Expansion RTP and Wagering
Expansion is played on 5 reels, 4 rows, and 30 fixed paylines. You can wager between £0.30 and £300 per spin.
In Expansion, you need to land three, four, or five identical symbols on any payline to win a cash prize. You can also trigger various features while spinning in the base game: Stacked Mystery Symbols, Directional Wilds, and a Free Spins feature.
Expansion has medium volatility, and prizes are smaller but more frequent than those in highly volatile slot games. Its Return to Player (RTP) rate is just above average at 96.08%, which means that Expansion theoretically pays out £96.08 for every £100 wagered (on average).
You could win up to 2,171x your bet in Expansion. The multipliers in the Free Spins feature can increase your chances of winning a bigger prize, but as most of the prizes are so low, the likelihood of hitting that maximum payout is slight.

Expansion Symbols and Audio & Video Design
Expansion has a colourful space theme revolving around planets and other celestial objects. The setting is a beautiful plot of land, complete with a picturesque home, towering trees, and fields. An astronomer’s telescope sits in the bottom-left corner, beside the reels.
Expansion’s graphics are vibrant, packed with striking colours, and brilliantly animated. The audio is just as strong as the visuals, with mysterious, exciting music and some retro sci-fi effects. For example, the sound of ray guns blasting symbols to turn them into Wilds could be from a classic movie.
There are 12 symbols in Expansion. These include a Wild, a Scatter, and 10 standard symbols awarding various prizes. The Gold Star symbol is the most valuable, worth up to 1,000 coins (when playing at the maximum stake).
The Wild symbol substitutes for all symbols except the Scatter. The Scatter triggers the Free Spins feature.
Expansion Mobile Features
Expansion was developed in HTML5, so you can play it via mobile browser on any smartphone or tablet. It looks just as sharp and features the same user-friendly controls. You can play Expansion in landscape or portrait, and the controls change position to give you the most convenient experience in both modes.
Expansion Bonus Features
Expansion includes a strong variety of bonus features that expand the gameplay and bring you more chances to win. You can land Stacked Mystery Symbols for help with winning combinations, and Directional Wilds that add more Wilds to the reels. There are up to 15 free spins available, too.
Stacked Mystery Symbols
Before each spin, all five reels contain Stacked Mystery Symbols that are replaced with a random symbol. Every Mystery Symbol turns into the same symbol to build winning combinations. Any standard symbol may replace a Mystery Symbol, from the 10 to the Gold Star.
Directional Wilds
When a Directional Wild symbol appears, all reels stop and the Directional Wilds feature triggers. A ray gun emerges and fires in any one of the eight directions around it. Wild symbols are placed in all positions along that line, and the Directional Wild becomes a standard Wild.
Once all Wild symbols have been placed, wins are evaluated then awarded. The Directional Wild symbol can land on reels 2 to 4.
Free Spins
Land 3, 4, or 5 Scatters anywhere on the reels to win 8, 12, or 15 free spins, respectively.
Directional Wilds have one extra blast from the ray gun in the Free Spins feature. The ray gun fires once as normal, Wilds are placed in the relevant positions, then the ray gun fires in any of the other seven directions. The Directional Wild becomes a Wild as before.
Random multipliers apply to the Free Spins feature: 2x, 3x, 4x, 5x, 8x, or 10x. The current multiplier is shown on an indicator, and they are updated with every free spin. Multipliers apply to the whole win for any winning free spin. You can retrigger the feature to get more free spins, too.
Buy Feature
Use the Buy Feature option to play the Free Spins feature for a price. The cost depends on whether you want 8, 12, or 15 more free spins.

Expansion Final Thoughts
Expansion is a dynamic space-themed slot that looks spectacular on any screen, and it boasts great features. With its medium volatility and 96.08% RTP, the chances of winning in Expansion are decent, though most prizes will be on the small side.
The Directional Wilds, Stacked Mystery Symbols, and Free Spins features all complement each other well. They may boost your chances of winning by adding Wilds and matching symbols to the reels on any spin. The top payout is fairly modest at 2,171x, but the bonuses can help you rack up winnings.
With all this in mind, Expansion is easy to recommend for casual players and high rollers alike.
