Overall Opinion about Under Water

I was eager to try this game because of its similarity to RTG’s Mermaid Pearls slot game which I enjoyed playing. Under Water game is a bit older than Mermaid Pearls, but the graphics were pretty captivating, so I was impressed from the start. While players on some gaming forums had complaints about the gameplay, I didn’t encounter any such issues. However, I did have a hard time landing winning combinations. Besides the long dry run in the base game, the action took off in the Bonus Rounds. I did place really low bets, so I didn’t win much in the end, but the game will be more generous for players willing to place higher stakes.

Under Water Theme and Unique Features

Just like the Goonies slot machine, the Under Water slot game features 5 reels. Accentuating the title, there is an under-the-water game setting accompanied by a soundtrack the captures perfectly the sound of water bubbles – it’s smooth and calming to the ears.

The game reels and rows are reminiscent of what you should expect with the Mermaid Pearls slot game. They include a Shark, Dolphin, Octopus, Stingray, Crab, and Swordfish. Also, players will see some regular card symbols ranging from A, K, Q, J, 10, and 9. All symbols have a geometric form and are rearranged after every spin.

Players can win 1,000,000 coins in the BonusGame.
