Invading Vegas Revenge on Mars

A 5x3 layout with 20 fixed paylines carries Invading Vegas Revenge on Mars, Play'n GO's follow-up that flips its alien-invasion series around: this time the humans launch the assault, jetting to a dusty, red-skied Mars built to look suspiciously like a relocated Las Vegas strip. Locals wandering the strip are unmistakably alien, while the player's own space-cowboy protagonist heads off-world purely to settle the score from the earlier invasion games.

Four alien-branded casino chips make up the low-value symbols, sitting beneath five stranger character faces as the premiums; five of the top character symbols pay between 1.6x and 6.4x the bet, against 0.8x for the chips. A Space Cowboy wild substitutes for every symbol except the scatter and completes a full line for 30x.

The bonus engine runs on an Armed Space Cowboy walking wild: landing a full stack of one matching symbol, wilds included, across either the two leftmost or two rightmost reels without a win triggers a respin on the centre reel, and the resulting walking wild then marches toward whichever side it wasn't triggered from — right if it started on the left, left if it started on the right — gaining an extra respin once it reaches the far reel. Along the way it drops three to twelve space-cube mystery symbols, skewed toward whichever regular symbol already appears most on the grid, and any of those cubes can instead reveal a wild carrying a multiplier between x2 and x10; stack more than one multiplier wild into a single win and their values are added together. Scatters sit out while a walking wild is running, and the feature cannot retrigger itself.

Three space-car scatters award 12 free spins, with a further +12 for every additional three-scatter hit, up to 120 in total. Stacked high-paying symbols are confined to the two rightmost reels during the base game, but spread to the two leftmost reels as well once the free spins are running.

Revenge on Mars carries a medium volatility rating of 5 out of 10 and hits somewhere on the reels roughly once every 5.76 spins, with wagers of 0.10 to 50 per round. RTP peaks at 96.2%, stepping down through several lower configurations to 84.2%, and the maximum prize on offer is capped at 2,500x the bet — the same ceiling set by its Vegas-set predecessor despite the change of scenery.
