Unusual Options Mark Sea of Tranquillity Slot
With five reels only displaying three windows each, hanging against an imaginary cluster of planets and moons, Sea of Tranquillity slot at first glance appears a fairly bland, old-fashioned casino game. However, developer WMS Gaming is known for the varied and innovative extras in their slot games, and Sea of Tranquillity is no exception.
Those who give the game a go will notice the bonus touches immediately. Multi-window symbols, high-value symbols that can mix-match with each other during bonus play, expanding Wilds, and WMS’s unique Close Enough feature are just some of the special extras that make Sea of Tranquillity a slot less ordinary.
A Mixed Moon Myth Theme
Humanity’s age-old fascination with the moon is the theme permeating Sea of Tranquillity, and the slot’s iconography draws from the legends and tales that have grown up around our celestial neighbour. The high-value symbols are an owl landing under a full moon, a moon goddess, and an airborne sailing ship, flying to the moon, all of which are three windows tall. During bonus rounds, the owl, goddess and ship can form mixed combinations for prizes, so they win big when they line up exactly, filling adjacent reels and potentially, all 30 paylines.
Lower-value symbols include a gold moon pendant, a jar of fireflies and a nightcap of the type worn by Wee Willie Winkie. The least profitable icons are the standard Poker symbols 10-A, adorned with the usual WMS gems, coronets and coats of arms.
30 Fixed Paylines, but Adjustable Bets
Sea of Tranquillity uses 30 fixed paylines, meaning the player must bet them all, every spin. However, bets per line can be adjusted from 0.01 in whatever currency’s in use, up to 5.00, so the bet per spin ranges from 0.30 to 150.00.
Wild Expands and Can Be Close Enough
The Sea of Tranquillity Wild is a green shooting star, and whenever it crops up it will expand to fill the entire reel. Above and below each reel, part of the next window up or down is visible. This enables the Close Enough feature. If a Wild is showing in one of these windows, it’s close enough; the Wild will expand and stand-in for any other symbols, apart from the bonus, to complete winning combos.
Detailed WMS Icons as Usual
Like all WMS slots, Sea of Tranquillity symbols and effects are beautifully drawn and animated, from the ghostly sailing ship to the fireflies. The Scatter Bonus is a stylised Man in the Moon drawn as a crescent moon with a face, snoozing peacefully. The Scatter also qualifies for the Close Enough feature, so two or more Scatters anywhere on the reels or in the Close Enough windows trigger free spins and multipliers.
The game awards 7 free spins and 2X the total bet for two Scatters, 10 and 5X for three, 20 and 10X for four, and five Scatters win 50 free spins and 25X the total bet. Free spins can be retriggered by more Scatters during bonus play; along with the mixed high-value symbol combinations possible, and the expanding Wild with Close Enough options, this makes every bonus round a potential big winner.
