The original Planet Moolah let you win up to 50 free games (which could be retriggered), but Invaders Return can go up to 200, which can be doubled under the right circumstances. But then, it adds additional features.įirst off, the top free games available has increased.

First off, the game increases from 25 to 30 lines, so you get a bit more on the line hits. It follows the slot sequel formula of bumping up the bets 40% (although only from 25 to 35 credit increments, still quite affordable for the time) but adds a lot of new components. While sequels like Invaders! Planet Moolah and Planet Wombat followed, Invaders Return from the Planet Moolah builds directly off the original in terms of animation, format and sound.

The success of the cascading reels game Invaders of the Planet Moolah, which recently has seen a remake, has been enduring, with the original game out about 20 years at this point.
