Alien Spinvasion may just be the closest you will ever come to a close encounter of the third kind. This 5-reel, 3-row and 1 to 50 variable paylines slot from Rival offers prizes of up to 250 coins on an active payline!
The theme for this slot is out of this world, with the background consisting of an image of burning gaseous clouds. The reels are transparent so you can see the planet earth from behind the symbols. There are six upper-paying regular symbols that include an asteroid, space saucer, planet earth, red phone, Alien and ray gun. There are six poker symbols that represent the lower-paying end. Included in the game is suitably themed music that plays even when the reels are idle. There are also several audio effects that are triggered when the reels are in play, a payline win has been formed or a feature unlocked.
Alien wild encounters
The aliens are wild and they are appearing anywhere on the spaces as sticky, triggering a free re-spin in the process. If any more aliens turn up during the free-spin, then it is extended for an additional free spin with the wild staying in place.
Army general free spins feature + drop icons and extra symbol
Against alien attackers, earth has its foremost army general to lead in her protection. When he appears on your screen, you automatically win 11 free spins. When triggered, the symbols become what the game calls "drop icons". This is another way of saying "cascading" where any winning paylines explode creating gaps which are filled by symbols cascading from above. During the free spins only, an extra symbol is added in the form of a rocket for a chance to really blast off!
War of the worlds
Alien Spinvasion slot has a theoretical return to player (RTP) of 95.98% on bets that start at €0.01 and top out at €125. The payline wins are calculated by taking the coin win that you will find in the paytable and multiplying it by the coin value per payline. While you can vary the number of paylines from 1 to 50, we suggest you play with all paylines for the best chance of winning. The top payline win is 250 coins, followed by 125, 100, 75, 50 or lower. This slot offers a blend of great graphics and audio effects which solidify the space-invaders theme and prepare you for a war of the worlds.
