Cosmic Monstronauts Demo

Dash Across the Cosmos With Adorable Monsters

In the Cosmic Monstronauts slot, MGA Games welcomes you aboard a violet spaceship where charming little monsters are blasting off into space. The game features an inventive layout set against a starlit backdrop portraying a galaxy filled with meteors and stars. Inside the ship, you’ll encounter cute cartoon-style monsters and Halloween pumpkins, adding a spooky twist to the action. The rapid-fire soundtrack brings an extra level of immersion to the overall gameplay.

Regarding the game’s cast, the low-paying icons are the A–J playing card royals, while four monsters (blue, purple bats, green, and orange) serve as the high-paying symbols. In addition, the special icons in the Cosmic Monstronauts online slot include wilds, scatters, and purple moons.

Boosters Reserved for the Boldest Astronauts

You’ll sense the richness of the cosmos while playing the Cosmic Monstronauts slot online thanks to these in-game boosters:

The wild symbol fills in for any missing icons in a winning line, except for the moon and scatter symbols, to complete the winning combination.

When three scatter (spaceship) symbols land, you are granted 5 free spins. Extra free spins can be unlocked whenever three or more scatters appear on the reels. During this feature, the 3 central reels spin together as a single oversized symbol.

The re-spin bonus game triggers when 6 or more moon symbols appear on the main grid, or when the moon symbol lands on the giant reel during free spins. The feature begins with 3 re-spins. The regular reels are swapped out for special reels that contain only moon symbols, other symbols, and blanks. Moon symbols remain locked in place while the other positions re-spin, potentially adding more moons, which reset the re-spin counter to 3 and also stay fixed. The bonus ends when no additional moons land during the re-spins. All prizes linked to each moon are then paid out, and these may also include jackpot rewards. The Mini, Major, and Mega jackpots pay 30x, 100x, and 1000x the bet, respectively.
