Play Invaders Attack from the Planet Moolah for Free

When they hit on a theme, US slot developer WMS love to run with it. WMS has constantly revisited its popular land-based and online slots to tweak features, improve bonuses, or increase jackpots. You can play for real money on all WMS's games, of course, but players always want something fresh and new.

The highlights of the original Invaders from the Planet Moolah video slot were the free spins bonus and the cascading reels. Invaders Return from the Planet Moolah improved on the original gameplay too. But what does this fresh land-based slot have that compares?

Well, the free Invaders Attack from the Planet Moolah slot is still played on five reels, and many of the symbols haven't been changed. The setting is still a sleepy Midwest farm that has been taken over by a gang of extraterrestrial cows. The hapless farmer looks on as his farm, his barn, and his chickens are abducted.

In fact, our Invaders Attack from the Planet Moolah slot review unearthed a small detail: the game is merely a slight update of Invaders Return from the Planet Moolah. Some of the alien cows are still in the game, but new ones have been added.

WMS have also made full use of the HD screen technology. As you spin the reels, a giant UFO hovers across the screens. The UFO even has a prize bonus wheel incorporated into the side of it.

If you know WMS's earlier Planet Moolah games, you'll recognize the various symbols. Icons making a return include the low-paying outhouse, mailbox, and milk carton, as well as chickens, a truck, and a trailer. The crazy Midwest characters can pay out as mixed symbols. These include the pet dog, the cowgirl, Grandpa, and Grandma.

Look out for the wild cow symbols too. If they appear stacked on the screen, they will be beamed up by a UFO sitting above the reel. When the cows are dumped back on the screen they may contain a bonus.

A cow featuring a Blast Reels symbol will be beamed up by the mothership. The UFO blasts lasers at the reels, destroying symbols. The icons sitting above then fall into place. At the same time, a prize multiplier at the foot of the reels will increase. If you like slots with a cascading reels feature, this is definitely the slot for you. Other blasts add wild symbols to the reels.

Incidentally, the prize multiplier for consecutive wins is quite generous. Hit three winners in a row and the meter fills up normally. Hit a fourth and you will win 7 free spins. Hit a fifth and you win 10 free games. The meter keeps increasing, awarding players 15, 20, 50, 75, 100, and 200 free spins.

Once you trigger some free spins, the giant screen in Invaders Attack from the Planet Moolah kicks into life. The UFO transforms into a prize wheel and starts spinning. If it lands on the 'We're Multiplying' spot, your free spins will have a random multiplier attached to each spin. This can be as high as 7x. However, our review of Invaders Attack from the Planet Moolah slot showed that a 2x wild multiplier was the most common result.

A fun bonus to hit on the prize wheel is the CowsBack Bonus. If the wheel stops on the 'We Want Our Cows Back' square, your free spins begin. But there's a difference: the human characters will appear at the side of the reels, tossing objects at the UFOs to try and release the abducted cows. Any cows that are released fall onto the reels as additional wilds. The free games continue as normal.

The prize UFO wheel features some good bonuses, particularly the multipliers and the giant symbols that can appear on the reels. However, you really want to be aiming for the Jackpot Abduction space. Hit this and you will have a shot at one of four progressive jackpots.

The progressives are linked and range from the top-paying farmer to the medium cowgirl and lowest pet dog jackpot.

And let's not forget the infamous unicow. In Invaders Return from Planet Moolah, the mythical unicow can make an appearance and add modifiers to your spins. These include additional blast reels and up to 300 free spins. The unicow makes a welcome return in Invaders Attack from the Planet Moolah, but there are now four different types for you to find.

If you are playing online and want to experience these great WMS games for real cash, try Invaders from the Planet Moolah. It's a simple-looking online slot that uses some fun graphics and excellent sound FX. A running theme through all these slots is the cow wild symbol. These stacked symbols can appear on multiple reels to give you big wins. The slot was also one of WMS's earlier attempts at a cascading reels slot.

If you enjoy cascading reels with lots of multipliers, check out NetEnt's popular Gonzo's Quest video slot. It's a volatile slot but is still one of NetEnt's best online slots. The game features reels packed with Incan stones that disappear when you line three or more up on a payline. As you hit consecutive winners, a prize multiplier increases from 1x to 2x, 3x, and 5x.

Casino slot machines today need to be totally immersive and fun to beat the competition. WMS's Invaders Attack from the Planet Moolah is definitely fun and immersive.
