Invading Vegas Revenge on Mars (Play’n GO) – Review & Demo Play

Invading Vegas Revenge on Mars - Slot Overview

I’ve spent time with Invading Vegas Revenge on Mars, the third slice of Play’n GO’s alien saga, and it lands as a 5x3, 20-line video slot with medium volatility. Stakes run from 0.10 to 50, with a top RTP setting of 96.20% and lower models in the wild. The scene is Mars made Vegas, purple sky, Earth in the distance, and a Space Cowboy front and centre. The core loop is about Walking Wild Re-Spins, Mystery Symbols, and a 12-spin bonus round, with a max win of 2,500x the bet.

Invading Vegas Revenge on Mars Slot Information

Lines pay left to right on adjacent reels, with wins for three to five matching symbols. The studio keeps it tight with 5 reels, 3 rows, and up to 20 paylines, nothing fancy on the grid. The max RTP is 96.20%, though operators can pick 94.20%, 91.20%, 87.20%, or 84.20% versions. I kept my bets in the mid-range and felt the medium profile in action, with steady base play and feature spikes driven by stacked reels and the cowboy wild.

Low pays are casino chips with alien emblems in purple, blue, green, and red, paying 0.8x for five of a kind. Premiums are five showbiz-like characters, worth 1.6x to 6.4x for five. The Space Cowboy wild substitutes and pays 30x for five. Scatters come as a space vehicle, while space cube Mystery Symbols can turn into regular icons or wilds with multipliers. In the base game, stacked high-paying symbols only land on reels 4 and 5.

Walking Wild Re-Spin in Invading Vegas Revenge on Mars

Walking Wild Re-Spin triggers when the first two or last two reels are fully stacked with the same symbol and there’s no win. A full-stack Armed Space Cowboy lands on the middle reel, and the feature begins. If the stacks were on reels 1 and 2, the wild walks right; if on reels 4 and 5, it walks left. You get a respin for each step until it reaches the edge, with an extra respin granted when it hits the outermost reel.

During each respin, the walking wild drops 3 to 12 Mystery Symbols across random positions, never on the reel it’s moving towards. Those cubes flip to one regular pay symbol type across all cubes or turn into wilds. Scatters do not appear while this is active, and the sequence cannot retrigger. It’s a tidy change from earlier outings, as both-way walking now happens in the base, giving the setup a better rhythm.

Before they reveal, Mystery Symbols can become wilds with multipliers of x2, x3, x5, or x10. If more than one multiplier joins the same payline, they add together before applying to the win. Regular reveals favour symbols that are more visible on the reels, which helps build lines while the cowboy marches. I rate this tweak higher than the old middle-reel gamble; the guaranteed stacked wild in the centre feels less swingy.

Mystery Symbols in Invading Vegas Revenge on Mars

Mystery Symbols in Invading Vegas Revenge on Mars work hand in glove with the walking wild. The cubes either settle on a single regular symbol type or upgrade to wilds that can carry x2 to x10 multipliers. Because multipliers stack by addition when they hit the same line, small clusters can climb fast. Placement avoids the destination reel of the walker, so the board fills around the path. It’s a neat lever for building lines and multiplying them in one sweep.

Free Spins in Invading Vegas Revenge on Mars

Hit three scatters and you’re in for 12 free spins. The Walking Wild Re-Spin behaves the same as in the base. The real change is symbol placement: during free spins, high-paying symbols can land stacked on reels 1 and 2 as well as 4 and 5, making both-way walking setups more common. Retriggers are possible with another three scatters, adding 12 more spins each time, capped at 120 in total.

In practice I saw the round swing on stacks aligning to trigger the cowboy early, plus multipliers landing from cubes. Without those, it can feel flat. With them, the board lights up nicely, though the ceiling holds at 2,500x the bet, so it’s a measured hunt rather than a blowout chase. Medium volatility fits that picture: bursts come, but the game stays on an even keel between features.

Invading Vegas Revenge on Mars - Slot Verdict

Looks and motion are on point, with Mars-Vegas backdrops and swanky swing tying the set together, but the maths leans familiar. The headline tweak is the both-direction Walking Wild, plus the guaranteed middle-stack when two outer reels are stacked, which makes the feature less random. Mystery multipliers up to x10 add spark. The trade-off is capped headroom at 2,500x and mid-range tempo. I’ll spin it for the animations and tidy flow, not for life-changing hits.
