Today, we’re gathered here to explore the best alien slots available at US online casinos. Mind you, some of the most popular extraterrestrial slots aren’t available for US-based gamblers. However, there’s still a fine array of space-themed slot machines you can try out right now.

We focused our search on the biggest US casinos like Ducky Luck, SuperSlots, Wild Casino, Las Atlantis, and similar sites.

So, with that out of our way, let’s hop right into the top 5 list:

Top 5 Alien Slots

Without wasting any more of your precious time, here are brief overviews of the five best alien slots you can play right now:

• Alien Fruits from BGaming
• Deep Space Conquest from Urgent Games
• Project Space from Dragon Gaming
• Ally Aliens from Begames
• Alien Wins from RealTime Gaming

Alien Fruits

BGaming’s Alien Fruits might just be the best extraterrestrial slot available at US casinos.  Some of its key strengths include a wacky alien-themed atmosphere, amusing gameplay, the notorious Buy Bonus feature, and all the standard features we’ve come to expect from modern slots.

The list includes scatters that trigger free spins and random multipliers during free spins which can significantly increase the total win.

According to BGaming’s official Alien Fruits page, the volatility is high, and maximum win is a whopping €180,000. The game is available at BetOnline, alongside several other alien slots featured on this page.

Deep Space Conquest

Deep Space Conquest is a relatively new slot developed by Urgent Games. It has 20 paylines, plays in the classic 5×3 grid and has bonus spins triggered by 3 or more scatter symbols. Wilds are present as well. Not only do they substitute most other symbols but also have massive returns.

Deep Space Conquest has old-school Halo vibes, so sci-fi enthusiasts are bound to appreciate it. The overall atmosphere depicts perfectly deep space voyages and, let’s face it, that’s what you’ve all come here for. Deep Space Conquest is available at SuperSlots, so we recommend you check that site out and register for an account to give Deep Space Conquest a proper go.

Project Space

Next up we have Dragon Gaming’s Project Space. This isn’t exactly an alien slot, but a vibrant space exploration title that’ll captivate you with its unique gameplay elements, smooth animations, and great atmosphere.

Project Space offers a decent gameplay experience, but the RTP is bound to shock you. According to our research, Project Space has just 94.00% RTP, making it the worst game (RTP-wise) on our list. But, if you’re still interested in a thrilling deep space adventure, you can test Project Space at Vegas Aces. There are several other space-themed games on the platform well-worth checking out.

Ally Aliens

Made by Begames, Ally Aliens isn’t a common sight at US casinos. However, we thoroughly analyzed Red Dog Casino’s library of alien slots and found this hidden gem. On paper, it looks like a good game, with the 95.78% RTP, it’s slightly above market average.

The game is still relatively fresh too. More precisely, it was launched back in early 2023. It was an immediate hit among sci-fi and space lovers, though it still hasn’t found its way into the mainstream. Gameplay-wise, Ally Aliens can provide hours and hours of entertainment. The fancy graphics and quality soundtrack make for a good visual experience too. If you’d like to test it out, head on over to Red Dog Casino.

Alien Wins

Last but not least, we have Alien Wins by RTG. It’s a brand-new slot released in May 2024. The theme is pretty straightforward – wacky aliens, tons of respins, wilds, and other standard features of modern slots. You can even use the Cosmic Spins feature to get either 1 or 2 guaranteed wilds in the next spin. Keep in mind that 2 guaranteed wilds will cost you an arm and a leg.

If you’re ready to get the ball rolling with Alien Wins, we recommend you hop onto OnlineCasinoGames and take it for a spin.

How to Choose the Right Alien Slot

But, how to choose the right alien slot these days? For starters, make sure you’re only exploring online casinos that accept US residents. If you’re not sure, check out our guide for finding the best US online casinos as it’s bound to help you make the right choice.

We have a few more pieces of advice we’d like to share. So, grab yourself a hot beverage and enjoy the following:

Focus on the RTP values

RTP stands for return to player. It comes in the form of percentage which tells us how much the slot pays out (on average) for every $100 wagered. So, for example, if an online slot has 96% RTP, it means it will (on average) return $96 for every $100 wagered. Obviously, if you’re interested in maximizing your long-term profitability, you should only play slots with high RTP values (96% and above).

Keep Tabs on the Volatility

Let’s explain volatility real fast and help you learn its importance. In the world of online slots, volatility usually comes in three tiers: low, medium, and high.

If a slot has low volatility, it means the winning rate is quite frequent, but (most) win amounts are usually low.  If a slot has high volatility, it means you won’t win nearly as often, but once you do win the amounts will usually be high.

There’s no golden rule of thumb here. Low volatility is not better or worse than medium or high. It’s a matter of personal preference. However, in our experience, games with higher RTP percentages typically have higher volatility too.

Explore the Unique Features

It’s no secret that modern slots have all sorts of unique features. Some are branded, like Megaways, some have become a golden standard, like bonus spins via scatters, while other simply allow players to buy the bonus spins right away (the infamous Bonus Buy features).

It’s on you to decide which of these features you’d like to experience. If your first criteria is an alien theme, then we recommend you explore the five aforementioned slots, compare their unique features and figure out which seem like the most fun.

Choose the Ideal Casino to Play at

Last but not least, it’s on you to choose the ideal casino to play at. As you had the chance to see above, each of our featured games can be played at a reputable US casino. But, if you’d like a more sophisticated approach, we recommend you take the matter into your own hands.

How to do that? It’s simple – pick a few casinos that seem like the best options, then check out our reviews to figure out which is a best fit for your needs.

Alien Slots Are Out of This World…

There you have it ladies and gents, those are the top 5 alien slots we could find. The US market doesn’t have some of the most popular titles like Reactoonz and Invaders from the Planet Moolah. However, the likes of Galaxy Invaders and Alien Invaders make for a fine set of alternatives.

So, what are you waiting for? Pick the best extraterrestrial slots from our list, join the casino that features them and enjoy the gameplay!
