Invading Vegas: Revenge on Mars Slot Bonus Features

Play’n GO’s wild and wacky series returns, and this time round, it’s even stranger than ever. After two alien attacks on Vegas, it seems like humanity has decided to return the favour and strike Mars this time around. The thing is, Mars seems to be an alien version of our own human Vegas, complete with tacky-themed casinos in the middle of the desert and a cast of alien Nevada stereotypes.

Out in Mars’ version of the Vegas desert, you get a traditional grid made up of five reels and three rows which account for 20 paylines. To score a win, you’ll need to put together a minimum of three identical symbols on adjacent reels, starting from the leftmost reel. The more symbols you have in a winning combination, the better the payout you’ll receive.

At the bottom of the paytable, you get four low-paying symbols with differently coloured chips; variations include:

  • purple
  • blue
  • green
  • red

These tokens offer payouts ranging from a lowly 0.20x your stake to a high 0.80x your bet.

On the other hand, the upper parts of the pay table are taken up by Mars’ very own 5 denizens, including:

  • an elderly, purple alien lady
  • a blue bookie alien
  • a green showgirl alien
  • a cowboy alien
  • a red Elvis impersonator alien

It’s quite a handful of characters, with the Elvis impersonator alien serving as the highest-paying token of the lot, awarding you wins of up to 6.40x your bet for five identical symbols.

Play’n GO has also included some very helpful functions, including:

  • the option to toggle turbo mode on, which significantly increases the speed of each spin
  • an autoplay function with up to 100 consecutive rounds spinning automatically

That covers all of the video slot’s basics, but Invading Vegas Revenge on Mars builds on this with a variety of special features.

Wilds

Earth’s very own alien-murdering space ranger is the game’s wild symbol, stepping in for missing pay symbols on a potentially winning payline. Wilds can also combine with existing wins to deliver an even bigger payout.

 

Armed with an array of weapons and an equally fearsome moustache, the wild symbol’s ranger is the video slot’s highest-paying symbol, awarding 30x your stake for five identical symbols. But there’s more.

 

Wild symbols are tied to the respins function through the walking wilds feature. Whenever you land two stacked reels filled with identical symbols without a win, you activate the respins bonus. This spawns a stacked wild on the middle reel, moving to the left or right of the grid on each consecutive respin until it finally walks off the reels.

 

As it moves around, it can leave up to 12 mystery symbols on the grid. These mystery symbols reveal wild symbols with win multipliers of up to 10x your stake. Any wins you make while these wilds are active, take advantage of the combined values of these wild multipliers.

Scatter Symbol

To access the game’s free spins bonus, you must land three scatter symbols, awarding 12 free spins. Scatter symbols don’t have a payout value, but they also land during the free spins bonus, allowing you to add more bonus rounds to your tally.

Free Spins

During the bonus rounds, the gameplay remains mostly the same, except that walking wilds are active now and can randomly land on any spin, bringing a host of wild multiplier-yielding mystery symbols with them. You can also continue adding more bonus rounds, with a cap of 120 maximum free spins available.

 

There are no bonus buy or ante bet options, so you must rely on the scatter symbols landing to access the bonus rounds.

RTP & Volatility of Invading Vegas Revenge on Mars Slot

The Invading Vegas Revenge on Mars math model is quite even, with volatility clocked to a medium setting, together with a range of RTP values including 96.20%, 94.20%, 91.20%, 87.20% and 84.20%. I’d stick to the highest, 96.20% version for the best experience possible.

But while those numbers paint a pretty picture, the issue here is the maximum win, which caps at 2,500x. It’s a relatively low maximum win and not one that can be easily reached either, resulting in a game that feels largely unrewarding even when you manage to trigger several of its special features.

Invading Vegas Revenge on Mars Slot on Mobile

I tested out Invading Vegas Revenge on Mars using my Android phone and was unfortunately disappointed with the results. I played it through a Chrome browser, and the game simply remains identical to the desktop version while adding touchscreen controls.

It’s still playable, especially in portrait mode, but I would have appreciated having larger buttons and a more curated portrait mode that would make it easier to play on smaller screens. As such, I recommend playing this on a desktop or a large-screen mobile device like a tablet instead.

Other than that, the game maintains all the same features, visuals and win potential, so you get a seamless experience across all platforms. You can also play on iOS devices through modern browsers like Safari, Opera and Firefox.

  • The game has a medium level of volatility, but I would still err on the side of caution, especially after Anton’s experience with the game. There are loads of fantastic features on offer and these can land in both the base game and free spins, so you’ll never feel all too bored when waiting for the special feature to drop.
  • I recommend sticking to a low bet level, something that can buy you hundreds of base game spins and, in doing so, increase your chances of activating the bonus rounds. It took Anton well over 200 base game spins to get his first free spins bonus, so you will need to be quite patient with the online slot despite its medium volatility setting.
  • ✅ There are also no bonus buy or ante bet options available, so you will need to wait for these features to trigger organically through scatter symbols, with no alternatives to fast-track you into the bonus.
  • ✅ As always, remember that video slots like Invading Vegas Revenge on Mars run using random number generators, which means the outcome of each round is randomised and cannot be influenced.
  • ✅ There are also no strategies or tips that can guarantee you can win more money. Stir clear of any false myths and tricks to win fast and instead focus on efficiently managing your bankroll for the best experience possible. Always play for fun and never for profit.

The first two entries in the Invading Vegas series may not have been slam-dunks, but they showed a lot of potential promise that could be improved upon in later sequels. But after playing Invading Vegas Return to Mars, those hopes don’t seem all too bright.

 

The feature set remains largely the same, with a minor change in the walking wilds, which can now move both left and right. It’s certainly a welcome change, but I was looking for a more significant upgrade to the overall setup, as the original offerings weren’t exactly a winning formula.

 

But perhaps the biggest disappointment here is the 2,500x maximum win cap, which makes it very difficult to score meaningful rewards. The math model needed to get an upgrade here to make the game more lucrative, but as it stands, this counter-invasion keeps looking more and more like a bad idea.

 

You’d think that its saving grace would be in the visuals department, but you’d be wrong. While the video slot has high-quality designs, the animations aren’t all that impressive. What’s worse, though, is the fact that this theme simply copies and pastes the original’s backdrop and symbols, creating alien versions of the original. On the one hand, the ironic twist here can be just what Play’n Go was going for, but it still ends up feeling lazy and cheap.

 

Despite its big promises, Invading Vegas Revenge on Mars drops the ball with few meaningful improvements on the original game.
