Welcome to Expansion! Slot Machine

Right off the bat, we can see that Expansion! is a beautiful slot with a relaxing and calm vibe. Betsoft Gaming has tried to give you a fun game with decent potential. They aren’t trying to stand out, but the slot does have solid features like Free Spins and Directional Wilds.

You will get to see a layout with 5 reels, 4 rows, and 30 paylines in this casino game. The extra number of rows and higher number of paylines than usual will help you get some extra opportunities to win big.

The Free Spins feature is where this slot reaches its peak, as you get to enjoy Multipliers, and the power of the Directional Wilds is also boosted. It is nice that they have allowed players to buy free spins, which can be great for the high rollers who want to get into the action right away.

Let us now move on to the graphics and theme of this slot machine.

Gameplay of Expansion! video slot


Extraterrestrial Theme and Superb Design

Theme and Design

At first, you will see a beautiful background with a house, trees, grass, and a telescope. However, the symbols on the reels will indicate that this slot is not about the beautiful scenery. In fact, this slot is about aliens, UFOs, and our unlimited curiosity.

We like the animation for spinning the reels, how the background switches when the Free Spins trigger, and the soothing background music. The symbols fit the theme perfectly, as mysterious alien planets and UFOs appear as symbols.


The high-paying symbols are four alien planets and a star, which will pay you 1.33x to 3.33x of your stake for landing a five-of-a-kind winning combination.

The low-paying symbols are card symbols designed to resemble space stations. The card symbols will pay you 0.833x of your stake for landing five matching symbols in a winning combination. So you will lose money for landing one winning combination with card symbols, but the features and other symbols will help you generate a healthy profit.

The Wild symbol is a UFO, and the Scatter is a red planet with a golden ring.

Explosive Bonus Features

Clearly, there is no shortage of bonuses in this game, and your winnings can be pretty high. So, let us understand how these features can reward you.

Stacked Mystery Symbols

The game doesn’t highlight them, but Stacked Mystery Symbol positions can be present on all reels. All of the Stacked Mystery Symbol positions will be filled with the same symbol so that you can easily get a big win. Note that these positions can only be filled with regular symbols, not Wilds or Scatters.

Directional Wilds Feature

The Directional Wild can land on the reels randomly and then fire its ray gun in one out of eight directions around its position. The symbols hit by the ray gun transform into Wilds, and then the Directional Wild also transforms into a Wild.

After the transformations are complete, you will be paid any win from the spin. This special Wild can only appear on the middle reels.

Free Spins Feature

You need to land at least 3 Scatters to trigger Free Spins. Here is a breakdown of how it works:

  • 3 Scatters: 8 Free Spins
  • 4 Scatters: 12 Free Spins
  • 5 Scatters: 15 Free Spins

The Directional Wilds become stronger during this bonus as the ray gun spins and fires in 2 different directions instead of just one. So you can get plenty of Wilds in positions that guarantee wins.

The Free Spins also have different Multipliers that will apply to the win for a particular spin. You can see the Multiplier value on the bottom right side, and it can be between 2x to 10x. Basically, you are guaranteed a win worth at least twice of what you would win in the base game.

Bonus Buy Feature

The Bonus Buy feature is for those who would like to play the Free Spins by paying for them. Here are the options you will get in this feature:

  • 8 Free Spins: 60x of your bet
  • 12 Free Spins: 90x of your bet
  • 15 Free Spins: 113x of your bet
