Invading Vegas Revenge on Mars
Invading Vegas Revenge on Mars Slot Review
Invading Vegas Revenge on Mars takes the popular Play’n GO alien invasion concept into a new setting, moving the action from Las Vegas to a strange Martian version of the famous casino city. This time, however, the story is reversed. Instead of aliens invading Earth, humanity sends a Space Cowboy to Mars to fight back against the extraterrestrial forces.
Invading Vegas Revenge on Mars continues the Invading Vegas series while introducing changes to the Walking Wild feature. The Wild can travel from either direction depending on where stacked symbols appear, giving the base game a different flow compared with its predecessors.
Theme and Design
Invading Vegas Revenge on Mars mixes the bright casino style of Las Vegas with a futuristic Martian setting. The game features dusty landscapes, alien characters, glowing lights, space vehicles, and casino-themed designs.
A human Space Cowboy travels to Mars on a revenge mission against the aliens. Colourful animations and science-fiction visuals give the game a fun space-themed identity while keeping the connection to the Invading Vegas series.

Four casino- and space-themed symbols form the lower-paying group, while five unusual alien characters provide the higher-value symbols. Five matching low-paying symbols can award 0.8x the bet, while five matching high-paying symbols can provide between 1.6x and 6.4x the bet.
The Space Cowboy Wild can substitute for regular paying symbols. Five Wild symbols on a payline can award up to 30x the bet, while special Wilds and Mystery Symbols can create additional opportunities during the game’s feature sequences.
