The Alien Robot game can be found at Net Entertainment casinos. Net Entertainment do make the house edge information of their slots games available and this can be found in the help files of the game (usually accessed by pressing the ‘?’ button at the bottom left of the game window). Net Entertainment games appear to only have one setting.
Both Come On! and Unibet list the house edge as 3.4% when playing 243 lines and 3.7% when playing less.
Alien Robots – as the name might suggest – is themed on robots build by aliens.
This game is a 5 reel game that doesn’t use traditional paylines. Instead any three or more matching symbols on adjacent reels starting from the left side of the reels constitutes a win. This is equivalent to 243 normal paylines.
Alien Robots has only one bonus feature. When you hit three or more of the ‘Alien Spaceship’ scatter symbols anywhere on the reels, you are awarded a number of complimentary spins based on the number of Alien Spaceship symbols that turn up. During the complimentary spins if a wild symbol turns up, it expands to cover the whole reel and then the reels are re-spun while the wild symbol reel is held in place.
With a boring bonus feature, a weak theme Alien Robots could easily have found itself at the very bottom of the list. The low house edge this games offers does remedy this somewhat.
