The space-themed Astronaut slot machine by Red Tiger Gaming is one of the best online slots for anyone looking for an easy-to-play online game. Spin one reel position, and land different colored crystals to move up and down the prize ladder when you play Astronaut on mobile, tablet, or desktop.
Climb the Ladder
Wager 0.10 to 4.00 coins a spin and climb the 20-level ladder to win bigger prizes when you play Astronaut slot online. You’ll step up to the next level and win the corresponding prize each time you land a green crystal, while golden crystals cancel out the next red crystal.
