Sea of tranquility

Sea of Tranquility

WMS released this 30-line online slot game in September 2014. The Close Enough Feature is a unique aspect of this serenely themed Slot Game. The experience of playing Sea of Tranquility is quite tranquil unless, of course, you’re losing.

Sea of Tranquility Characteristics

The Slot includes a variety of symbols including owls, fireflies, a peaceful maiden, ships, wild comets, alpha numeric symbols among others including the moon bonus symbol. The reels have a unique shape which not only adds to the visual experience but is the basis of the ‘Close Enough’ feature plus the audio just may either put you to sleep or inspire a visit to the spa. Wager as little as $0.30 or as much as $150 per spin.

Special Features

The wild comet substitutes all symbols except for the bonus moons. The wilds expand turning the entire reel wild.

If you’ve ever played a Slot Game and cringed because a symbol just rolled by the active payline, you’re in luck with Sea of Tranquility. The Close Enough feature comes into play when the wild symbol appears in the extra bit of space at the top or bottom of each reel. It may not be on an active payline but it’s ‘close enough’ and the wild will expand to fill the entire reel.

The free spins bonus feature is triggered when two or more moon symbols appear. During free spins, the maiden, owl and ship substitute one another.

2 Moon Symbols = 7 Free Spins + 2x bet

3 Moon Symbols = 10 Free Spins + 5x bet

4 Moon Symbols = 20 Free Spins + 10x bet

5 Moon Symbols = 40 Free Spins + 25x bet

The free spins bonus may be re-triggered when two or more moon symbols appear on the reels.


In comparison to the range of online themes from WMS, Sea of Tranquility leaves a lot to be desired. The theme isn’t as exciting as other titles such as Bruce Lee, The Wizard of Oz, Bier Haus and many more. With that said, there is potential to win big with the bet multipliers upon triggering free spins and the ‘Close Enough’ feature so give it a try and decide for yourself!

    lost all me coins nice slot average pay out 3 star
  • Sea of Tranquility is a decent slot. Like all slots from this provider are gonna be or too tight or giving big wins one after another. I like the graphics and the music is way too relaxing indeed. It is not one of my favorites but i throw some spins here from time to time although i have never won anything big.

    The overall look of the slot is a bit messy and confusing. What does the planets on background have to do with the main theme of this slot (Sleep) Don't like the reels with weird linings and shady gray are on them. As the other has stated the audio is very calm and relaxing and i cant recommend this slot to be played on the evening as you might get very sleepy,(Or maybe you do wanna play this if you have troubles to get sleep) Payments are very low and i can assume from it that this slot has pretty low variance and could be good to wager any bonuses. Free spins are very easy to trigger and i like the close enough feature of this slot. In the end this slot really cant make a big rating in my books , its bit too relaxing and calm and i want slots to packed with action and very big wins. Feel feel to fell asleep at

    I agree with Raptordinos, this is a cool game with plenty of wilds and good features. I like it and will play again.

    I don´t understand why this slot has not more comments here, its design is good and sound effects transmit a kind of calm that makes of this one a very relaxing and cool game, and winnings are not worse, at least that was my impression playing it for fun, since wild was a very active symbol and triggering free spins was not a hard task for me. I think this slot deserves to be tested.
