Invaders from the Planet Moolah is the WMS slot where cows in flying saucers hover over a farm and zap the winning symbols off the reels. It has been a casino floor favorite for years. The demo on this page is the online version, published by Light & Wonder, with the same 5 reels and 25 paylines.
The game has no scatter symbol and no bonus symbol. Everything depends on cascading reels. Each win clears symbols and lets new ones fall in, and four or more wins in a row from a single spin earn free spins. The longer the chain, the more spins you get, up to 50.

How Invaders from the Planet Moolah Works
The reels are 5 columns by 3 rows with 25 paylines. A payline is a fixed path across the reels, and wins pay from left to right starting at reel 1. Bets on the online game run from 0.25 to 125 credits per spin. The symbols follow the farm and alien theme.
After any win, the saucers above the reels beam up the winning symbols. The symbols above drop down into the gaps and new ones fall in from the top. If that makes another win, it happens again. This is called a cascade, and one paid spin can produce a whole chain of them. The wild replaces regular symbols and is removed like any other winning symbol.
The RTP is 96%. RTP is the share of all bets a slot pays back over a very long time. Volatility, which describes how often and how big a game pays, is rated medium. The reels also carry a UFO jackpot symbol, and the largest win is listed as 750 times the bet.
Invaders from the Planet Moolah Bonus Features
Cascading Reels
Every winning combination is removed from the screen and replaced by symbols falling from above. All new wins are paid, and the process repeats until a drop produces no win. You pay for the first spin only.
Free Spins
Four cascading wins in a row from one spin award 7 free spins. Five in a row award 10, six award 15, seven award 25, and eight or more award 50. The free spins begin once the cascades stop.
Retriggers
Cascades keep working during the free spins. A chain of four or more wins inside the round awards more free spins from the same table, so the bonus can extend itself.
Wild Symbols
Wilds stand in for the regular paying symbols to complete a line. When a wild is part of a win it is beamed up with the rest of the line, which opens more space for new symbols to drop in.
More Invaders from the Planet Moolah Versions to Play Free
The three other Invaders games are newer takes on the same cows and saucers. Invaders Megaways uses the Megaways reel system, where the number of symbols on each reel changes every spin. Invaders Blitz plays on 6 reels and 4 rows with 4,096 ways to win. Invaders Takeover adds a random wild modifier and a free spins round that holds wilds above reels 2 to 5. None of them uses the original 25-line layout.
Good to Know Before You Play
- There is no scatter to watch for. A meter on screen counts your cascades, and the fourth one in a row is what starts the bonus.
- Three cascades in a row is a common near miss. It pays its line wins but no free spins.
- You cannot adjust anything to make cascades more likely. Every drop of new symbols is random, the same as a fresh spin.
- The 50-spin award needs eight wins in a row from a single spin, which is rare.
