Under The Sea

An octopus stands guard over the reels in Under The Sea, a Betsoft underwater slot where the Treasure Chest scatter doubles as a pick-em bonus entry and the Octopus Wild stitches paylines together across the 25-payline grid. Medium volatility, 96.4% RTP, and a layered bonus structure built around a free spins round with multipliers make this a solid online slot for players who want feature variety without extreme variance. Desktop and mobile compatible at Wild.io.

What is Under The Sea?

Under The Sea is a 5x3 video slot from Betsoft with 96.4% RTP, medium volatility, and 25 paylines. The Octopus Wild substitutes for all standard symbols while the Treasure Chest scatter triggers both free spins with multipliers and a pick-em bonus game.

Betsoft built this around an animated underwater world with a cast of sea creatures that have distinct visual personalities: a blonde mermaid figure tops the paytable, followed by clown fish, ornate tropical fish in varying colors, a clam holding an oyster, and the shipwreck itself as a recognizable set piece. The bonus structure works in two directions: the free spins multiplier path rewards sustained scatter landings while the pick-em bonus game gives players a more interactive stop between standard spins. The 25-payline setup with medium volatility means the game sits comfortably between a grinder and a feature chaser.

Under The Sea Slot Theme & Graphics

Under The Sea puts you 20,000 leagues down, with deep blue backgrounds, coral formations framing the reels, and ambient underwater lighting that shifts during bonus events. Betsoft applied its 3D rendering to each symbol with care: the clown fish has the oversized eyes and comedic proportions you would expect, the mermaid character has a detailed design that elevates her to lead symbol status, and even the low-value fish have enough visual variation in color and body shape to not feel like the same asset reused.

The shipwreck in the background is a recurring ocean slot device but Betsoft uses it as an active story element rather than decoration: it appears as both background set dressing and a mid-value payline symbol, tying the visual environment into the mechanical layer. Sound design runs with a soft sonar pinging rhythm in the base game and switches to a more animated track when bonus features activate.

Under The Sea Slot Symbols & Paytables

The paytable in Under The Sea maps directly to the underwater cast, with each symbol's value tied to its prominence in the scene. Understanding the symbols helps clarify when the Octopus Wild is doing the most work for you.

Low Value Symbols

The low-value tier is populated by a variety of colorful fish in blue, orange, grey, and flatter blue variants. These four fish types are distinct enough in color and shape to tell apart on the reels but all pay in the lower bracket for 3, 4, or 5-of-a-kind combinations on a payline. They land frequently given the medium volatility, keeping the base game from going long stretches without a return. The clam with oyster symbol and the shipwreck symbol bridge the gap between the pure fish icons and the higher-value characters above them.

High Value Symbols

The high-value tier starts with the green fish at 300 coins for five of a kind and the yellow fish at 200 coins for five of a kind. The clown fish, rendered with Betsoft's signature exaggerated proportions, sits above those. The blonde mermaid character is the top regular payer at 400 coins for five of a kind, she appears as the most humanized character in the symbol set and her presence across a full payline with the 25-payline format represents the single biggest regular win available outside the bonus.

Special Symbols

The Octopus functions as the Wild symbol, capable of substituting for every standard symbol on the reels except the Treasure Chest scatter. When it lands mid-combination it can turn a three-of-a-kind into a five-of-a-kind by filling the gaps between matching symbols on a payline. The Treasure Chest is the scatter and the gateway to both bonus paths in the game. Three or more Treasure Chests anywhere on the reels simultaneously trigger the free spins round with multipliers. They also activate the pick-em bonus game, where you select from a set of chests to reveal prizes: each chest contains either a cash award or the collect symbol that closes the bonus and credits your total.

Under The Sea Bonus Feature & Special Features

Free Spins with Multipliers

Three or more Treasure Chest scatter symbols landing anywhere on the reels trigger the free spins round. During free spins, multipliers apply to all winning combinations, increasing the value of each payline hit beyond its standard rate. The Octopus Wild remains active during the round, so any Wild-assisted combination benefits from both the substitution and the multiplier at once. Retriggers are possible if additional Treasure Chest scatters land during the free spins phase, extending the round. The combination of an active Wild, multipliers, and the possibility of retriggers makes this the primary variance-generating event in a slot that otherwise sits in medium-volatility territory. For players tracking RTP, this is where the 96.4% figure is largely built.

Treasure Chest Pick-em Bonus

When three Treasure Chest scatters land, the game also opens an interactive pick-em bonus game. Players are presented with a selection of sunken treasure chests and choose from them in sequence. Each chest reveals a cash prize or the collect symbol. Selecting a cash prize adds that amount to your running total for the bonus round and presents the next row of chests. Landing on the collect symbol closes the bonus and credits all accumulated prizes. The pick-em structure gives players a sense of agency within the feature and the sequential reveal creates a natural progression: early chests tend to show cash while the collect can appear at any point. This mechanic separates Under The Sea from slots that funnel all bonus action into a single free spins path.
