The last place you want to have stress when checking out a game is with the betting options, so players will be pleased to know that there’s not exactly much new to learn here. The action takes place over the standard five reel layout and the use of thirty win lines means that there’s plenty of flexibility without needing to lose track of the wins as they happen.

Sea of Tranquility by WMS

The outstanding feature of the game in normal play is the addition of the Close Enough engine, which is new functionality from WMS and allows players to benefit from enhanced symbols. This can lead to a variety of extra bonuses, such as expanding wilds to go with the already expanded regular symbols such as the ship, ensuring that this game is great if you like to win on every single win line at once. That’s not the only feature action as you can also enjoy free spins with noticeable regularity, with up to fifty on offer, although somewhere in the region of ten is more common, although we can’t complain with how often the round hits. The standout aspect of the bonus game is that the high paying symbols – those that come along in stacks as standard – will pay mixed, meaning that you can line up ships and owls, not to mention wilds, without missing out on any wins.

Sea of Tranquility is definitely a break from the norm and a welcome addition to the Williams Interactive slots selection here on the site. Try it yourself here on the page, or play for real cash whenever you’re ready at any of the featured WMS casinos at the top of the page.
