Prepare to venture into outer space and take to the streets of an otherworldly Las Vegas in Invading Vegas Revenge on Mars. You’ll need to keep your wits about you around here; there are some truly hideous-looking aliens to be found on these reels, but if you can land three scatter symbols, you’ll at least bag yourself 12 free games to play with. You can land a further 12 free games if you land another three scatters during the free games round too. You in? Game details: Play’N Go Slots, free games, scatter symbol, wild symbol, aliens, Mars, Venus, Jupiter, space.
