Invaders From The Planet Moolah Slot Video - HIGH LIMIT $1000 Session - LONGPLAY!
The Invaders From The Planet Moolah slot machine by WMS is a classic!
It even has two sequels, although the second version never caught on like the original but the latest version, "The Return" is doing much better! The base game employs "Cascading Reels" where symbols fall down and fill the reels after which any winning combinations are paid, and then something extra happens: the symbols in all paytable-defined combinations disappear and new symbols cascade down to take their place, and any new winning combinations formed are now paid. This process continues until no new paytable-defined combinations are formed and it's not too uncommon to get multiple reels of cows for that Big Win.
The "Invasion Bonus" is triggered one of two ways: randomly after a any spin which does not trigger the bonus itself or after a spin which has at least 4 cascades. 4 cascades will award 7 free games, 5 will award 10, 6 will award 15, 7 will award 25, and 8 or more will award 50 free games! The bonus, an alternate set of reels is used which I believe has some more cows, which are the wild symbols in the game, although I'm not 100% sure on that. Cows only appear on reels 2 thru 5. Retriggers are possible in the bonus and I've seen this one used as a base game in the "Big Event" games WMS created, although they don't seem too popular these days. All in all, it's a fun game, especially if you can fill reels 2 thru 4 with cows, Enjoy!
