The Sea of Tranquillity, as everyone knows, is an ocean on the moon, surrounded by high peaks. This celestial body does form an important part of this game by the leading games developer, Williams Interactive, and features in many of the symbols used.
The Sea of Tranquillity slot is a five reel game, with thirty pay lines. The background is an unknown universe, shaded in light and dark purple, with planets and shooting stars orbiting in the distance. The main symbols include a Jar of Fireflies, an Owl and a gold Amulet, a Space ship flying through the air, a night-cap, and a beautiful Girl. The Wild is a green and gold Shooting Star, and as such can substitute any other symbol in the game to complete a winning combination, apart from the Scatter symbol. The Scatter is a sleeping New Moon, and will be the trigger for one of the bonus rounds. The symbols with the lower value are the traditional playing cards, from Ten through to the Ace.
Above and below each reel is a limited view of another row. If a Wild or Scatter symbol drops one reel position and appears there it will be active and count as being in play. If it is a Wild symbol, it will expand to fill the entire reel, the same way it would in a normal view. This is the Close Enough Feature.
The Free Spins bonus round is triggered by the appearance of two or more Scatter symbols anywhere on the reels, from left to right. If you land two Scatters you will win seven free spins and a multiplier of twice your initial stake. Three Scatters will get you ten free spins and five times your original wager. Four Scatter symbols appearing will give you twenty free spins and a multiplier of ten times your first bet, while five Scatter symbols will award you with a huge fifty free spins together with a multiplier of twenty five times your first bet, on any wins you may make during this bonus round. Also, during this feature, the Girl, the Spaceship and the Owl can all substitute for each other, and this can offer some extra opportunities for jackpots and online roulette Australia playing online casino games.
The free spins round can be reactivated by landing two or more Scatters while playing this round. Because the free spins are triggered by the Scatter symbols, the symbols do not have to be on an active pay line. You can use just one pay line if you wish, but of course the wins will be much bigger if you use all the pay lines. In the Sea of Tranquillity slot you can put all pay lines into live play. and can then play from one to five coins on each activated pay line. There is an Auto Hold option if you wish to use this to let the game play itself. Control buttons can be easily seen and are all situated together at the bottom of the screen.
Another great feature the Sea of Tranquillity slot game offers players is the Bonus Guarantee feature. If you use all the possible pay lines in game play, when the Bonus game is triggered you can win at least five times your initial stake.
