Aliens RTG Slots

No one would ever want to meet an alien. You never know whether they will prove to be friend or foe. But RTG has done some work to bring us some cool alien-themed slot games to play. Try the following titles and see whether they prove to bring the theme to life in an interesting way.


A quick title that tells us exactly what to expect from this game. It tells the story of an alien invasion, played out on a five-reel, all-pays screen. This is an older game, depicting robotic aliens and alien spaceships hovering over cities.

There is a resistance robot in red used as a substitute icon, replacing most other symbols in the game. Only the game logo cannot be substituted by that robot. Your wilds will only appear over the middle three reels. Find three scatters and you will progress to the Alien Invasion Bonus. There are 15 alien ships to choose from, most of which hide prizes. Find the COLLECT ALL message and you'll do just that before progressing to another round of ships. Avoid the COLLECT message though as that ends the round.

Outta This World

Will this slot game manage to live up to its title, we wonder? Outta This World Slots gives us a more cartoonish take on the idea of aliens in outer space. They look quite cute, standing on top of one of the planets that appears in this game. They can also appear as full-height symbols in this game. As you might guess, that means the alien is an expanding wild, so it turns out to be pretty handy to see it.

The five-reel slot offers 20 lines to bet on. While the expanding alien can show up on any of the three odd-numbered reels, the black hole icon - used as a scatter symbol - cannot be replaced by it. This is the only symbol that cannot be subbed by the alien, though.

Find a black hole on the second and fourth reels simultaneously and you can trigger the bonus. There are 10 planets shown on the screen, some of which have five free spins to offer and some of which hide multiplier prizes. Two aliens are also hiding behind the planets though, and you must avoid these if you can. Collect as many spins and multipliers as possible before you meet both the aliens. You then collect your prizes and play those spins.
