Expansion! - A slot that's truly out of this world
Picture this: You're relaxing in your garden, staring up at the stars... and BAM - UFOs, aliens, laser beams, wild wins. That's the theme of Expansion! in a nutshell. It's very spacey, but with a fun, animated twist that doesn't take itself too seriously.
The design is clean but bold. The icons pop with a colourful glow, and the animations - especially when those Directional Wilds are firing - feel exciting every time. You've got stars, planets, weird glowing asteroids, and a mysterious brown moon-planet thing that honestly looks like something out of a 90s space cartoon.
But the real kicker? Those Directional Wilds. We'll get to them in a moment, but just know that they're the star of the show.

How to Play - Not Rocket Science, promised
The game runs on a 5-reel, 4-row layout with 30 paylines - pretty standard, but with just enough room for some interesting patterns.
Here's the basic drill:
- Pick your bet size (you can go low or high, it's up to you).
- Hit the spin button.
- Look for symbols that line up from left to right across the pay lines.
- Get 3 or more of the same symbol in a row and you're paid.
It's not too complicated. You get a good feel for what's going on after just a few spins. And once the wild features kick in? You're hooked.
Paytable: What the galaxy pays you back
So, let's talk money. Here's what each symbol is worth when you get 5 of them:
- Star - 3.3 times your bet (biggest hitter in the base game)
- Planet - 2.6 times your bet
- Green Asteroid, Purple Moon, Brown Planet - 1.3x your bet
- A, K, Q, J, 10 - All pay 0.8x for 5 of a kind
So yes, your winnings really start to heat up when you combine these with bonus features like Wilds and Multipliers. On their own, the payouts are decent but not massive - which makes sense as Expansion! is all about the features.

The real action: Bonus features that shine brighter than a supernova
This is where Expansion! really turns up the heat. The base game is fun on its own, but let's face it - it's the bonus features that really make this thing pop. Betsoft hasn't held back here. They have thrown in a handful of clever, interactive mechanics that will keep you on your toes and honestly make every spin feel like something big could happen. Let's break down what makes these features tick:
Directional Wilds - The main attraction
If there's one feature to get excited about, it's Directional Wilds. These things aren't just regular ordinary Wilds. They're basically UFOs with laser beams, and they are quite serious.
Here's how they work:
- When a Directional Wild symbol lands on the reels, everything stops - you'll see this funky looking ray gun thing appear right on top of the Wild.
- It starts spinning, like a space compass, and then randomly chooses one of the 8 possible directions (up, down, diagonal - you get the idea).
- Once it has chosen a direction, it shoots. A laser beam shoots across the reels, turning every single symbol it touches into a Wild.
- And as a bonus? The original Directional Wild that triggered the whole thing also turns into a regular Wild at the end of the effect.
It's such a cool moment when it happens. You get that thrill as you wait to see where the beam goes, and sometimes it goes exactly where you want it to - right through the heart of the high-paying symbols. Other times... well, space is unpredictable.
The best part? You can land more than one Directional Wild on the same spin. Yep - multiple lasers shooting off in different directions, crisscrossing the reels and stacking up Wilds. That's when things really start to get explosive.
Free Spins - with a multiplier twist
You knew it was coming - the Free Spins feature. But Expansion! adds its own little twist to keep things exciting.
Here's how it's triggered:
- Get 3 or more Scatter symbols anywhere on the reels in a spin. The more you get, the more spins you unlock - up to 15 Free Spins if you hit the max.
But here's the fun part:
- Each Free Spin has a random multiplier that changes with each spin. The multiplier ranges from 2x to 10x and applies to everything you win on that spin.
So imagine this: You've got a Directional Wild that turns part of the board Wild, a decent line hit, and then - bam - a 10x multiplier lands. That's how the big wins start to pile up. It's not just about triggering Free Spins, it's about getting the right combination of features and timing.
The Free Spins rounds are also fast and exciting. They don't drag, and with the multiplier changing every spin, you never feel like you're just going through the motions. Every spin keeps you guessing.
Stacked Mystery Symbols - The Silent MVP
Okay, so this one doesn't get as much attention, but behind the scenes it's pulling its weight.
Every spin in Expansion! starts with a little mystery: some of the reel positions are marked as Stacked Mystery Symbols. You can't tell what they are at first - they just show up as question marks or some sort of placeholder symbol.
Then, when the spin starts, all these Mystery Symbols turn into the same matching symbol for that spin. It could be anything - one of the high paying symbols or a low one.
Why is this great? Because it gives you a much better chance of getting long combos across the reels. When you get a bunch of symbols in the centre of the grid that all turn into stars or planets - that's when the big paylines come alive.
And with new mystery symbols appearing on every spin, there's always that extra layer of anticipation before the reels start spinning.
Buy Feature - Skip the line for Free Spins
Let's face it, sometimes you don't want to sit and wait for the Free Spins to start. That's where the Buy Feature comes in.
If you're feeling a little impatient - or maybe just in the mood for a roll of the dice - you can pay a set price to buy your way into Free Spins mode immediately. It's not cheap (it never is), but it's a guaranteed shot at the bonus round, and for many players it's worth it for the action alone.
And yes, you get all the same goodies: 15 free spins max, the multiplier mechanic and all the usual features within the round. It's just a shortcut for when you want to get straight to the point.
Pro tip? Only use the Buy feature if you've got the balance to do it - don't go all-in unless you're ready to go crazy.
Wrapping up the features
So yes, Expansion! doesn't mess around when it comes to features. You've got:
- Laser-blasting Wilds that feel like a little event every time they land,
- Free Spins with ever-changing multipliers to keep things dynamic,
- Mystery Symbols that offer extra potential on every spin,
- And a Buy Feature for when you're feeling bold.
It all adds up to a slot experience that's fun, unpredictable and frankly quite addictive. Every time you spin, there's that little thrill of something cool happening. That's what makes a great slot experience.
If you're the type of player who loves interactive features, not just passive spinning, then this game is made for you.
Spin smarter, not harder - a little cosmic guidance
All right, slots are mostly about luck - we all know that. But you can still spin smarter:
- Manage your bankroll - especially if you're tempted by the buy feature. It's fun, but it can quickly eat into your bankroll.
- Look out for Mystery Symbols - These can really pay off, especially when you see high paying symbols stacked up on the reels.
- Use the Buy feature sparingly - It's tempting, but not always worth it. Wait until your balance is healthy.
- Play during the bonus rounds - It's during the free spins with multipliers that you'll see the real potential for bigger wins (especially with up to 10x multipliers).
- Medium volatility = Be patient - You'll get some dry spells, but also a good balance of smaller wins and the occasional big one.
Expansion! Slot Machine - A wild ride through the galaxy
Honestly? Expansion! is just a blast to play. It's not overly complex, but there's enough going on to keep things interesting. The Directional Wilds feel fresh and fun, the visuals are eye-catching without being overwhelming, and those multiplier-packed Free Spins can come in handy.
Is this the kind of game where you'll hit 1000x wins every session? Nah. But it's got great pacing, cool features and solid winning potential - especially considering it sits at a cosy 96.08% RTP.
If you're into space themes, cool Wild Mechanics, or just want something that feels a little different from the same old fruit machine layout, I say give Expansion! a try. Just don't blame if you lose track of time and end up chasing UFOs until 2am.Space FAQs: What every cosmic spinner wants to know
