Designed by 1×2 Gaming, Under the Waves affords US players the chance to take an adventure deep under the sea. If treasure and deep blue seas get you excited then this is the perfect online slot to play as you are presented with mermaids, fish, and turtles throughout your gameplay. Let’s take a look at Under the Waves’ features, how to play, and similar games.

How to play

From the start, the player is immersed in a colorful underwater world filled with all sorts of sea creatures. Under the Waves has 5 reels, 3 rows, and 30 fixed paylines. This online slot machine plays from left to right, starting from the far left reel, and three-of-a-kind is the minimum for landing a winning combination. The minimum bet you can place is $0.20 and bets can go as high as $100 per single spin. Quickspin mode allows you to speed up the reels and if you get tired of hitting the Spin button, you can activate the Autoplay mode for up to 99 automatic spins. Under the Waves has an RTP of 96%.


Under the Waves features mesmerizing graphics. This video slot dazzles players with deep-sea crisp graphics and a fitting soundtrack. The bright and colorful design keeps you intrigued and makes the gameplay so much more entertaining. The theme of this online slot machine allows you to explore the ocean with fish, treasure chests, shipwrecks, and beautiful mermaids. The cartoon imagery is accompanied by a tranquil but rather catchy soundtrack. The symbols in Under the Waves include turtles, manta rays, pufferfish, and sharks. These animated sea creatures make the game even more entertaining!


Under the Waves’ reels showcase a wide variety of ocean dwellers. You are presented with a total of nine ocean creature symbols including flatfish, sharks, octopi, pufferfish, and turtles. The mermaid symbol represents the wild and it can replace all the other symbols to form a winning combination. In addition to the sea creatures, there are two scatter symbols — the shipwreck and the treasure chest — which is responsible for delivering several other cool features in this online slot. 

Bonuses & jackpots

There are great free spins and bonus games to unlock in Under the Waves. If the shipwreck scatter symbol appears three, four, or five times on the reels, you could win 10, 14, or 18 free spins. What’s great about this free spin feature is that you’ll get wild symbols that stay for two rounds, instead of only one round, as in the base game. So, if you land a mermaid symbol during the free spins round, it becomes a sticky wild and locks in place for any remaining free spins you have left.

The bonus game in Under the Waves is known as a classic Pick Me round. Players can activate it by landing three, four, or five treasure chest scatter symbols during the same spin. After you land the treasure chest scatter symbols, you’ll get to select treasure chests that will reveal instant cash prizes. The more scatters, the more picks you’ll get!
