Meet Invaders Blitz

Invaders Blitz is a slot machine cooked up by Light & Wonder, serving as a sequel to their quirky alien-themed Invaders Takeover that hit the scene roughly a year ago. Picture this: you’re back inside a spaceship, peering out into the vast black void peppered with twinkling stars. Earth was under siege last time, thanks to some rather unusual extraterrestrial bovines, and guess what? Those pesky alien cows have moseyed back, only this time they’re packing a heftier punch. Now dubbed Cash Cows, these critters can rake in up to a whopping 1,000 times your bet. Collecting them involves snagging various Collect Symbols that kick off the electrifying Lightning Collect Feature. Plus, Light & Wonder throws in a couple of Free Spin modes for you to pick your poison: the Symbol Eliminator Free Spins or the wilder Cow Collect Free Spins. Which side are you on?

Before you dive headfirst into the cosmic chaos at your favorite online casino, why not take the game for a spin in the free demo perched at the top of this page? No harm in a little practice, right?

Theme, Gameplay, and Payouts

Invaders Blitz rolls out as a video slot boasting 6 reels, 4 rows, and a hefty 4,096 ways to win. Betting kicks off at a modest 0.1 and can climb all the way up to 20. The default RTP clocks in at a neat 96%, though if you’re feeling adventurous, versions with 94%, 92%, and even 90% are floating around. With a medium volatility setting, the jackpot maxes out at a staggering 11,000x your bet.

Visually, the backdrop is a star-speckled black canvas of outer space. Front and center, six reels framed in green spin away, each topped with a spaceship. Off to the left, a tank houses one of those alien cows, while the game’s logo lounges in the upper right corner. The soundtrack? Quirky enough to make you grin as you hit the spin button. Wins come from landing three or more matching symbols on adjacent reels, starting from the far left. Oh, and it’s fully playable on mobiles, tablets, and desktops alike.

The low-paying symbols are your classic 9, 10, J, Q, K, and A, dishing out between 0.8x and 1.6x your bet for six-of-a-kind combos. On the flip side, the high-paying icons include a red planet, a space gun, an alien, a mad scientist, and the game’s logo itself, rewarding anywhere from 3x to 8x the bet for six matching symbols. Don’t forget the Wild Symbol—a spaceship that can stand in for all regular symbols but steers clear of Cash Cows, Collect, or Bonus Symbols.

What goodies does Invaders Blitz pack?

Expect Wild Symbols, Cash Cows, Lightning Collect, the Cowtainer Meter, and Free Spins to keep things lively.

Wild Symbol

The Wild is a spaceship that substitutes for all regular-paying symbols to help you form winning lines. It won’t replace the Black, Brown, or Pink Cash Cows, nor the Normal Collect, Respin Collect, Multiplier Collect, or Bonus Symbols.

Wilds can pop up on every reel except the very first one on the left and come with a 2x multiplier during the Symbol Eliminator Free Spins.

Cash Cow

Cash Cow symbols can show up on all reels—except when you’re in the Symbol Eliminator Free Spins mode. The Black Cash Cow pays between 0.5x and 20x your bet, the Brown Cow ranges from 4x to 100x, and the Pink Cow is the big cheese, offering between 8x and a jaw-dropping 1,000x your bet.

To snag these cows, you’ll need to land any of the Collect symbols—Normal, Respin, or Multiplier Collect. If a Cash Cow lands alongside a Lightning Collect symbol, you get paid instantly. Otherwise, if no Lightning Collects are around, the cows might randomly get beamed up into the Cowtainer Meter.

Lightning Collect

Lightning Collect symbols can appear on reels 1 and 6 during both the base game and Cow Collect Free Spins. They come in three flavors: Normal Collect, Respin Collect, and Multiplier Collect.

When a Respin Collect lands with any Lightning Collects, it kicks off first, triggering a respin. Once all respins wrap up, the Lightning Collect symbols activate, scooping up all Cash Cow symbols starting from reel 1.

Normal Collects tally up the value of all Cash Cows on the reels and pay out the total. Respin Collects lock all Lightning Collect and Cash Cow symbols in place during the respin, and after it ends, they act like Normal Collects. If three or more Bonus symbols land during the respin, they stick around until the respin finishes, then the Free Spins Feature Picker kicks in.

Multiplier Collects crank up the total value of collected Cash Cows before paying out, with multipliers of x2, x3, and either x4 in the base game or x5 during Cow Collect Free Spins.

Cowtainer Meter

When a Cash Cow lands without any Collect symbols, it gets scooped up by the Cowtainer Meter, which keeps a running total of all collected cows’ values.

Once the meter hits 75 or more, a Bonus Wheel spins into action, awarding anywhere from 1% to 100% of the meter’s value. After the spin, the meter refills to 10% of the triggered value. If both the Bonus Wheel and Free Spins trigger simultaneously, the Bonus Wheel takes the spotlight first.

Free Spins

Bonus Symbols can pop up on any reel. Land three or more anywhere, and you unlock the Free Spins Feature Picker, letting you choose between two Free Spins modes. Depending on how many Bonus Symbols you land—3, 4, 5, or 6—you’ll get 2, 4, 6, or 9 Cow Collect Free Spins or 8, 12, 16, or 20 Symbol Eliminator Free Spins.

Cow Collect Free Spins

This mode guarantees at least one Lightning Collect Symbol on every spin. The reels here only show Lightning Collect Symbols, Cash Cows, or blanks. Land two Lightning Collects, and you snag an extra spin.

Symbol Eliminator Free Spins

Here, you can boot the lower-paying symbols off the reels by hitting winning combos with them in order—starting with 9, then 10, J, Q, K, and finally A.

Higher-paying symbols are safe from elimination, and this feature can’t be retriggered.

Final Thoughts on Invaders Blitz

Invaders Blitz is a bit of a mixed bag theme-wise. You’ve got spaceships zipping around, reels glowing like a neon sign, and alien cows with dollar signs in their eyes all at once. It’s playful, sure, but might strike some as a tad too out-there. The gameplay mechanics aren’t your run-of-the-mill either—they’re a touch more intricate and can throw curveballs just when you think you’ve got the hang of it.

Choosing between the two Free Spins options adds a nice twist. If you’re the type who likes steady, puzzle-like progress, the Symbol Eliminator Free Spins will be your jam. But if you’re chasing that adrenaline rush, the Cow Collect Free Spins—with their high volatility—are calling your name. Toss in the Cowtainer Meter, Lightning Collect symbols, and hefty multipliers, and you’ve got a slot that rewards both patience and guts.

While it looks almost like a carbon copy of Invaders Takeover, the features here are quite different. Honestly, the previous game’s features felt a bit more cohesive, and Invaders Blitz can get a little tangled up at times.

All in all, Invaders Blitz from Light & Wonder doesn’t exactly flip the slot world on its head, but if you’re into feature-rich slots where alien cows roaming spaceships is just another Tuesday, this one’s worth a whirl.
