WILD
This is the WILD symbol and substitutes for all symbols for the purpose of winning combinations except for SCATTER. It can appear on reel 3 during the base game and on reels 2, 3 and 4 during the FREE SPINS feature. The WILD symbol does not substitute unless it hits or reaches the bottom, marked row. Above the marked row it is shown as inactive and it becomes active once it reaches the bottom row. The WILD symbol can carry a random multiplier of 1x, 2x, 3x, 5x, 10x or 25x.

Alien Invaders features

Tumble Feature
The TUMBLE FEATURE means that after every spin, winning combinations are paid and all winning symbols disappear. The remaining symbols fall towards the bottom of the screen and the empty positions are replaced with new symbols coming from above. Tumbling will continue until no more winning combinations appear as a result of a tumble. All wins are added to the player's balance after all of the tumbles resulted from a base spin have been played.
Win Multiplier Feature
Every spin starts with a multiplier of 1x. Every 10 symbols that explode during tumbles or are exploded by a SCATTER add +1x to the win multiplier. The multiplier that WILD symbols carry is also added to the win multiplier when a WILD symbol reaches the bottom marked row. The current win multiplier applies to the winning combinations as they happen.
Free Spins
Hit 3 or more SCATTER symbols across a base game spin and all tumbles resulted from it to trigger the FREE SPINS feature and win 7 free spins plus an additional 3 for each SCATTER symbol beyond the 3rd. The amount of symbols hitting on each reel during the FREE SPINS round always starts with 3 and after every spin it might randomly increase by 1 on a random reel, up to maximum 5 on a reel. Those reels will then stay at that size until the end of the round. All increases of the win multiplier achieved during any free spin persist throughout the round. Any SCATTER symbol that hits or reaches the bottom, marked reel during the round, awards 1 additional free spin. The WILD symbol in the FREE SPINS feature can carry a random multiplier of 1x, 2x, 3x, 5x, 10x, 25x, 50x or 100x. Special reels are in play during the feature.
Max Win
The maximum win amount is limited to 5,000x bet. If the total win of a FREE SPINS round reaches 5,000x bet the round immediately ends, win is awarded and all remaining features are forfeited.
Ante Bet
The player has the option to select the bet multiplier. Depending on the selected bet, the game behaves differently. The possible values are: Bet multiplier 25x - the chance to win the FREE SPINS round naturally is doubled. More SCATTER symbols are present on the reels. The BUY FREE SPINS feature is disabled. Bet multiplier 20x - Normal play.
Buy Free Spins
The FREE SPINS round can be instantly triggered from the base game by buying it. Pay 65x total bet to trigger the FREE SPINS feature. Pay 400x total bet to trigger the SUPER FREE SPINS feature. In the SUPER FREE SPINS feature, the win multiplier starts at 50x.
Alien Invaders rules, as the game states them

The game is played on a grid of 5 vertical reels with 3, 4 or 5 symbols randomly hitting on each reel at every spin. The bottom row of symbols is always marked.

Wins occur when 3 or more symbols of the same type hit on the bottom, marked row of the reels.

When that happens, the reels that have winning symbols on them become active and all instances of the winning symbol on the active reels count for creating winning combinations.

High volatility games pay out less often on average but the chance to hit big wins in a short time span is higher.

Only the highest win is paid per winning combination.

When winning with multiple combinations all wins are added to the total win.

All wins are multiplied by base bet.

All values are expressed as actual wins in coins.

Alien Invaders Overview

Alien Invaders is a high volatility slot by Pragmatic Play with an RTP of 96.5% . . Play Alien Invaders for free on Slottomat, compare the core stats quickly, and browse trusted slot offers available in your market.


Alien Invaders Slot Overview



First thing that caught my eye? The high volatility paired with a 96.5% RTP. That's above the 96% industry average, which translates to fair value on your spins. With bets from $0.01 to $100, both casual players and high rollers can find their sweet spot.


The theme is where it shines. Sharp visuals and arcade-style sound effects pull you right into a classic alien shooter. If you're bored of the usual fruit or Egyptian themes, this free slot is a breath of fresh air. My advice? Fire up the pragmatic play demo slots free version above first. It's the smart move to get a feel for this high-volatility beast before spending a dime.


