About Underwater Riches Slot 

FBM are expanding their portfolio of online slot games with their latest underwater instalment called Underwater Riches. This title plays on a standard 5x3 grid with 50 active paylines. When it comes to winning combos, you know the drill. To win, you need to match at least 3 symbols on a payline, starting from the leftmost reel.
You can join this exploration by placing your bet per spin. In the Underwater Riches slot, bets range from £50 to £1000 per spin, so make sure you’re comfortable with relatively high stakes per spin before you spin those reels. You can adjust your preferences by pressing the + and – buttons in the level bar below the grid. Since the game has 50 paylines, you’ll have the chance to land 50 different winning combinations in the base game.
FBM has packed the Underwater Riches slot with a few in-game features and bonuses. The action revolves around the scatter symbol that triggers the Free Spins round. Also, we have the common wild symbol that serves as a substitute to form a win, capped at a maximum of 5,000x your bet.

Design, Symbols and Graphics 

As the title suggests, the Underwater Riches slot is inspired by the sea world and the underwater life and landscapes. As soon as you start the game, you’ll notice that the design is pretty clean and straightforward, with reels being in the centre of attention. The background is a bit blurry as if you are diving underwaters. Overall the animations and sounds are pleasant and contribute to the atmosphere, with curious, mysterious feels to them.
On the reels, you’ll find different symbols complying with the underworld theme. Here we have A-J royals along with the ship’s wheel, diving helmet, shell, trident, green sea creature, octopus and merman and mermaid as bonus symbols. The merman symbol is the wild symbol here, appearing everywhere except on reel 1. He helps in creating winning combinations and also appears during the Free Spins round to boost your wins. The wild appears only on reel 2 and 4 during Free Spins. The mermaid, on the other hand, is the scatter that triggers the Free Spins.

RTP, Variance and Payouts for Underwater Riches Slot 

The Underwater Riches slot comes with an RTP of 96%, which is straight up the industry average. In addition, the game’s variance is medium, meaning that you can expect frequent and smaller wins during the base game. Therefore, the Sinbad slot is suitable for players that don’t want to take huge risks and prefer medium over high volatility. Be careful with your bets, though, since it’s quite unusual for a slot to offer such a high and risky level of stakes.  If you want to learn more about different slot models, check out our guide about Variance, Volatility and RTP in online slots.

Gameplay and Features on Underwater Riches Slot 

When it comes to bonus games and features, the Underwater Riches slot is pretty simple and straightforward. Along with wilds that help you to form a win, you have the scatters that trigger the Free Spins round. So, let’s see how does this game work here in more detail: 

Free Spins

This feature is triggered as soon as you land 3 or more mermaid scatters in a spin. The more scatters you land, the more free spins you get. So, for 3,4 and 5 scatters, you’ll win 8, 10 and 12 free spins, respectively. During this round, wilds also appear on the reels, helping you to land a win. Moreover, the feature can be retriggered by landing another round of 3 or more scatters.

Underwater Riches Slot on Mobile 

The Underwater Riches is optimised to play on all devices, including mobile. The game is developed with HTML5 and will perfectly load on any smaller screen and any operating system while keeping the same quality in terms of design and gameplay.
