Invading Vegas: Revenge on Mars Slot RTP, Details and Wager Limits

The Invading Vegas: Revenge on Mars slot game by Play’n GO uses a 5-reel, 3-row, and 20-payline game engine. That’s one of the most popular formats when it comes to online slot games. Create winning combinations by landing 3, 4, or 5 matching symbols or wilds from left to right in a payline, starting from the leftmost reel.

Bet levels here start at 10p but can get as high as £50 per spin in the demo. Use the + and – tabs below the reels to adjust your stake size. In some territories, you can up the pace with turbo mode or set up to 100 autoplay spins. Neither of these options is available at UK slot sites, though.

The Invading Vegas: Revenge on Mars RTP is 96.2%, which is the default number for a Play’N Go slot. There are also versions with lower values, including 94.2%, 91.2%, 87.2% and even 84.2%. Because of this, search for the best Invading Vegas: Revenge on Mars casinos, which offer the highest player return rates. The volatility here is in the medium range.

The Invading Vegas: Revenge on Mars max win is 2,500x. That’s an improvement on the 1,000x top prize in the original Invading Vegas game, but it’s still a long way behind the best online slots.

Invading Vegas: Revenge on Mars Theme—More Vegas Than Mars

invading-vegas-revenge-on-mars-slot-base-game

You might imagine that a slot with Revenge on Mars in its name would be set on the red planet itself when you fire up the game at your favourite UK online casino. Unless we’re in some strange parallel universe where there’s a Martian equivalent of Vegas, it looks like we’re in Sin City once again, albeit after the little green men have visited. Actually, maybe the aliens have transported Vegas lock, stock, and barrel to their home planet?

Either way, some familiar Vegas landmarks form the backdrop to the reels. On those reels, you will see 4 lower-value casino chip symbols and 5 higher-value alien characters. Top of the bill is the alien Elvis, who pays 6.4x if you land 5 in a line. Better still is the Space Cowboy that works as a wild. He substitutes for all the standard symbols and also delivers a 30x payout if you land 5 in a line. The Flying Car is the scatter, but also look out for mystery symbols.

When it comes to sound and visuals, there are few better developers of new slots than Play’N GO. The cartoon caricature-style imagery here is nicely done. It’s bright, bold, and works well for the not-too-serious theme.

The soundtrack hints at the classic UFO movies of the 50s mixed with a classic Vegas big band orchestra. It all comes together very nicely.

Here’s what the paytable offers:

Invading Vegas: Revenge on Mars Mobile Slot

invading-vegas-revenge-on-mars-mobile-slot

You can play Invading Vegas: Revenge on Mars at a large number of mobile casino sites. The colourful design and relatively straightforward gameplay make it a good fit for mobile play.

I found that both landscape and portrait modes worked just fine when playing the smartphone and tablet versions. In my opinion, there’s no great advantage to playing this alien adventure on a big screen as opposed to a smaller device.

Invading Vegas: Revenge on Mars Bonus Features

The feature action here revolves around walking wilds, mystery symbols with multipliers, and a free spins bonus round. To master it all, check out the demo version if you can. If you don’t enjoy it, there are loads of free casino slots to try at online-slot.co.uk.

Walking Wild Respins and Mystery Symbols

This feature triggers when you land a stacked symbol on reels 1, 4, or 5, but you don’t land a winning combination. A stacked wild is added to the middle reel. It then moves one position left or right on each re-spin. As it goes, it leaves between 3 and 12 mystery symbols until it reaches the first or last reel.

Each mystery symbol will reveal a standard symbol or a wild. If it’s a wild, it can come with a 2x, 3x, 4x, 5x, or 10x multiplier attached. Land more than one multiplier in the same winning combo, and their values are added together for a bigger payout boost. You can’t land scatters during this feature, nor can it be re-triggered.

Free Spins

invading-vegas-revenge-on-mars-slot-free-spins

Land 3 scatter symbols anywhere on the reels on the same spin, and you’ll receive 12 free spins. In the base game, stacked high-value character symbols can only land on reels 4 and 5. During the free spins, they can land on the first 2 reels, too, which improves your chances of landing the Walking Wild Re-spins. Re-triggers are also possible, with up to a theoretical maximum of 120 free spins.

Invading Vegas: Revenge on Mars Verdict: Not Exactly out of This World

2.7/5
Based on our expert’s review. Reviewed by
Invading Vegas: Revenge on Mars Slot

The cartoon visuals are nicely done, and there are some decent extra features here. However, the low max win in the Invading Vegas: Revenge on Mars slot game is quite a disappointment.

Pros
  • Free spins
  • Walking wilds
  • Some decent multiplier action
Cons
  • The 2,500x max win is rather low
  • Not enough excitement to set this entry apart from its predecessor

The formula in the previous Invading Vegas slots (walking wilds, free spins, outlandish soundtrack, and visuals) is present in Revenge on Mars as well. There’s an odd tweak here and there, and the walking wilds, mystery symbols, and multipliers can combine to deliver some decent action. It’s all perfectly fine—it’s just not that exciting.

Design-wise, it’s the usual top marks for Play’n GO. They always deliver when it comes to the sound and visuals of their slots.

A shame that the gameplay and payout figures don’t quite match up, though. The 2,500x max win is an upgrade on the original Invading Vegas slot but doesn’t really get the pulse racing.

If you enjoyed the other slots in this series, you’ll find plenty to like in Invading Vegas: Revenge on Mars. It’s all okay, but not exactly out of this world.

There’s more madcap action featuring Martians in Las Vegas in the original Invading Vegas slot from Play’n GO, so feel free to give it a spin.

If you prefer a simpler slot layout, try 10000 X Gold from 4ThePlayer, and you might get a 7,500x max win.
