Playing Astronaut slot is an exciting and slightly different experience compared to traditional online slots. The mobile slot features a 1x1 grid flanked by a 20-step progressive multiplier meter on both sides. Instead of traditional paylines, your goal is to climb the paytable by landing Green Crystals.

The game accepts bets ranging from €0.10 to a maximum of €4 per spin. Simply press the Spin button and hope to land a Green or Golden Crystal for a win. If luck is on your side, you'll be presented with the following options:

Continue: Gamble the next round using all the winnings accumulated so far.

Take Half: Deposit half of your winnings and continue playing with the remaining balance.

Collect: Collect all your winnings and end the current round.

For a more automated experience, you can activate the Auto feature and enjoy a series of preselected continuous spins. If you prefer a faster pace, the Quickspin option is available to speed up the Astronaut slot game rounds. Additionally, you can access the game information pages through the Help and Pays buttons to learn more about the game's features.

Note: The mentioned betting limits and options may vary depending on the specific online casino where you play Astronaut slot.

In the Astronaut online slot game, there are three main symbols: the Green Crystal, Red Crystal, and Golden Shield. Unlike traditional slots, you don't need to form winning combinations with these symbols to receive rewards. Instead, your goal is to collect Green Crystals and activate the Golden Shield for a chance at higher payouts. For more detailed information, please refer to the game's help page.

Green Crystal

Each Green Crystal you collect allows you to progress one step up the ladder. At each level, you have the option to Collect, Take Half, or Continue, as explained in the "How to Play" section. The number of Green Crystals you accumulate determines your chances of encountering the Red Crystal.

Payouts range from 1.1x at level 1 to an impressive 18,000x at level 20.

Red Crystal

If the Red Crystal appears on the reels and there is no active Golden Shield, the current game round ends. You will lose any stacked wins that haven't been cashed out and restart from the bottom of the paytable.

Golden Shield

When the Golden Shield symbol lands, it activates a protective shield that guards against the Red Crystal. If the Red Crystal breaks the shield, it increases the prize on the ladder. Additionally, automatic spins are triggered after Green Crystals land.

To unlock advanced multipliers ranging from 1.1x to a massive 48,000x your stake, try to hit the Red Crystal after the Golden Shield activates.

Now that you're familiar with the Crystals, let's explore the game's features in the following segment of our Astronaut slot review.

The Astronaut slot offers several exciting in-game bonuses, including Prize Ladder Levels, a Gamble Wheel, and a Jackpot Feature.

Prize Ladder Levels

The ladder prizes consist of stake multipliers, starting from level 1 to level 20, displayed in default or advanced multipliers. Some ladder prizes are calculated to two decimal places if the current stake would result in three or more decimal places.

Gamble Wheel

If you collect a win that exceeds €0.10, the "Gamble" button becomes active, allowing you to increase your payout. By using the Plus or Minus buttons, you can adjust the potential win on the ladder, which recalculates the wheel's probabilities.

If the Gamble Wheel pointer lands on the Red segment, you lose and return to the base game. However, landing on the Green section boosts your win to the highlighted prize you previously selected.

Astronaut Jackpot Feature

The Astronaut slot offers progressive jackpots that can be triggered through special features or by landing three or more jackpot symbols on the screen. Stakes exceeding €2 on games with progressive jackpots contribute to the jackpot tiers. The available categories include:

Hourly Drop: Starts at €50.

Daily Drop: Begins with a value of €2,000.

The Big Drop: Currently has a seed value of €175,735.43, with the next minimum starting value at €200,877.86.
