Expansion! Slot Coming Up

Expansion! Free Demo Play

Expansion! slot developed by BetSoft and released in February 2023 transports players into a paranormal experience in search of lucrative UFOs on the reels.

Inspired by the world of astronomy and aliens, BetSoft’s Expansion! slot takes place in the backyard of a country house, a quiet place far from any light pollution. You would think that this would be the ideal place for stargazing, but we never imagined that we would receive an unexpected visit from aliens. These aliens will be very useful for the players, adding action and surprises to the gameplay with different features that we will see in the following review.

The Best Online Casinos & Bonuses to Play Expansion! for Real Money

Expansion! - Slot Review

Expansion! is played in this unusual atmosphere on a grid consisting of 5×4 reels and 30 paylines. With a medium volatility, the game has an RTP of 96.08% and plans to deliver winnings up to 2171x the bet at the maximum. To achieve such results, you will have to take advantage of the various bonus features including Free Spins with multipliers, Stacked Mystery Symbols and Directional Wilds propagating jokers in all directions.

But before we get to all that, let’s focus on the beginning. First of all, you’ll need to wager between $0.60 and $30 per spin to play Expansion. Once you’ve selected your bet, one click on the play button is all it takes to go into this strange world of UFOs and astronomy. Get 3, 4 or 5 identical symbols from left to right to win a prize. The A, K, Q, J and 10 symbols pay smaller wins than the planets or the star, so keep an eye out for the three special symbols including the mystery symbol, the wild and the scatter that cause the different bonuses.

Stacked Mystery Symbols

Each reel may contain positions occupied by stacked mystery symbols. These symbols will all be replaced by another identical type of random symbol before each spin begins.

Directional Wilds

The Wild can substitute for any symbol except the Scatter. When it appears on the reels and all reels have stopped, the special feature will be triggered. A laser gun will start spinning and shooting in one of 8 directions around its position. Wilds will then be placed along the path traced by the laser beam and the Directional Wild symbol will also be turned into a wild. Then the winning combinations can be evaluated.
