Invading Vegas Revenge on Mars Slot Review
Las Vegas is burning purple under an alien sky, and this time the invasion is running in reverse – there’s a green Earth hanging up in the corner as a reminder of where the payback is headed. Invading Vegas Revenge on Mars is the rare sequel that fixes what was wrong rather than adding to what wasn’t: the same walking cowboy the series has always run on, now backed by multipliers that finally give him something worth walking towards.
Play’n GO has sent its invaders back to the Strip for a third run. It plays on a 5×4 grid with 20 paylines, 96.2% RTP and mid volatility. Fans of the original and its Christmas follow-up will know the bones, and Cash Vandal covers similar neon city ground elsewhere in the catalogue.
The Strip and the Reels
Wins pay left to right across the 20 fixed paylines, with all line wins added together at the end of a round and the highest combination alone counting on each line. Wins from free spins and scatters are added to payline wins on top. The Space Cowboy is the wild and substitutes for everything except the scatter. When five of him line up, that’s the richest line in the game.
- Wild (Space Cowboy): 30x the total bet for five, 10x for four, 5x for three
Those wild values are multiples of the total bet rather than the line bet, which makes the Space Cowboy more valuable than a first glance at the paytable suggests. Beyond the regular paying symbols, four special symbols do the interesting work, and each has a single job:
- Wild (Space Cowboy) – substitutes for all symbols except scatters
- Walking Wild (Armed Space Cowboy) – sticky, walks across the reels during re-spins and free spins
- Scatter (space car) – pays in any direction, three of them trigger the free spins
- Mystery Symbol (space cube) – can flip into wilds or paying symbols before a spin resolves
Stacked high-paying symbols land on the last two reels in the base game, which is where the biggest normal wins come from. A full stack of aliens, cowboys or bigfoot-style characters filling the right side of the board can turn a quiet spin into something worth watching. All symbols can appear on all reels, in the main game and in both features alike.
Scatter wins sit outside the payline system entirely: the space car pays in any direction and doesn’t need to start on the left-most reel. That matters when you’re waiting on the bonus, because a scatter landing on reel five counts exactly as much as one on reel one.
The Walking Wild and Re-Spins
The Walking Wild is the series’ signature mechanic and it works the same way here. Land a full stack of any symbol on reel one and a full stack of any symbol, wilds included, on reel two, and an Armed Space Cowboy appears on the middle reel with a re-spin attached.
He’s sticky. Every re-spin moves him one reel across, and he keeps walking until he reaches the first or last reel. As the reels spin, the Walking Wild either turns into a wild or a normal paying symbol, and every symbol he reveals will be of the same kind. That trail of matched symbols is where the feature pays.
Two restrictions keep it honest. Scatters can’t land while a Walking Wild is active, so the feature can’t chain directly into free spins. And the wild never drops a Mystery Symbol onto the reel it’s moving towards, which stops the two systems stacking on top of each other by accident.
Mystery Symbols and Multipliers
The space cube is the new ingredient, and it’s the one that separates this game from its ancestors. Before every spin, Mystery Symbols on the board have a chance of flipping into wilds, and those wilds can arrive carrying a multiplier.
- x2 multiplier
- x3 multiplier
- x5 multiplier
- x10 multiplier
When more than one multiplier wild sits on the same winline, the multipliers are added together first and the total is then applied to the line win. Two x5 wilds on a winning line pay that line at x10. Mystery Symbols can also reveal as the most common paying symbol already on the board, which is the quieter outcome but still builds lines.
Free Spins on Mars
Three scatters anywhere on the reels start the round, and the terms are straightforward:
- 12 free spins on trigger
- 12 additional spins for every retrigger, via three scatters landing at once
- 120 free spins maximum across the round
- Same bet and same number of paylines as the triggering spin
- Stacked high-paying symbols move to the first two reels
That last line is the structural change. Stacks sit on the first two reels during free spins rather than the last two, so the big symbols land where wins start instead of where they finish. The Walking Wild stays sticky and keeps walking through the round too, so wins can build from the left and connect through the middle at once.
The stack migration is more than cosmetic. Because paylines pay left to right, a high-paying stack on reels one and two is live on every line that starts there, and any wild or multiplier landing to its right finishes combinations the base game can’t set up.
Our Honest Verdict
Overall Rating: 7.3/10
This is a game of waiting, punctuated by moments that justify the wait. You spin, you watch a stack build, and every so often a cowboy picks himself up and starts crossing the board while the aliens watch from the storefronts. That slow-build rhythm is the reason to choose it: the payback story plays out on the reels, not just behind them.
Its strength is that the features finally talk to each other. The walking wild used to carry this series alone and it showed; with multiplier wilds able to land in his path and the free spins repositioning the stacks, a round can now snowball instead of just ticking over. Its weakness is the pace between those moments – the base game can go long stretches delivering nothing but small change, and there’s no published ceiling to chase.
It suits players who enjoy a build and don’t need a five-figure promise to keep spinning. Anyone after brutal variance or constant action will find the Strip too calm. For the rest, this is the best the invaders have ever been.
