"Sea of Tranquility" is one of the slots produced by "WMS - Williams Interactive" with more positive comments on forums and websites related to online gambling, not only for its simple design and relaxing sound effects, but because it could be considered a highly generous slot, and not precisely for its paytable, but for some kind of extra chance offered to the player either to form combinations as a result of the expansion of its wild symbol or to trigger the free round, explaining better, this game has 5 x 3 reels, but in addition WMS has added a cell at the top and bottom of the reels that operate virtually as two additional rows only for cases where either wild or scatters symbols appear on that places and if they are useful to the player, for example, each time a wild appears in one of these cells, the wild expands around the respective reel just as it would if it had appeared on any of the 3 regular rows, this one is the only slot that converts our "almost" into reality, it does the same when scatters should be eligible to trigger a round of free spins. During the free round we also have a better chance to form best combinations with the 3 main symbols of the game, which indeed, they have a size of 3 frames high, and during the free spins round these 3 symbols work as substitute each other; personally during the round of free spins I have managed to have all the reels fully covered with these symbols and fragments of them and extended wilds, which is equivalent to having the entire grid of 5 x 3 reels completely covered with the same symbol, and in this case it would be the symbol with the best prices in the game, it is clear that the payout for this kind of achievement is not astronomical, but the other reality is that situations like this are highly likely to happen in this slot, and lower prices on paytable are necessary for the game to remain economically viable for casinos.

I know and play this game since some time ago and I liked it from the first moment, it is apt to earn some dollars not to make a fortune, however it has good application in the process of meeting wagering requirements. Nice game.

What can I say about the video slot Sea of Tranquility from WMS. The name suggests an ocean of peace and that’s exactly what I got first time playing this game. I lost 30 euros min betting on 30 cents per spin in no time. Many appalling dead spins, a session you wouldn’t even wish to your worst enemies.

However, I felt like my job on this game wasn’t done. Fast forward, two weeks later I decided to play this game again. Sea of Tranquility offers 5-reels and 3-rows like many other slots, and also has 30 paylines. The thing that attracted me to playing this game was the “Close Enough” Area of the slot, which is the reel above and under the main reel set.

We all hate it when a wild or scatter symbol drops just above or under the slot. Well, Sea of Tranquility solved that problem by enabling you to profit even if the wild or bonus symbol appears on the reel above or under the main reel set.

In addition, the game also has expanding wilds. So it’s possible to get a whole screen of wilds with a bit of luck. Anyway, like I said, two weeks later I was out for my sweet revenge. I started with a budget of 60 euros and betted 60 cents per spin, and managed many great hits thanks to expanding wilds and the Lady symbol. Within 10 minutes of playing I was able to double my bankroll.

I wanted to experience the free spins as well though. You need 2, 3, 4 or 5 bonus symbols appearing on adjacent reels from left to right to trigger the feature which awards respectively 7, 10, 20 and 50 free spins.

I never got more than two but that doesn’t matter. My feature was excellent since the wilds kept coming in like candy and so did the money. In total I won more than 180 euros from those 7 free spins combined. Not bad right?

Well there is more, shortly after I triggered the feature again and won 100x bet size (60 euros) and that’s when I decided to quit this game and replace it by another. Overall an excellent game if it’s in the mood to pay, and I also like the concept of “Close Enough”.

I don’t think I ever seen that anywhere else before, apart from the “Nudge” functionality on some slots like Microgaming’s Untamed series.


Can swallow up a balance real fast if not in the mood to give. Scatters have to appear on adjacent reels to trigger free spins.

“Sea of Tranquility” from WMS slot is a surprisingly good quality slot. I chose this slot completely at random and I was extremely surprised when after the first 20 spins I won over 20 Euro with an amazing ease. I did not expect that at every spin of these first 20 spins I will have each time a win of 1-10 Euros (playing with a bet of only 30 cents). I was under the impression that this is just the first slot I play where I could not have lost ever. And yet... After another 100 spins I had come to where I started. What means human greed... I wanted much, much more and it was like the slot was telling me: play, keep playing, and then it tricked me.

The slot is still very good, even because it makes the player wanting more and then it tricks him. The atmosphere is pleasant, charming even if this story did not told me much. However its graphics are exceptional with symbols extended on a whole reel and Wilds that extend the same. You are really surprised when you find out how easy it is to have two simultaneous extended Wilds and combinations of “4 of a kind”.

And more is offered to you in Free Spins: all the major symbols are equivalent and thus easily from 7-10 Free Spins you get 5-15 Euros every time. However I have remained with a misunderstanding: it is said that the “Moon” is scatter and from 2 Scatters up the Free Spins are triggered. After the first two series of Free Spins in the first 20 spins, although I frequently had 2-3 Scatters on the reels I have not entered into the Free Spins. And I do not know what to say about this.

I said that I stopped playing when I returned to the starting amount after only about 150 spins. It is less than I usually play at a good slot, but the quality of the game is perfect from the first spins and there is no need to play much.


I stayed with one unpleasant impression: the payouts for the minor symbols are rather small and sometimes a win is only about as the bet paid. Perhaps many slots are much weaker in this respect but here where you win so much so easily, these payouts may be seen a negative aspect.
