Rules and Gameplay

In the innovative realm of Red Tiger’s Astronaut slot, players encounter a departure from traditional gameplay, engaging with a single reel that challenges conventional slot mechanisms. This game introduces a unique approach where players must land green or red crystals, or a golden shield, to navigate through the prize ladders. Starting bets range from 10 cents to $2 per round. The objective is clear: collect green crystals to ascend the prize ladder, dodge the red crystals to avoid ending the round, and utilize the golden shield for protection against losses, while also triggering advanced mode for enhanced rewards.

Bonus Features

Astronaut slot introduces distinctive bonus features aimed at enriching the gameplay experience:

  • Golden Shield: Acts as a barrier against the red crystal, offering players a safe passage until it’s encountered, thereafter enabling Advanced Mode with superior prizes.
  • Advanced Mode: Once triggered, players benefit from increased prize values, elevating the potential for significant wins.

These elements contribute to a strategic layer, where players must decide when to risk continuing their ascent for greater rewards or when to secure their current winnings.


The Astronaut slot game features a concise yet impactful array of symbols, each playing a critical role in the gameplay:

  • Green Crystal: Allows players to progress up the prize ladder, offering a chance to increase winnings.
  • Red Crystal: Ends the game round, with all winnings forfeited unless previously cashed out.
  • Golden Shield: Provides protection from the next red crystal and triggers Advanced Mode for enhanced rewards.

These symbols form the core of Astronaut’s gameplay, dictating the flow and strategy of each session.


Astronaut slot offers a compelling payout structure, with the potential for significant rewards. The maximum payout in the standard mode can reach up to 18,000x the bet, while the Advanced Mode dramatically increases this potential to 48,000x. The game’s high volatility ensures that while wins may be less frequent, they can be substantial when they occur.


Given the unique gameplay mechanics of Astronaut, the traditional concept of paylines is absent. Instead, the game focuses on ascending a prize ladder through strategic decisions made by landing specific symbols. This innovative approach provides a fresh perspective on slot gaming, where success is determined by climbing towards higher prizes rather than aligning symbols across predefined paylines.

Innovative gameplay with a single reel mechanism High volatility may not suit all players

Minimum and Maximum Bet

The Astronaut slot offers a flexible betting range to accommodate various player budgets. The minimum bet starts at just 10 cents, making it accessible for casual players. On the other end, the maximum bet is set at $2 per spin, which while modest, allows for control over spending while still offering the chance for substantial wins.

Game Jackpot

The jackpot in Astronaut can reach up to 48,000x the player’s bet, achievable in the game’s Advanced Mode. This high potential payout reflects the game’s high variance, indicating that wins may be less frequent but can be significant when they occur. The Return to Player (RTP) rate is set at 96%, which is around the industry standard for online slots, providing a fair balance between the casino’s edge and the player’s chance of winning over time.
