Dark Waters Power Combo is a pirate-themed slot game that is set inside a cave. In the background, the ship that battled all weather to get you here to face the 4x6 slot layout. The music is a sweeping, grandiose epic of strings and drums fitting of a voyage into the unknown ocean.
The slot is awash with pirate-themed symbols. This includes the Wild map, skull coins, jewels, an anchor, pistols, a pirate hat, knives, and a bottle of rum. These are just some of the symbols featured in the game to help you formulate wins. Dark Waters Power Combo is also a Ways to Win game, which means there are no paylines. Because this is a 4x6 slot, there are 4,096 possible ways to win.
Well, it’s a good game, and it would make my top 10 in this genre. However, it’s not a slot that changes how the game or genre is viewed. There is a lot that could have been added to take this game up a level.
Winning is formed by matching 3 or more of the same symbols across adjacent reels, going from left to right. No matter how they land, as long as there is no gap in the rows, this is how winning payouts are created. The lower-ranking symbols of this game are the standard 10, J, Q, K, and A.
Before you spin any of the reels, you first need to decide how much you want to pay for each spin played. Select the coin stack image to reveal the prices. The game offers low betting at $0.20 per spin, and these prices rise to a maximum of $50 per spin. When set, you spin the reels of this game by pressing the large spin button. Alternatively, you can select the lightning-fast play or the auto spins button.
Above the reels, you will see three treasure chests: Giant Reels, Multi-Collect, and Golden Reel. These features are triggered by token symbols, which are represented by the jewels (the chest color matches the jewel color). Landing such symbols can trigger the free spins bonus, in which the feature will also be activated.
Bonus rounds are played with free spins, so you are not losing any money from your balance at this stage. Let’s look at the perks of this gameplay in closer detail.
Let’s begin by looking at the three chests and their features.
Giant Reels: During the free spins round, the reels and layout of the slot expand to a 6x6 gaming grid with up to 46,656 ways to win.
Multi-Collect: When Collect symbols (flaming skull and crossbones) coincide with Money symbols (skull coins), their values are collected by the player.
Golden Reel: Each free spin played is done so with a random reel that will only contain money symbols.
In triggering the free spins, you may land 2 different jewel tokens, and thus, you will play with two different features. The same can also be said if landing all three jewels and activating the free spins bonus. When the bonus is activated, 10 initial free spins are awarded. During play, you can re-trigger features, and in doing so, you can earn 3 free spins.
There is no hiding the fact that Dark Waters Power Combo comes with a selection of jackpot prizes. Mini, Minor, Major, and Mega. The return is relative to your bet per spin size. Mini returns 15x the bet. Minor returns 40x the bet. Major will return 200x what you bet. The Mega jackpot is a huge 5,000x your wagering bet.
The perks of play can only happen by engaging with the base game, as Dark Waters Power Combo does not come with a Bonus Buy feature.
There are a few good pirate-themed slot games online. Though, I’m not entirely convinced that one has been made that can be deemed as a game-changer. Nevertheless, it is a theme I will show interest in, and with the production backed by Games Global, which supports Just For The Win as the main developer, it’s a team combo that rarely fails to impress.
The design is simple, and the slot suggests plenty can happen during play. So, I set my wagering bet per spin to $2 and set up the Autoplay option to spin 50 goes. During play, I triggered the Giant Reels and the Multi-Collect free spin bonus on my first spin. The chests burst into flames as they explode open with the slot covered by a flaming black banner that present my reward of 10 free spins.
The game took on a new dynamic when the reels expanded, and the animation of burning embers began to rise into the air from below the slot. The total win from the free spins round was $56.80. With 40 spins played, I then landed the Golden Reel feature with 10 free spins. This was possibly the better of the features, as with this alone, I collected a win amount of $38.00
After the 50 spins I played, I had won enough to end with $53.20 more in my balance. What an experience that was. Lots are happening, and it is enjoyable to see it unfold.
The maximum that you can win when playing Dark Waters Power Combo is $250,000. To hit this sum, you will need to play at $50 per spin. The Return to Play rating comes in at 96%, and the volatility setting is high. Unsurprising when a quarter of a million can potentially be won.
Dark Waters Power Combo by Just For The Win is a fun game. If you’re the kind of player who likes their slots packed with in-play features, then this does not disappoint. The fact I hit the free spins bonus twice within 50 spins means I cannot cast fault on this game. But is it up there with the best pirate-themed slots online?
Well, it’s a good game, and it would make my top 10 in this genre. However, it’s not a slot that changes how the game or genre is viewed. There is a lot that could have been added to take this game up a level.
Still, I recommend you play Dark Waters Power Combo, along with these other fantastic pirate slots:
Pirates’ Plenty Megaways by Red Tiger Gaming
ARRR! 10K Ways by Yggdrasil
