Are you a truth-seeker searching to play demo slots for free? Scan the skies for signs of alien life in these top slots below.

With reports of strange things in our skies ramping up over recent years, the topic of UFOs and aliens has never been more in the limelight. But sci-fi movies, books and games have long flirted with the idea of extraterrestrial beings coming down to planet Earth, whether that’s as invaders, diplomats, or infiltrators. Whether this topic is entirely fictitious or there is more truth to it than some might believe, it’s safe to say that many of us love to think about the possibility of life from other planets visiting ours.

Here at Play’n GO, we’ve curated some of our best alien-themed slots to satisfy your imagination, so get ready to be beamed up and take them for a spin for free!

Invading Vegas

One of the greatest fears of those that ponder the existence of others beyond our home are that they won’t come in peace. Unfortunately for Sin City, that’s exactly the case! Spacecraft have appeared, and they’re Invading Vegas!

These little green men have seen the bright lights and heard the tales of thrills and vice and have decided to make it their stomping ground for a night of revelry, chaos, and hopefully some big wins! With features including Stacked Wilds and Free Spins, this is surely going to be a night to remember for these interplanetary invaders.

Invading Vegas: Las Christmas (coming soon)

After their last successful venture to Earth, these aliens have chosen to come back and spend the holidays here as well. But this time there’s a problem. They’ve accidentally collided with Saint Nick’s sleigh and have all but ruined Christmas! Feeling guilty for putting Santa out of action this year, they’ve agreed to help save Xmas instead of staging another invasion.

Invading Vegas: Las Christmas is filled with features just like Santa’s sleigh. Walking Wilds, Free Spins, and the Lock On Re-spin mode will help you and your new alien pals make this Christmas out of this world.

Gargantoonz (coming soon)

The infamous Dr Toonz has finally done it. After bioengineering many impressive creatures while hidden away in his secret laboratory, he has finally created a one-eyed Gargantoon, the first of its kind. Dr Toonz is hoping to introduce this new alien creature into the Reactoonz society and generate unimaginable riches! But, of course, more testing must be done first.

Fill the Experiment Charger with 20 winning symbols and prepare for one of three to begin. With the Gamma Ray, Black Hole, or Supernova experiments fully charged, the grid will begin changing, increasing win potential with their chaotic and exciting results, including Sticky Wilds and Moving Wilds being added to the grid. So, grab your safety goggles and labcoat and get ready to help Dr Toonz with his most important experiments yet!

Reactoonz

In his early days, Dr Toonz created the super-charged Reactoonz. With some scientific manipulation, Dr Toonz took the alien Energoonz species and helped them to evolve. This symbiotic relationship allowed the Energoonz to become much more powerful, and in turn made Dr Toonz very wealthy!
