Let’s try to protect the farm from unexpected hostile visitors from outer space. Alien KO is an online slot game developed by Green Jade Games with an alien theme. This slot features cartoonish visual elements like colorful icons related to the theme, reel positions with stripes, a view of the farm in the background, and an animated alien in a spaceship next to the reels.
Alien KO comes equipped with 6 reels and has 50 paylines. It also has a paytable with eleven standard symbols – five playing card icons, three cows, a scarecrow, a young farmer, and an old farmer. You can also expect to find a green neon wild sign that acts as a wild icon and substitutes for all standard symbols when needed. Next, we have the loot box symbol. Wait to land three or more of them on adjacent horizontal reels to get cash reward or activate Free Spins. During free spins, players can land a sticky wild icon that counts as any standard symbol and stays in its place until the end of this round. Finally, don’t forget that this slot uses a special Knockout system (KO) – you can knock out symbols (make it disappear) and a new symbol will come to its place. There’s a KO meter that shows you how many and when do you have knockouts available.
