Reef is definitely one of the coolest games out there. Once you give it a shot you cant help but like it. It offers great wins and great feature, which is pretty much all you want from a game. I have been playing it for years now and would say that I have been winning on it more that 80% of the time.

I first played this game on 888, and the minimum bet is €1. On that bet I have won over €300, and because of that recommend to play this game on high bets. You can still win good money on small bets, but if you are looking for huge wins you got to bet big.

The thing to look out for is the dolphins on the second and fourth reels. They award you with an awesome feature that not many other games offer. For five spins the second and fourth reels stay wild and give you a huge chance of getting big pay. My best result was over 300x, which is not big by this games standards.

The wilds also mix with scatters and you can get five scatters in free spins pretty easy. I got four of them many time and five of them only once.

The graphics, the sound effects and the theme are very nice and relaxing. As you play you feel yourself relaxing and enjoying yourself. I have spent hours playing this game, in fact I'm sure that many people who play this game are playing it for very long time.


The only thing that I would have like to see in this game is a stop button. I just like to double tap and for some reason believe that I would have been successful in this game. The reels spin so slow that I think I could stop it when I see it. Over all a cool game and one of my favorites. My rating 9 out of 10.
