Astronaut RTP, Details & Wager Limits

Reels/Paylines: 1 reel + 1 payline

Stakes Range: 10p to £2

Max Win: 48,000 x stake per spin

RTP: 95.69%

Expect to be surprised when you load up the Astronaut slot, as this game gives you a unique layout with only 1 reel. In the middle of the screen you’ll find a floating crystal. With two columns of prize values to either side. The crystal spins, much like a reel, but the slot is a little unusual. To create a win, you simply need to land a green crystal. Do so, and you have the choice of:

  • Gambling your win and progressing to the next prize level
  • Banking half of your win and progressing to the next level
  • Collecting the win

We’ll talk more about how the prize levels work later in this review.

Astronaut is playable from as little as 20p up to £2 per spin. Whilst this seems like a small betting range, the mechanics of the game mean that everythin’s up for grabs after every win so it’s still suitable for more risky players.

Outside of the UK., Astronaut has an Auto Spin function which you can use to play between 20 and 100 spins without clicking. You can also set win and loss limits.

Astronaut has an RTP rate of 95.69%. This is generous for Red Tiger Gaming and about average for a lot of new slots too. The game, does, however also come complete with a high volatility and max wins of 48,000 x your stake. The only way to reach anything near these heights is to keep spinning and progressing to the next level.

As you can probably tell by now, Astronaut is a unique slot with an innovative design. Thematically it is, of course, based around space. The game hangs against a galaxy background, complete with stars, meteors, and nebulas.

The game layout seems to be set inside a spaceship. Presumably, as an Astronaut it is your job to collect the all-important space crystals, of which there are three. These don’t work like traditional slot symbols, though the Green crystal symbols are the ones to look out for. These help you to progress to bigger prizes.

There are no wilds in this game but the Gold shield acts like a bonus symbol. It protects you from losses. We’ll talk about this more in the next section of the review.

Astronaut mobile

astronaut-mobile-slot

As is to be expected from a Red Tiger Gaming slot, Astronaut comes with HTML5 technology. This makes it flawless on all devices, including desktop, mobile and tablet. The simple design means Astronaut looks great on the smaller screen too.

Astronaut Bonus Features

Astronaut comes with just 1 main bonus feature, the Golden Shield. That said, there’s other unique elements to unpack too, so let’s get started.

Golden Shield Feature

astronaut-mobile-slot

As mentioned earlier, you must land green crystals to progress through the game. Landing a red crystal takes you back to Level 1, unless you are protected by a Golden Shield.

If you land a Golden Shield, the game will spin automatically. This means you no longer can choose to bank or walk away. This is because you now have protection and cannot lose a prize.

This continues until a red crystal lands which breaks the shield. At this point, you do not lose your prize, but instead go into Advanced mode. Prizes in Advanced Mode are increased, but you no longer have protection.

Prize Levels Feature

Astronaut comes with two columns to the sides of the reel, each displaying prize level values. There are 20 prize levels in total and you can progress through the levels by collecting Green crystals.

Here’s what prizes are available at each level of the game, in both regular and Advanced Mode:

Level Regular Prize Advanced Prize
1 1.16 x bet 1.16 x bet
2 1.54 x bet 1.62 x bet
3 1.92 x bet 2.12 x bet
4 2.6 x bet 2.98 x bet
5 3.46 x bet 3.84 x bet
6 4.8 x bet 5.38 x bet
7 6.82 x bet 7.68 x bet
8 9.6 x bet 10.08 x bet
9 14.44 x bet 15.36 x bet
10 20.64 x bet 23.04 x bet
11 31.68 x bet 34.56 x bet
12 51.84 x bet 59.52 x bet
13 91 x bet 101 x bet
14 154 x bet 168 x bet
15 298 x bet 346 x bet
16 528 x bet 730 x bet
17 1,152 x bet 1,440 x bet
18 2,784 x bet 3,840 x bet
19 6,528 x bet 10,560 x bet
20 18,000 x bet 48,000 x bet

Note that some values might be rounded up to the second decimal place, if a result based on the current stake would yield a value with 3 or more decimal places.

Originality








Firstly, Astronaut is a good looking game and it definitely boasts unique features. Whilst slots purists may not even recognise this is as a slot game, we quite liked that it pushes for an innovative new take.
When it comes to gameplay, the most notable characteristic of the game is that it requires you to keep playing and progressing through levels for a chance to win those 48,000 x max wins. You can’t simply spin and land a supreme symbol combination to boost your bankroll.

The game will obviously appeal to a certain type of player. To have the courage to keep going for higher levels will take an awful lot of strength, or stupidity, depending on how you look at it. That said, with low max stakes, it’s as suitable for budget players as it is for high rollers.

With the Astronaut slot, we highly recommend giving our free demo game a spin before playing for real money. It won’t be to everyone’s tastes, but it could just be the thing you’re looking for.

Love the theme of the Astronaut slot but not keen on the gameplay? Try Cyberslot Megaclusters by Big Time Gaming instead. Still not completely tradtional, it offers a cluster pays mechanism, max wins of 23,960 x stake per spin, roaming wild multipliers and more.

Pros
  • 48,000 x max wins
  • Unique reel mechanism
  • Chance to bank wins
Cons
  • Volatile
  • Gameplay may not be for everyone
