Let’s face it; slot game themes can get a bit stale. There seem to be tons of gaming companies using cookie-cutter slot visuals—just look at how many slots have to do with fruit or a popular movie. That’s why it’s so refreshing to see a slot game like Cosmic Invaders by 2 By 2 Gaming, a slot game with a unique theme and plenty of unique features.

The first thing you’ll notice about this game is the design of the board. 2 By 2 took extra care to make sure Cosmic Invaders gives players that outer space feeling and the results are wonderful. Three invading UFOs hover in space above the middle of this slot game, and the symbols and bonus features give you an extra dose of alien adventure.

Strap on your moon boots and make a playlist of your favorite airy space songs—Cosmic Invaders are on the way.


As far as gameplay goes, Cosmic Invaders is pretty standard, but there are a few bonus features you need to know about. This is a 5-reel slot game with 3 row and 30 paylines. You can set the number of active lines using the colored rectangles on either side of the board or by clicking the +/- under “Lines” at the bottom of the board. You can also set the size of each chip to a value between 0.01 and 0.25. For an easy way to play, you can click “Auto Play” in the bottom-left corner of the game.

The symbols in Cosmic Invaders a bit different from other games. There are 4 symbols that pay out the same; these are the four lowest symbols (10, J, Q, K). The A is a bit higher-paying than these symbols, but still the second worst. From lowest to highest value, the rest of the symbols are: black planet, Earth, satellite, transmitter, and the Cosmic Invaders symbol.

The wild symbol, a green alien, substitutes for any non-special symbol on the same payline. It also pays the highest for a match. The alien picking bonus game is triggered by UFO symbols on reels 1 and 5. This game starts with 5 aliens for you to choose from, each of whom has a different prize.

The scatter symbol, a pink female alien, triggers free spins when you land 3 or more. Landing 3 aliens gets you 6 spins, 4 aliens gets you 7 spins, and 5 aliens gets you 8 spins. During these spins, one entire reel—2, 3 or 4—becomes wild. You can trigger the alien picking bonus game with these spins.

Occasionally, UFOs will turn one of the middle 3 reels wild, giving you potentially massive wins.


If you look around the internet, there are plenty of sites where you can play Cosmic Invaders for free online. Many of these websites even give you the option to play for cash, so you can step it up to the real deal when you think you’re ready to risk your money.

Since the web browser versions of Cosmic Invaders uses Adobe Flash Player, you won’t be able to play it on your smartphone or tablet, only a desktop PC or laptop. There also don’t appear to be any downloadable versions of the game available on Google Play or the App Store.


Overall, Cosmic Invaders by 2 By 2 Gaming is a very well-made slot game with some great features that give it extra value. The sound isn’t great, but the board is very well done and the sounds that indicate big wins will get your blood pumping.

Slots are fun, but the themes can get stale. This outer space-themed slot game goes beyond using a space-themed board and cosmic symbols; with UFOs above the middle 3 reels and a couple of really cool space-age bonus features, Cosmic Invaders offers a unique slot experience that you won’t find elsewhere.

But most of all, this game is really fun. It seems like a bonus game or cool feature comes into play every other spin, and there’s definitely a lot of potential for some absolutely insane wins.
