InBet Games have designed Martians Attack in spectacular detail, from the metal outbuilding reels to the graphics of the landscape behind the reels. Thanks to the way the reels are designed, it’s as if you are virtually in the middle of a crop fields somewhere – the type of crop field that attracts aliens – it’s rather eerie stuff. The 5 reels are surrounded in metal and each reel offers three symbols of which can offer; card values from 9 through to A, various sci-fi guns, a UFO, alien, abduction scene and metal bots.
The control panel as always offers options to adjust your bet and lines, initiate auto spin, spin and help on how to play. Make sure your volume is up because the sounds and effects that play out whilst you spin the reels are cosmic and very thrilling.
The UFO is one scary looking symbol, but it can add a frightfully good cash prize to your bankroll. High rollers staking 900 coins per spin will expect 5 of a kind of the UFO symbol to award the 900,000-coin jackpot. High value symbols come in the form of the alien with 450,000 coins and the alien abduction with 150,000 coins. Medium value symbols are the large laser gun with 75,000 coins, BBQ-looking bot with 80,000 coins and the small gun with 40,000 coins. Remaining symbols will award between 10,000 and 25,000 coins for a win line full of matching symbols.
Wild is the UFO – he will fly onto the reels and replace other symbols (except for scatter) to help form wins where they might have been missed. When a wild is used as part of a payline, the value of that win will be doubled. Scatters are the alien symbol – 2 anywhere in view awards a multiplier whilst 3 or more triggers free spins. When you have been awarded with free spins, you will be gifted 15 free spins with a 3x multiplier. Free games can be re-triggered when 3 or more aliens fall into view. Gamble feature put you against a virtual dealer. Gamble any value base game win on a turn of a card – red or black will decide whether you win double your money or lose everything.
Fancy being abducted by aliens? Well, now’s you chance. Martians Attack slot machine is a fun-filled, highly animated and thrilling slot that’s packed with basic yet rewarding features. Of all the Inbet Games slots on offer, this is by far the best in our opinion, thanks to the bulging jackpot offered and triple-value free spins. Big wins can be accumulated via free spins – thanks to the 3x multiplier, but we found getting our hands on these even harder than encountering aliens.
When we tested the Martians Attack slot, we were playing for what seemed an eternity before triggering free spins, but thankfully, there were plenty of base game wins to keep us hunting on for our freebies. We are totally impressed with the graphic and animations, although a little on the comical side of things, it’s fun and very chilling. If you love to play fast and furiously, you can click to spin the reels and then again to stop them – but this eats into your credit far quicker than allowing those reels to spin out on their own.
