Invading Vegas Revenge on Mars: Slot Overview

In late 2022, Earth found itself under siege by shady alien invaders eager to get their little green hands on one of the planet’s top gambling hotspots. Or wipe it off the map entirely. That was the story behind Play’n GO’s online slot Invading Vegas. Not satisfied with a single raid, the nasty extraterrestrials came back for round two in the seasonal follow-up Invading Vegas Las Christmas. But enough is enough. Humanity isn’t taking another kick in the crotch and has launched a retaliation mission of its own, called Invading Vegas Revenge on Mars.

Oddly, in Invading Vegas Revenge on Mars, Mars looks suspiciously like Las Vegas on Earth—just dustier, with a strangely tinted sky. And the folks hanging around, seemingly deciding what to bet their hard-earned Mars dollars on, are definitely not human. The main character is, though, and on behalf of the human race he’s blasting off to dish out some alien payback. This is a revenge story, after all. And imagine the bonanza that would surge through the military-industrial complex if aliens really did invade—assuming we survived it. Think of all the new hardware the army would have to create to keep this fragile blue rock firmly in humanity’s hands.

Invading Vegas Revenge on Mars is a medium volatile slot played on a 5-reel grid featuring 3 rows and 20 paylines. It comes in multiple RTP configurations, with the highest set at 96.2%, and accepts wagers from 10 c to $/€50 per base game spin.

Four casino ships covered in alien markings act as the low-pay symbols, while 5 strange character icons make up the high pays. Five-of-a-kind wins on the low pays return 0.8 times the bet, while 5 matching high pays pay between 1.6 to 6.4 times the bet. Wilds substitute for all paying symbols and pay 30x for 5 OAK.

Invading Vegas Revenge on Mars: Slot Features

Invading Vegas Revenge on Mars includes a Space Cowboy wild symbol, an Armed Space Cowboy walking wild, a space car scatter, and a space cube mystery symbol. Wilds and walking wilds substitute for any symbol except the scatter to help form winning combinations. These symbols connect to the respins and free spins mechanics.

Walking Wild

A walking wild can be activated on the middle reel with respins when a full stack of matching symbols land (including wilds) on the two leftmost reels or the two rightmost reels, but no win is formed. The walking wild then moves one reel per respin until it reaches the leftmost or rightmost reel. During the respins, it randomly places 3 to 12 mystery symbols. Walking wilds never drop mystery symbols on the reel they are moving toward. Each mystery symbol reveals as either a wild or a regular pay symbol. All regular pay symbols revealed will be the same type, and the symbols that appear most often have a higher chance of being selected by mystery symbols. Before revealing, mystery symbols also have a chance to become wild, and those wilds may carry a multiplier of x2 to x10, applying the shown value to the win. If more than one multiplier lands in the same winline, their values are added together before being applied.

If the walking wild is triggered by the first two reels, it travels to the right; if it is triggered by the last two reels, it travels to the left. An extra respin is awarded when the walking wild reaches the outermost reel. Scatters cannot land while a walking wild is active, and walking wild respins cannot be retriggered.

Free Spins

Hitting 3 scatter symbols on the reels awards 12 free spins. The free spins feature is retriggered by landing 3 scatters, adding +12 spins each time, up to 120 in total. In the base game, stacked high-paying symbols are restricted to the two rightmost reels. In free spins, however, they may also land on the two leftmost reels as well

Invading Vegas Revenge on Mars: Slot Verdict

The mechanics may be tweaked, but much of Invading Vegas Revenge on Mars feels familiar. As with the earlier titles, one of the key aims is getting walking wilds to invade the reels, with mystery symbols scattered across the grid. The notable change is that walking wilds can now head left or right, depending on where the two stacks of identical symbols land. Previously, the walking motion ran left to right in the base game only, and it wasn’t until free spins started that the wild stack reversed direction. In Invading Vegas Revenge on Mars, two-way movement is baked in as one of the fresh additions. Possibly even better is that the stacked wild always appears on the middle reel when two outer reels show stacked identical symbols. Before, stacked reels only triggered a respin on the middle reel, which might or might not produce a stacked wild. Here, it feels more fun and less reliant on luck.

As with the last two invasion entries, Invading Vegas Revenge on Mars isn’t exactly overflowing with massive payouts. A top win of 2,500 times the bet doesn’t do much to elevate its appeal. The highlights are the sharp presentation and the pleasing way the reel area flashes with lively animations. Mystery symbol drops working alongside the walking wild is a strong point, especially when multipliers appear. Still, like the previous games, Invading Vegas Revenge on Mars doesn’t really get the adrenaline pumping. Then again, someone must be feeling it—this is the third Invading Vegas release, and they’ve all followed a fairly similar formula. As before, if the earlier invasions either got your pulse racing (or left you cold), there’s a good chance Invading Vegas Revenge on Mars will deliver the same effect.