Pragmatic Play sticks to a proven formula here, but the alien invasion twist keeps it fresh. You've got a 5-reel grid where wins come from matching symbols reaching the bottom row and exploding, not from fixed paylines. No fussing with settings—every spin covers all lines automatically. Just set your bet and launch the attack.


The symbols are all on-theme. Lower values are classic card ranks, styled to fit. The premium icons? Various alien invaders and themed imagery. The design is crisp and colorful, exactly what you'd expect from this developer, and it looks great on any screen.


Wild symbols are your best friend here, substituting for regular symbols to stitch together winning combos. In a high-volatility game like this, they can turn a near-miss into a real win. Scatters are your ticket to the big bonus features, so keep your eyes peeled during the base game.


Spin speed is customizable, autoplay is available, and the interface is clean. Everything you need is right there, no menu-digging required.


Multipliers often come into play, especially in bonus rounds, boosting wins significantly. Just remember the high volatility trade-off: longer dry spells, but much bigger payouts when features hit. Understanding that rhythm is key.

RTP, Volatility & Payout Potential


Here's the breakdown: that 96.5% RTP is a slight but meaningful edge above average. When you're looking at high payout slots, every decimal counts. It's not the highest rtp slots pragmatic play free offers, but it's firmly in the "respectable and fair" category.


The high volatility is the real story. Don't expect a steady drip of small payouts. You're here for the feature-triggered jackpots.


A $1 bet could net $5,000; a $10 bet, $50,000. But here's the reality check: you need the balance to survive the variance. Betting $1? Bring $100-$150 to ride out the waves.


Compared to other Pragmatic Play high-volatility titles, Alien Invaders is mid-tier for max win potential. Some newer games chase 10,000x+, but 5000x is nothing to scoff at. The 96.5% RTP is consistent across all bet levels, which is great—you get the same mathematical fairness whether you're betting pennies or dollars.


Practically speaking, your balance will swing. You might burn through 50 spins with nothing, then hit a bonus that recoups it all and then some. That's the high-volatility thrill. If you enjoy chasing bigger wins over grinding small profits, this alien invaders free slot is ideal for you.

Bonus Features & Special Symbols in This Pragmatic Play Slots Free Demo


This is where the Alien Invaders free slot truly earns its stripes. Wilds pop up regularly in the base game, keeping things interesting. But the real excitement starts with the scatter symbols.


Land three or more scatters, and you'll trigger the main event—usually a free spins round or special bonus mode. The trigger is standard: scatters can land anywhere, no payline needed.


Once you're in the bonus, things heat up. Free spins often come with climbing multipliers or special wilds (sticky or expanding) that dramatically boost your chances.


The features aren't generic. They're woven into the alien invasion theme, making it feel like you're progressing through levels of an attack. The audio and visuals intensify, creating a genuine sense of excitement. This is what separates the best pragmatic play slots free offerings from the pack.


Multipliers can apply to single wins or an entire round. With high volatility, these bonuses aren't frequent—you might spin 100-200 times between them—but they pack enough punch to make the wait worthwhile. Some rounds even include collection mechanics or progressive features, adding a layer of strategy beyond simple spinning.

Playing Strategy for High Volatility


If you're new to high-volatility slots, Alien Invaders will teach you a quick lesson in respect. The single most important thing is balance management.


Break it down practically. If your bet is $0.50 per spin, have $50-$100 ready for that session. Coming in with $20 is a recipe for busting out before the good stuff happens. High volatility is a paid admission for the chance at bigger wins—it demands patience and proper funding.


Session length strategy matters, too. The middle ground is often where frustration sets in.


Match your bet size to your goals and balance. With $100, you could bet $1 for 100 spins or $0.50 for 200 spins. More spins mean more feature chances, but smaller bets mean smaller wins. My rule? Start comfortable and only increase your bet if an early feature puts you ahead. Never chase losses by upping your stake—that's a fast track to zero.


Who's this for? Risk-tolerant players who get a thrill from the *potential* of a big win, not the guarantee of frequent small ones. If downswings frustrate you, stick to low or medium volatility. But if you understand variance and love that bonus-round rush, this is your game.


One final, crucial tip: use the demo. Put in 500-1000 free spins to learn the game's rhythm, feature frequency, and win patterns. You'll develop a gut feeling for the volatility. The pragmatic play slots free demo exists for this exact reason—so use it.
