The most exciting action on offer in this slot machine is provided courtesy of the special bonus round of free spins. That is because players will have the opportunity to win some out of this world prize money thanks to bonus multipliers worth up to x5. The average RTP of this slot machine is 96.40%.

The Edge of Space

The Final Frontier takes spinners somewhere that they have never been before – deep space. Join the crew of adventurous space explorers as they investigate some curious objects found floating around in the furthest reaches of outer space. Your spaceship-mates are a duck, a domesticated cat, and an imperial white lion. And what is this mysterious space debris, you wonder? Asteroids? Comets? Stardust? Nope, we’re talking about cosmic cherries, orbital oranges, inter-planetary plums and weightless watermelons.

Of course, serious astronomers and stargazers might not appreciate the slightly erroneous nature of this novelty space themed video slot. However, from a purely aesthetic point of view, this game is very attractive to a universal audience, with 3D reel icons set above a stunning deep space star-scape.

Astronomical Wins

What do these floating fruits have to tell us about the mysteries of the cosmos? Well, some questions are better left unanswered. What we can tell you is that the icons in this low variance slot machine will form winning combinations on a relatively regular basis, providing a range of line bet multipliers. Should three matching fruits line up from left to right on an active payline, then a 5x multiplier will be applied to the bet on that line while four matching fruits will go for 25x and five fruits will award 100x.

The more valuable symbols in the game are depicted by a cosmic crystal, a magical interstellar flower, a daring duck and a cosmonaut cat. The biggest win by far in this slot machine is awarded when players find five matching lion characters, weighing in at a decent 2,500x. Unfortunately, however, the prize winning limit in this online video slot by Merkur is limited by a maximum line bet of just 1.00 credit. Spinners can enjoy this game with all 10 paylines in play for a maximum total bet of 10 coins while there is also an option to play with just 7, 5, 3 or 1 paylines. The minimum possible bet with all paylines activated is 0.10 credits.

If players aren’t completely happy with the size of the prize, then they can take matters into their own hands by risking their wins in one of two side gamble games. There is a straightforward 50/50 gamble available in which players have the guess the colour of a playing card while the ladder gamble game offers some more complex risks.

Hyper-Space Bonus

Exploring the mysteries of deep space is all good and well but it is no fun without any bonus boosts to keep you entertained. Let’s face it, there’s not a lot to do while you are floating around in a tin can! Luckily, The Final Frontier offers a number of special bonus gameplay elements, from wild wins to free spins.

The first of the bonus features is provided by the captain of the spaceship – the wild lion character. This wild symbol will effectively complete wins on active paylines by substituting for any ordinarily paying symbol on the reels. The only icon which the wild lion won’t replace is the atomic reaction scatter symbol, simply because this special icon does not need to line up on a payline to trigger the game’s main bonus feature of 10 free spins. So, should three of these scatters appear, the free games will begin with a x1 multiplier and every time that an additional scatter falls on the reels, another 5 free spins will be added to the tally. Not only that, but an additional scatter will boost the free spin multiplier by x1.

Out of This World?

The Final Frontier is a Merkur Gaming slot machine that will transport punters far far away to the other side of the universe from the comfort of their own homes. The game is stunningly designed with some homage paid to the retro slot machine genre with a number of fruit machine icons. The most exciting aspect of the game, however, is the potentially rewarding round of free spins with bonus multipliers.
