Gameplay
Sea of Tranquility is relaxing, period. The slot features five reels and three rows with 30 fixed paylines that pay left to right. The game’s symbols include an owl, boat, fireflies, a sleepy cap, and a woman, who although shook by recent changes, looks excited about the decisions she has made in her life. I mean, you must be an absolute monster to not find these things pleasant. As far as sounds go, Scientific Games made sure this game wouldn’t be overly stimulating. It sounds like you are in a spa. Instead of the typical loud fanfare that accompanies a win, this slot lightly tallies your winnings with the grace of a ballet dancer at the Bolshoi. The game features a wild, that replaces all symbols except the bonus. It expands to fill the entire reel. The moon-shaped bonus symbol can award up to 50 free spins and 25x your bet when you spin two or more. You will also find the Close Enough engine, which rewards you for spins that miss paylines, but land in the “close enough” area on the reels. Any bonus or wild symbol that lands here will expand to fill the entire reel. For once, the world isn’t totally out to get you.

Conclusion – Benevolent Payouts
Scientific Gaming has really hit a niche market with Sea of Tranquility. This game is one of the few that is content to give players room to breathe. Instead of an over-the-top theme, equipped with flashing lights and loud noises, this slot is set on a cool, dark background that is pleasing to the senses. One aspect of the game that seems out of place is the water drop noise that plays as you scroll through the game menu. Last time we checked, single water droplets are used for torture and if you enjoy this sound, you may be a psychopath, but to each their own. So, take a voyage on one boat ride that won’t give you sea-sickness. Let us know how the game made you feel in the comment section below.
