Embark on an Intergalactic Quest in Alien Invaders.
On every spin, 3–5 symbols can land on each of the five reels. When at least three matching symbols land on the bottom row, those reels become active, and all matching symbols on those reels form a winning combination and explode.
If a scatter symbol reaches the bottom row, it explodes alongside symbols immediately adjacent to it horizontally, vertically, and diagonally. Wild symbols on reel three pay out when they hit the bottom row and can carry a multiplier up to 25x.
Every spin in the base game starts with a 1x win multiplier which increases by +1x for every 10 symbols that explode during the spin. Any multipliers carried by wilds is also added to the total if they reach the bottom row.
Landing 3 scatters awards 7 free spins, with an extra 3 spins for each additional scatter. During the bonus game, win multipliers persist between spins and can carry up to 100x multipliers.
What to Expect:
- Land three matching symbols in the bottom row to activate those reels and form a winning combination.
- Every 10 symbols that hit increases a win multiplier by +1x for that spin.
- 3+ scatter symbols trigger the bonus game where the win multiplier remains in between spins.

Long Description
Alien Invaders is a thrilling space-themed slot that takes you on a cosmic adventure filled with explosive wins, tumbling reels, and intergalactic bonuses. Played on a 5×3 reel setup, the game offers a dynamic mechanic where 3–5 symbols can appear on each reel, creating opportunities for massive chain reactions.
The core gameplay centers around the bottom row activation mechanic—when three matching symbols land on the bottom row, those reels become active and any matching symbols on them will explode for wins. The cascading effect continues as new symbols drop in, potentially triggering additional wins.
Special attention should be given to the wild symbols that can appear on reel three. When they reach the bottom row, they not only pay out but can carry multipliers up to 25x. This becomes even more potent when combined with the progressive win multiplier in the base game, which starts at 1x and increases by +1x for every 10 symbols that explode during a single spin.
The real excitement begins when three or more scatters appear, launching the bonus feature with 7 free spins, plus 3 extra spins for every additional scatter. In the free spins round, the win multiplier doesn’t reset between spins and can climb as high as 100x, creating a high-volatility environment where massive wins are possible.
With a maximum win potential of 5,000x your bet, max exposure of $1.2 million, and a volatility rating of 5/5, Alien Invaders offers an adrenaline-packed slot experience. The hit frequency in the base game is 1 in 2.90 spins, ensuring fast-paced action, while the rare top prize has odds of 1 in 27 million spins—a true interstellar jackpot for lucky players.
Visually, the game delivers a vibrant outer-space aesthetic, complete with UFOs, alien planets, and captivating animations that immerse you in its galactic theme. Whether you’re chasing frequent base wins or aiming for astronomical bonus payouts, Alien Invaders is a must-play for fans of high-energy slots with unique mechanics.
