Swedish provider Play’n Go is in deep water. In the upcoming game Mermaid’s Diamond we’re on a hunt for mermaids, diamonds and treasures. Let’s see if we find any…

We’ve mentioned this before and we’ll mention it again – yes, we’ve been a bit skeptical to PnG ever since we learned they are offering online casinos the possibility to set the rtp as they please themselves. Still within set parameters should be mentioned so you likely won’t get scammed playing a 70% rtp slot, but still. You do run the risk of playing a lower rtp version of the game at one casino compared to another.

With that said, PnG are known for some high quality titles and Mermaid’s Diamond has potential to be one of them. It does look very promising and we’re genuinelly looking forward for it to hit the casinos.

The game has 720 lines, 5 reels and the number of rows for each reel is 3-4-5-4-3, starting from both left and right. The game pays from both ways which is not unusual for a 720-ways slot.


Forget about the traditional boring J, K, A and Q symbols. Here instead you’ll be diving for fairy tale sea creatures and shiny stones. The less valuable symbols are made out of a stingray, starfish, squid and shells. The premium symbols as can be seen in the picture below concists of a diamond and red, blue and green rubin. It almost seems like the guys at PnG have been a bit lazy and borrowed directly from NetEnt’s The Secret of Atlantis.

The wild symbol is represented by a mermaid which substitutes for all symbols except the scatter.


There are two random features in Mermaid’s Diamond. One is the Trident Wilds feature. It activates randomly and can add wilds to 1 or 2 reels, depending on your luck. This is a pretty common feature in the world of casino which you have likely already come across on other games and unfortunately in our experience these kind of wilds are usually placed strategically on the worst possible positions. We hope it will be different here and that this feature will have true value and not just implemented as a heart stopper.

The other function is the Divine Intervention. On non winning spins showing 4 scatters the final scatter need to trigger the bonus could “magically appear”. This can be helpful as the bonus otherwise would seem too hard to trigger…

The Bonus Feature

…because to trigger the bonus you need 5 scatter symbols (treasure chests), one on each reel. If you do manage to trigger the bonus you get to pick one chest out of 5. Between 10 and 25 free spins lies hidden in the chests so make sure you’ll pick the right one…it’s not pre determined, we promise 😉

It’s also possible to get re-triggers in the bonus which can be achieved by landing 3, 4 or 5 chests. Land 3 chest and you’ll be awarded 3 extra spins, land 5 and you’ll get…yeah, you do the math. The game info states that there is no limit in the amount of spins you can have in the bonus so there is certainly room for some insane wins it seems.

Throughout free spins, each diamond symbol landing on the reels is collected. Every time 5 diamonds have been collected, at least one full reel will be filled with wild symbols.


The max win on any single spin on Mermaid’s Diamond is is an impressive 5000x, which is on the level of Book of Dead. The rtp on this game is 96.5%…if you are playing on a Malta licensed casino that is.

While we’re not the biggest fans of PnG and still waiting for them to win our hearts over, this does look very promising. With the possibility of endless retriggers in the bonus, extra wilds and a large amount of pay lines going both ways it’s obvious this can pay. We believe this game will see a lot of action once released and a whole bunch of big wins uploaded to Youtube once the casino streamers get their hands on this.

It’s not yet clear at this point when Mermaid’s Diamond will be released but you can be sure to find it on any of the large online casinos hosting PnG slots such as Vera & John, Betspin and Chancehill.
