The growing popularity of online casino slots has seen many new themes and features added. With science fiction being such a key genre in popular culture right now, it's no surprise to see space-themed games being added, but what innovative features do they include to boost the gameplay?

Alien Fruits 2 Has Random Multipliers in Free Spins

The Alien Fruits slot by BGaming has proved to be so successful that it's turned into a franchise, with Alien Fruits 2 bringing the colorful space creatures back for another invasion attempt. The creators have gone for a light-hearted feel that is common in the slot world, with funny aliens and an amusing background, rather than an edgy sci-fi feel. It's not going to provide answers as to whether there's alien life out there, but it does offer fast and fun gameplay.

Alien Fruits 2 plays like a classic slot machine over six reels, with a traditional free spins round where ten spins give the best chance of big wins. However, it varies from the classic slot machines of the past in the way that it adds random multipliers of up to 100x to symbols during the free spins, opening up the possibility of bigger prizes.

Alien Digger Has Sticky Wins During Free Spins

The Alien Digger game by Onlyplay takes place on a rocky planet where mining appears to be the main activity. Symbols include mining tools like dynamite and helmets, with an alien worker acting as the game's wild symbol to complete winning lines where possible. This brings to mind movies like Prospect and Moon, which have space mining as key elements in their stories.

Despite the otherworldly setting, the gameplay will be instantly familiar to anyone who has played slot machines before. However, the free spins round is where we also see an interesting feature added to this game. This is because every win during the bonus feature sees the winning symbols stick to the reels for the remaining spins, which increases the chances of large wins.

The slot can be played on this Bitcoin casino Canada website using BTC or other cryptocurrencies. These payment methods allow sci-fi fans to play gambling games using the security and privacy of the blockchain, with deposits moving instantly from their wallet to the casino's wallet. Bitcoin has enjoyed a lot of popularity in the last few years, and gaming in this way is becoming increasingly attractive to players everywhere.

Space Horror Has a Bonus Game with Three Jackpots

Space Horror by Onlyplay promises a grittier type of space trip, and the symbols don't disappoint, with gruesome aliens mixed with spacecraft and a tough guy astronaut. This article looks at why space is the best setting for horror movies, with fans of the Alien series and Event Horizon sure to agree. There's no blood or gore in this slot, but the symbols do a great job of setting up the atmosphere.

The slot reaches its moment of maximum tension in the bonus game, which is triggered when bonus symbols land on the screen. During this special feature, three respins are awarded. Special symbols award cash prizes, while the Major, Minor, and Mini jackpots can also be won when these images land on the reels.

Fantasy Universe Creates Giant Symbols

KA Gaming is responsible for this three-reel slot, which has planets and asteroids among the most important symbols. The game looks similar to the earliest three-reel slot machines, which were simple mechanical affairs where players pulled a lever to find out if they had won anything.

However, this online slot adds modern technology by turning stacked symbols into giant symbols that cover the full reel. Since many of these images are colorful celestial bodies, it creates a fascinating look as the game progresses.

This summary of the history of slot machines shows how changing technology has been added over the years to create new ways of playing using the same basic gameplay that was invented in the 1890s. No wonder so many of today's slots have such unique features!

Stellar Spins Has Expanding Symbols

The Stellar Spins slot by Booming Games mixed classic casino symbols like playing cards with sci-fi images, creating an interesting look. The game uses a standard reel-spinning mechanism, but the free spins rounds include an expanding symbol that is chosen before the bonus section begins.

There are ten fixed paylines over the five reels, allowing wins to be built when three or more matching symbols land together. The reels hover over a planet, but it feels more like a traditional slot than others on the list, as there's no sign of spaceships or alien life out there in space.

With new movies like Mercy and Project Hail Mary (starring Ryan Gosling as a school teacher trying to save the world from alien microbes) due out in 2026, we can expect to see science fiction making a lot of What Innovative Features Are Used in Space-Themed Casino Slots?s in the near future.
