About Little Green Men Slot Game

Little Green Men was one of a slew of slot machines launched by International Game Technology (IGT) in 1999. When you play Little Green Men, you’ll see a set with a 5 reels, 9 paylines slot setup.

Little Green Men’s rich, cartoonish graphics are another feature that sets it apart. Fruits, which have long been a staple of slots, are transformed into planets in this game.

The Laughing Moon wild symbol, Keep Out sign scatter, green alien bonus, and Abducted newspaper bonus are all important symbols to search for.

The setting for this bonus game is a typical rural, desert kidnapping scenario. This theme is reinforced by an eerie, outer-space jingle that plays while the reels are spun.

How to Play Little Green Men Slots Online

Another aspect that contributed to the success of Little Green Men slots was the inclusion of a second-screen bonus round.

When IGT launched this slot game, this was yet another groundbreaking feature.

In the first Little Green Men bonus round, you’re presented with two flying saucers and must pick the correct one to win a prize.

If you choose the correct saucer, you will continue to compete for more prizes; if you choose the incorrect saucer, the bonus round will end.

Interactive Features

IGT later updated the slot machine to include two bonus rounds.

Bonus Round 1

Landing three alien symbols anywhere on the reels activates one bonus round. Then you’re taken to a nighttime television, where ten flying saucers are shown.

The aim is to keep selecting saucers with prizes, and each right pick awards you between 75 and 500 coins. Only one of the saucers ends the round, but if you choose the wrong one, you’ll get ten consolation credits for each saucer that remains on the screen.

Bonus Round 2

When three or more Abducted newspapers appear on the reels, the other bonus round is enabled.

This will take you to a bus stop, where you will find a dog, an old cowboy, a young girl, a hillbilly, and a diner waitress. An alien ship will arrive and beam up one of the humans or dogs you choose.

The unique feature of this bonus round is that your prize is announced in a brief newspaper report about the kidnapping. The diner waitress, for example, will be featured on the front page with the headline “500 credits.”

What Symbol Triggers the Little Green Men Slot Bonus Free Spins?

The free spins feature is not included in the Little Green Men slot.

Paylines and Stakes

There are nine pay lines in the original Little Green Men slot machine. You can also bet five coins per pay line, for a total of 45 credits on a single spin.

When Keep Out signs appear anywhere on the reels, they multiply the payouts by 2x with two symbols, 10x with three symbols, 25x with four symbols, and 200x with five symbols.

Little Green Men’s bonus rounds are both random, as you’d expect from an older slot, and there’s no talent involved.

Even by today’s standards, the fact that you can access two-second screen bonus rounds is excellent. When it was released in 1999, Little Green Men was ahead of its time. 

As compared to slots of the time, this game’s graphics, sounds, sound effects, and second-screen bonus round put it on another level.

Even today, the original Little Green Men family reunion holds its own against some of the most common slots in both brick-and-mortar and online casinos.
