Captain Xenos: Earth Adventure Slot Free Play

Theme of The Game

Captain Xenos: Earth Adventure’s story revolves around an alien space pirate, which crash landed on our planet. Play n GO crafted a cartoon-style design for it, with the right images used for the alien crew that accompanies the pirate.


While the first five low paying symbols give us the Royals, standard options but not very interesting, for the five premium icons they’re using images of the alien pirates. The top one is Captain Xeno, while the others have images of Chief Mechanic Filla, Boon, Drox, and Atom.


A slot machine developer that has managed to reach the top of the industry, Play n GO has launched hundreds of games in the last two decades. You can’t go wrong playing at casinos which have their games, since they launch a new one pretty much each week.

How to Play

Captain Xenos: Earth Adventure Slot Free Play

How To Play It

There is a long list of bet values that you can select from, and they’re available at the bottom. Scroll to the left and right, and you get from the minimum bet of $0.20, to a maximum one of $100.


You’re going to start off with 5×4 reels, where there are 1024 ways to win active. Up to 32,768 ways can become available. Getting paid through regular combinations is possible when 3 or more symbols of the same type land on consecutive reels, starting from the leftmost one.

Special Features

A blue-colored neon light was used to create the W logo, a symbol which is your wild in this game. It’s available to be used as a substitute, but that’s not all. It also creates combinations with the other wilds, and pays up to 3x the stake on each line then.


Electric Shock is the name given to one of the random features. When it triggers, it will select one type of symbol, and will make it split into two. All symbols of that type will split, giving you more ways to win as a result. This can only happen for regular symbols.


Emergency Wilds is the other special feature, which you can trigger at random during paid spins. Up to 5 wilds are added to the reels, when it triggers.


Engine Recharge is the third modifier that could come, and it will give you 2 scatter symbols. This makes it much more likely to get access to the free spins, since you only need 1 more scatter to land naturally.


With a Red Power Source symbol landing 3+ times, scattered on the reels, you can gain access to the free spins. Depending on the number of scatters landing, you get 8 to 12 rounds in this mode. You collect scatters once inside, and you upgrade the feature, getting more spins. During these upgrades, you also give symbols the ability to split into up to 3 symbols, and then into 4. At this point, getting up to 32,768 ways to win becomes feasible.

Maximum Payouts

Up to 10,000x the stake may be paid by Captain Xenos: Earth Adventure, after just one round even, if it’s the luckiest one possible. You’d need to get the free spins going first, but it’s possible.


You’re looking at a slot machine with an RTP range, but the top value is 96.20%, so the high volatility isn’t as big of an issue as it might be otherwise.


Captain Xenos: Earth Adventure looks like fun, and it can be interesting to play as well. That’s if you discount its increased volatility, because risky slots are rarely fun to play for the majority.
