Sea of Tranquility Slot Review

The Sea of Tranquility slots game can be found at online casinos offering WMS Gaming software who are a wholly owned subsidiary of Scientific Gaming. WMS Gaming do not publish their RTP or House Edge figures as standard. However UKGC licensed operators who now publish all game figures as standard. As such we can say that the House Edge of Sea of Tranqulity is 4.15%. As this figure has not been confirmed by the software provider we cannot confirm whether this game is configurable or not. As such this figure should be treated as a guideline only when playing at any operator that does not publish their RTP figures.

What mysteries does the sea of our moon hold?

Sea of Tranquility is a 5 reel game with 30 paylines.

The ‘Green Light’ symbol is Wild and expands to cover any reel it lands on.

There are two bonus features when playing Sea of Tranquility. The first bonus feature is active on every spin. Directly above and below each reel is a visible half symbol. If a Green Light Wild symbol or a Moon Bonus symbol land in these visible half symbols, they are considered to have landed on the relevant reels for triggering Wild reels or the bonus feature.

The second bonus feature is triggered when you receive two or more of the Moon bonus symbol in any position on adjacent reels starting from the left side of the reels. When this happens you will be awarded either 7, 10, 20 or 50 free spins depending on the number of Moon bonus symbols you receive. During the free spins the ‘Lady’, ‘Ship’ and ‘Owl’ symbols are considered Wild for each other and will pay in combination. Free spins can be retriggered.


Sea of Tranquility is a reasonably visually attractive game. The game offers nothing that’s particularly unique of engaging in terms of bonus features and the House Edge, while not notably bad, is still significantly higher than many other far better slots games. Sea of Tranquility would not be a game we would suggest going out of your way to find.
