Once you do this the total number of free spins that you’ve won will be assigned along with a multiplier bonus. This second screen bonus game activates once you land the Mystery Ship symbol anywhere on the reels and you’ll then have to put your shooting skills to the test as you are tasked with firing a cannon (simply by using your mouse) to down a ship that appears on screen – before it wipes you out. There is also the Space Invaders logo which is instantly recognisable, a bunker and the lowest valued of all – Ace to Jack playing card symbols which have been designed in a space style. The main symbol to watch out for is the Wild Invader which has the ability to substitute to make a winning combination for all but the special symbols which are the Mystery Ship Scatter and the Bonus Cannon – more on these and their features later. While it may appear to be outdated and lacking the 3D graphics we have become used to, preference will probably come down to which era you were born in – with those of you who enjoyed the Space Invaders machine in pubs likely to be enthralled by the gameplay and the younger generation amongst you likely to be left underwhelmed. In true retro style, all of the symbols that feature in Fremantle’s Space Invaders slot machine are pixelated and hark back to the good old days of 2D arcade games. Coin values range from 1p to £5 and with between 1 and 5 coins allowed to be bet each payline this means you can play the Space Invaders slot in real money mode from 40p up to £200 per stake. The stakes are very generous as you get to select the number of paylines you’d like to activate with 5, 10, 15, 20, 25, 30, 35, and 40 all available, and as we always recommend players on how to play online slots, the maximum of 40 should be chosen – which will cost you more but provide you with an increased chance of winning. This slot version by Fremantle is of course based on the worldwide hit arcade game which was developed by Taito and first released in 1978 with the task being to defeat waves of aliens with a laser cannon to accumulate the highest score possible – straightforward but very addictive! Stakes Outta Space It is unlike your typical 5-reeled slot machine as it sees you battle against the aliens on screen with original sounds from the arcade game ringing out as you do so. It’s time for a shootout in space against those pesky alien invaders who are intent on taking over – but rather than a high score listing as an achievement the Space Invaders slot machine sees you earn hard cash for your services to mankind!
