Expansion! Slots

Prepare for an alien invasion with Betsoft's Expansion! slots. This 5-reel, 30-payline game presents invading extraterrestrials in high definition. You can look forward to exciting features in this game, including directional wilds, stacked mystery symbols, and free spins. The following Expansion! slots review covers more on these features and other important aspects.


Expansion! features 5 reels and 30 paylines going across a 5x4 grid. Wins form when matching symbols land in a payline, starting with the initial reel. This slot does a nice job of alerting you to payouts as well with entertaining animations.


Like many depictions of alien invasions, Expansion slots takes place on a farm. You'll see a farmhouse, trees, meadows, and a picket fence in the background. Betsoft has really livened this game up with some great graphics and animations. The UFO zappers and ray guns shoot across the reels during certain features and keep the entertainment going.

Symbols & Maximum Win

Symbols include royals (A-10), a star, planets, and various space rocks. A portal serves as the wild symbol and substitutes for regular icons to create winning combinations. As for win potential, you can win up to a maximum of 1,212x the stake.

Expansion! Slots Features

The Direction Wilds feature happens whenever the same-titled wild symbol lands on the grid. Reels will then grind to a halt, and a ray gun fires in a direction. Wild symbols appear in the path that the ray gun blast follows, while the Directional symbol also becomes a wild.

Stacked mystery symbols turn into the same symbol after a round is over. This effect improves your chances of scoring big wins.

Finally, you trigger free spins when landing 3+ scatters anywhere on the reels. You'll get 8, 12, or 15 free spins for three, four, or five scatter symbols. This bonus offers multipliers, which you can see a display for near the reels. Multipliers range from 2x to 10x, and they cover the entire win for a round.

Betting Options

You can wager between $0.30 and $300 per spin. The autoplay feature allows you to keep the reels spinning for between 5 and 100 rounds.

RTP & Volatility

The Expansion slots RTP is 96.08%, which is slightly above average compared to other online slots. Meanwhile, the volatility carries a medium rating, which isn't surprising given the smaller 1,212x maximum payout.

Play for Free

You don't have to bet anything just to enjoy Expansion! slots. After all, this game offers a free mode wherever it's available. If you visit an online casino and sign up, you'll be able to try Expansion! before risking any money on it. We recommend going this route to ensure that you like the game before betting anything. Assuming you do enjoy Expansion!, then you're one deposit away from playing for real money.

More on Betsoft

Expansion! is another game in a long line of Betsoft online slots. This developer has been around since 1999 and boasts plenty of hit games. A few top Betsoft slots include Alkemor's Elements, Faerie Spells, Jungle Stripes, Macau, Return to Pairs, and Take Olympus. We can't say for sure whether Expansion! will also be another top slot from this developer. However, it at least has a chance of being a success.

Verdict on Expansion! Slots

We give Expansion! slots an 8 out of 10 rating. This game impresses us with its high-quality graphics, multiple features, and fun theme. It also has decent RTP (96.08%) and delivers wins at a reasonable clip (medium volatility). The win potential (1,212x) leaves something to be desired for those who enjoy chasing big payouts. Nevertheless, we still think that Expansion! is worth checking out. Again, you don't even need to make a deposit to try it in demo mode.
