Sirens, these mythical creatures with angelic voices and the worst intentions, have been fascinating seafarers for centuries. Most people confuse sirens (creatures with women’s faces and bird bodies) and mermaids (creatures with the upper body of a human and the lower body of a fish). This is probably the case with the people who game “Siren’s Cove” its title: this High 5 Games slot machine has no bird bodies anywhere. But the mermaids on its reels do have wings, so that’s at least a step in the right direction.

While Siren’s Cove does have its myths a bit mixed up, this doesn’t make it any less appealing as a casino game.

How to Play Siren's Cove

Siren’s Cove has the same interface on desktop devices and smartphones – if you play it in landscape mode, of course. The interface may seem a bit counterintuitive, and it’s not easy to navigate if it’s your first time playing slots from High 5 Games. There’s a circled + in the top right side of the screen, where you can find the sound settings, and the pay table, while clicking on the bet amount per spin will reveal your options for a stake. Note that while you stake a certain amount per spin, your winnings will be calculated based on the amount per line. So, if you stake $100 per spin, this translates into $100/20=$5 per line.

On the right, you have the large Spin button, with the speed modifier above and the Autoplay button below it. With the speed modifier, you can switch between normal and fast speed. At normal speed, the game may be a bit too slow for some players. At fast speed, in turn, the spins are almost instant, which can take the fun out of the game.


The game has quite a large number of symbols. As you might expect, most of them are low-paying ones. All low-paying symbols will award you a win for at least three of them on a win line. The payouts below are the maximum wins for each symbol, for five matching ones on a win line.

Siren's Cove paytables

Low-paying symbols

  • 10, J, Q, K, and A symbols borrowed from poker cards, will pay out 12, 14, 16, 18, and 20 times your bet per line. 

High-paying symbols

  • Orange Siren pays 80 times your bet per line
  • Pink Siren pays 120 times your bet per line
  • Blue Siren pays 160 times your bet per line
  • The ship’s Captain / Pirate pays 200 times your bet per line

Siren's Cove bonus wildSpecial symbols

  • Wild symbol which substitutes for every other symbol on the reels, except for the Bonus symbol. It also has the highest payout for any winning combination, with up to 1000 times your bet per line for five matching symbols on the reels.
  • Bonus symbol that only appears on reels 2, 3, and 4. It doesn’t have a payout associated with it in the game’s pay table. It triggers the game’s Free Games Bonus.

All the symbols on the game’s reels are stacked, and for each spin, there’s one symbol that’s Super Stacked. At the beginning of each spin, a symbol is selected at random by the game that will cover the entire reel. This includes the Wild and the Bonus symbols as well. The payouts associated with the symbols are the same in the base game and the Free Games Bonus.

Once you have your game set up, and your bet per spin selected, you can proceed to the main game.

Please note that “n/a” means that the specific symbol does not result in a payout for that particular combination.

Siren's Cove Payout and Volatility

Siren’s Cove is a high-volatility slot machine with a return to player (RTP) of 95%. This puts it right at the industry average. The smallest amount you can win with one spin is equal to your stake, while the highest amount is 1000 times your bet, paid by five Wild symbols on the same win line.

The game is also connected to High 5 Games’ Rapid Rewards progressive jackpot network – but only in certain South African online casinos. This means that the highest payout it can award is much higher. The Minor jackpot pays out a smaller amount, usually around $10 or below, once every hour. The Major jackpot can be as high as a few thousand dollars, with one guaranteed payout every day. And the Grand jackpot is the highest, with a top prize that’s continuously growing.

Siren’s Cove Graphics

The game is pretty young – it was released in February 2022. As such, it has graphics that are on par with other modern casino slot machines. The characters on the reels are almost photo-realistic (except for the wings and the fishtail, of course). But the game is low on animations – it will only show them when you win. Overall, the game is crisp, beautifully crafted, and it doesn’t become monotonous too fast.

Siren’s Cove Special Features

The game has a special feature called Super Stack that activates automatically both in the base game and during free spins. Normally, the symbols are stacked on the game’s reels. But at the beginning of each spin, one of them becomes Super Stacked. One of the reels, selected at random, gets a larger “super stack” of special symbols that is transformed into one of the game’s symbols, also selected at random. This can be anything from 10 to the Bonus symbol, including the Wild. This can help you trigger bigger wins both in the base game and during the bonus games.

Siren’s Cove Mobile Option

Siren’s Cove is not only mobile-friendly – judging by its user interface, it’s “mobile-first”. Its controls are very simple, perfect to be played on smartphones with touchscreens. It’s perfectly playable in portrait mode, it doesn’t get crammed or distorted like some other online slots. And in landscape mode, it offers the perfect mobile slot experience. 

The game loads fast on smartphones and runs smoothly even on older models.

Siren’s Cove Bonuses & Free Spins

Aside from Super Stack, Siren’s Cove also has a Free Games Bonus feature. The Bonus symbol in the game only appears on reels 2, 3, and 4 in the base game. To trigger the game’s Free Bonus Games feature, you’ll need 9 of them to cover reels 2, 3, and 4. When this happens, you’ll need to select one of the nine fields on the screen to reveal a symbol that will be Super Stacked during the free spins. When this symbol is decided, you can begin your 7 free spins.

The free spins are played with an alternative set of reels, without the Bonus symbol on them. The payouts associated with the symbols on the reels are, in turn, the same. The free spins can’t be retriggered. 

Should You Play Siren’s Cove?

Siren’s Cove is a beautiful game, with state-of-the-art graphics and an overall good atmosphere. It can be a fun game to play even if you do it casually, and even if you play it free. It also comes with a high maximum bet, a free spins feature that’s triggered relatively often, and stacked symbols, which gives it the potential for big wins. This makes it a great choice for high-rollers, too, with big budgets and a lot of patience.

Can I play Siren's Cove for real money?

While High 5 Games is not the most widely used casino game provider, its games are available at South African online casinos. Note, in turn, that in most cases, it will likely come without the High 5 Games jackpot that is reserved for select online casinos.

Of course, you can. While it is a high-volatility slot machine, Siren’s Cove pays out quite often. The best thing about it is that you can play it for very low stakes, and also with just a limited number of active win lines. With a stake of just 0.01 coins per line (0.05 or 0.2 coins per spin), even a small stack of coins can ensure hours upon hours of play. 

On the other hand, if you feel like taking higher risks, you can play the game as a high-roller. You can spend as much as 1000 coins on each spin. In this case, your risk is much higher – but when the wins come, they will also be big.
