Invaders from the Planet Moolah Review
If your love for all things Roswell-related translates into the entertainment that you seek, Invaders from the Planet Moolah is the slot machine game for you.
Packed full of fun graphics, interesting space sounds, and plenty of opportunities to bonus, it offers excitement with every spin of the reel.
Close encounters of the third kind await you with this game by WMS.There’s nothing quite like watching dairy cows being abducted by alien cow pilots! An intergalactic good time awaits you with the Invaders from the Planet Moolah bonus round.
Take a chance on spinning its reels and you may have an out-of-body experience when you win big.
Take Me to Your Leader
You’ve probably seen enough alien abduction movies to know how it works. Aliens love livestock and the slot game Invaders from the Planet Moolah is no different. It features cow pilots in each of its five flying saucers.
The symbols on the reels are all farm-related and include Grandpa, Grandma, Man, Cowgirl, Dogs, Chicken, Truck, Trailer, Mailbox, Outhouse, Barn, and Milk.
Resembling any small farm in the Midwest, the game tells the tale of what it’s like to live in a secluded part of the country prone to alien invasions.
As the spaceships abduct livestock, you can’t help but chuckle at the surprising moo that is let out with each cow that is taken from its home.
Even the name of the game is comedic as moolah typically refers to cash money but also identifies the name of the planet that the cow invaders come from.
Minimum and Maximum Bets
The MIN bet is $0.25. The MAX bet is $125.00. There are 5 reels and 25 paylines in Invaders from the Planet Moolah. The maximum payout is 3750 coins a spin, while the RTP is 92.97%.
When wild symbols appear on reels 2-5, it makes all symbols wild.
The AutoSpin option is available and active until you click to deactivate it. That means that as long as there are credits on the machine, the reels will continue to spin until you stop them.
Invaders from the Planet Moolah Slot Machine Features
There are two main features that are activated in Invaders from the Planet Moolah slots. They are Cascading Reels Feature and the Invasion Feature which becomes active during the Cascading Reels Feature.
Each could lead to a bonus Feature which helps you earn additional cash with every free spin awarded.
Cascading Reels
The Cascading Reels Feature can be found in many slot machine games. When a combination of winning symbols is present on the reels, they disappear and are replaced with other symbols that combine together to create new winning combinations.
The five UFOs zap away the symbols revealing the new symbols. You need eight consecutive wins to launch the bonus feature which could help you rack up large sums of cash.
You also have the opportunity to be taken to the Invasion Feature where 7 free spins could help you bonus, too.
Invasion Feature
Get four wild cards in a row during the Cascading Reels Feature and you’ll be taken to the Invasion Feature where 7 free spins are rewarded.
If eight wins in a row is achieved, you’ll activate the free spin bonus feature where 50 free spins are yours for the taking.
Bonus Rounds
During the Cascading Reels Feature, you’ll also wind up with chances to bonus. With up to 50 free spins awarded, you can win a significant sum of money especially if any of the spins activated the Cascading Reels Feature and free spin bonus again.
Being able to bonus several times while the reels are spinning is one of the things that makes this basic slot machine game extraordinary.
If you play your wild cards right, you could have back-to-back free spins which steadily increase the amount of money that you win.
Out-of-This World Fun
Invaders from the Planet Moolah slot machine offers non-stop fun and excitement. From its illustrative graphics to its hilarious intergalactic sound effects, this game has a lot of entertainment value.
It offers a decent paytable, plenty of opportunities to bonus, and low minimum bets making it a game you can play for a while without suffering big losses.
With its multi-feature rounds and recurring bonuses, it’s easy to see why players return to this game for additional doses of hilarity and entertainment.
Introduction
Alien Attack Keno is a keno variant by Action Gaming. It features a bonus and another bonus within a bonus themed with a battle between cows and aliens. At the time of this writing, the game can be found at VideoPoker.com, where a Gold level membership is required to play that game. I imagine it will be seen on casino floors beginning in early 2021.
Rules
- The base game is the same as conventional keno, which I assume the reader is familiar with.
- The player may choose 3 to 10 spots for the base game.
- The player will choose two Bonus Spots from among the numbers he didn't already pick for the base game.
- The game will draw 20 random numbers, as in conventional keno.
- If less than two of the Bonus Spots are hit, then the game is scored as in conventional keno.
- If both Bonus Spots are hit, then the player will play the Pick-a-Prize Bonus.
In the Pick-a-Prize Bonus there is a grid of 19 icons, with the following distribution. Prizes are relative to the bet amount.
Pick-a-Prize Bonus Prizes
Prize Weight Probability 1 11 0.578947 2 1 0.052632 3 1 0.052632 5 1 0.052632 10 1 0.052632 15 1 0.052632 Alien Attack 3 0.157895 Total 19 1.000000 - If the player picks an Alien Attack, then he will play the Alien Attack bonus (a bonus within a bonus).
- In the Alien Attack bonus, the Bonus Spots the player should pick three numbers to mark with cows and three to mark with aliens. The player choose the numbers previously marked as Bonus Spots.
- The game shall pick 20 numbers, as in conventional keno.
- The player will always get paid on his base game picks in the Alien Attack bonus, as usual.
- If no cows or aliens are marked, then the free spin shall act like an initial spin.
- If the ball draw matches at least one alien and no cows, then the aliens will abduct one of the cows.
- If the ball draw matches at least one cow and no aliens, then the player will win a multiplier to be applied to the base game win. This multiplier is 2x for one cow hit, 3x for two cows hit, and 5x for three cows hit.
If the ball draw matches at least one cow and one alien, then what I will call a 'milk battle' will ensue. This is displayed as the cows hurling milk and cheese at the aliens. The number of shots fired by the cows will equal the product of the number of cows and number of aliens spots marked in the ball draw. Each shot fired shall award a random prize. The prize weightings depend on the number of cows remaining, as follows.
Milk Battle Prizes
Prize 1 or 2 Cows 3 Cows 1 13 5 2 3 4 3 1 4 5 1 5 10 1 1 20 1 1 Total 20 20 In addition, if the player has one or two cows, then with each shot fired there is a 60% chance at a cow rescue. The probability of a cow rescue is 12/13 if the Milk Battle prize was 1, otherwise it is 0. At most, one cow may be rescued per bonus game. Although the game presentation may show otherwise, the cow is not rescued until the end of the bonus game. In other words, the number of cows is taken as the total at the beginning of the bonus game.
- The bonus shall keep playing until the player has no cows left.

Space Cows Slot Machine
It should be noted that the makers of this game claim a return for the same pay table of 89.467%. The reason for the 0.056% difference I attribute to random variance in the simulation.
