Master the Spaceman’s Unique Gameplay 

Spaceman is a crash game, kickstarting your space quest with a 1x multiplier and increasing it gradually as long as the astronaut flies. If the spaceman crashes and burns, you’d leave the casino empty-handed. However, if you pull the brakes on time, you’ll win a multiplier active at that precise moment.

Astronaut (Red Tiger)

Red Tiger Gaming is one of the most sought-after providers in our trusted online casino in Singapore and other top-ranked casinos across the world. Their relatively new slot release from April 2023 has caused a commotion among space-theme game fans, taking them on a memorable Green Crystal chase through the cosmos. Astronaut is one of the most compelling online slots, set on a visually alluring spaceship. 

The deep-colored background shows a flickering nebula behind the simple grid consisting of one reel and one row. And although this highly volatile slot has a 95.69% RTP, you could still win big time with a small stake. It allows you to collect a 48,000x maximum payout if your stars smile upon this journey. 

Astronaut’s Levels & Prizes

This unique space-themed slot has only two extra features – but still surpasses all expectations with its multiple levels. Its features include the Golden Shield and Advanced Level, with the first protecting you from Red Crystals, while the latter unlocks a new world of opportunities to cash in if the Golden Shield breaks. 

Advanced Level has 20 sub-levels, each multiplying your winnings from 1.1x to a maximum of 48,000x the bet. This growing prize ladder qualifies the slot as a “crash game,” dodging the well-known concept of features, and adding a fresh layer of excitement due to the uncertainty of the outcome.
