Outer Space Invaders Slot

Another incredible slot for Leander Games to add to their repertoire, Outerspace Invaders certainly packs a punch. With the chance to win between 5x and 5,000x the initial stake, this slot is profitable for all players, regardless of their budget. Complete with 5 reels, 3 rows and twenty five active pay lines, this slot has a lot to offer the player in terms of space for winning. With reels set against a post-alien world with smog and smoke all around, this slot is visually incredible.

The attention to detail is impressive, with a short introductory animation, giving the player time to fully embrace the striking design and graphics. The introduction explains that Robert, Rachel’s fiancé has been abducted by a green alien called Zerk, complete with a flying saucer, tentacles and ray guns. Shotgun in hand, Rachel is ready to fight back. If you listen closely to the background music, which players often ignore, you will hear the eerie cries of fear, mixed with the sounds of ray guns and alien-like sounds. All of these have been designed to give the player full immersion into the slot.

Bet Strategy and Symbols

With a bet range from 25p to £100, this slot has plenty to offer every player, with the chance of winning up to 5,000 times the stake. This slot has different symbols for the base game and the Free Spin Feature. In the base game, the higher value symbols include Rachel, Robert, Zerk, the General and the Soldier. These are well design in an almost-cartoon-like style. Lower value symbols are the royals: A, K, Q, J and 10. These are all neon coloured. During the Free Spins Game, there are four higher value symbols: a tentacle and ray gun, an alien mouth, a tentacle, and the face of Zerk. Lower value symbols include an alien spaceship, a ray gun, a old-fashioned telephone, a alien invasion newspaper and an old-fashioned radio. The wild in this slot is a red square with the words RACHEL GOES WILD printed across it.

These replace all symbols of the slot, except the Free Spin and Bonus symbols. When a wild appears, only on reels 2, 3 or 4, it will expand vertically and fill the whole reel. The Free Spins symbols is an orange square with the words FREE SPINS embossed against the slot. The Bonus symbol forms the shape of a radar, with the word BONUS imprinted on the front.

Bonus Features

The Free Spins Feature is a large part of the slot’s charm, showing Rachel fighting back against Zerk as he tries to steal her fiancé Robert.

The player is given 10 spins and must inflict 10 points of damage in order to defeat him. There are three special attach symbols, each showing Rachel with either a grenade, gun or bat and offering 3 steps, 2 steps or 1 step respectively on the free spins win multiplier bar. The bonus game in this slot is the Radar Shootout, which can be triggered when the player matches three or more of the bonus symbols on the reels. There is the potential of winning 1 of 18 different bonus prizes, where destroying spaceships on the radar helps to increase the multiplier, which you win one the game is finished.


With incredible graphics, a storyline to follow and the potential of winning up to 5,000 times the stake you play, this slot offers something for everyone. With a bonus game, bonus features and two sets of symbols, Leander Games have spare nothing in making the Outer Space Invaders Slot the best it possibly can be.
