Play Alien Invaders for Free

There’s a charming style here, with a cute, bug-eyed, bat-eared alien floating to one side of the reels against the backdrop of his desert homeworld. Play the Alien Invaders slot online and it’s what happens on the reels that counts, as four strange creatures shaped like high card symbols, plus four cute E.T.s with their tongues hanging out drop onto the grid.

It’s a desktop and mobile game that you can explore at the best Pragmatic Play online casinos.  

You can play with minimum stakes of 0.20 and a maximum of 300.00. Here’s what you get from each symbol when it’s part of a win, shown as a multiple of the total stake –

How you get those wins is as unusual as the aliens themselves. From three to five symbols drop onto each reel of the 5x5 grid, where blue light highlights the bottom row. Only the symbols on this row count, and you need three of the same type to collect a prize. The purple wild helps by acting as other Alien Invaders online slot symbols when needed but only activates when it hits the bottom.

Any reels above a winning symbol then activate, and if more matched symbols are there, they become part of the winning combination.

A high volatility math model combines with excellent returns of 96.5% at our picks of the fairest casinos online.

The Tumble mechanism removes all winning symbols, leaving space for those above to drop down. New symbols invade the reels from above and Tumbles repeat until no further win. A multiplier increases by 1x for every tenth winning symbols over a series of Tumbles. Wilds can hold random multipliers of up to 25x and this combines with Tumble values for a potentially huge win from any spin.

If a meteor hits the bottom row, it explodes along with all adjacent symbols, with all those destroyed paying their values.

The Alien Invaders slot machine free spins feature triggers when three or more meteors are in view at once. You get seven spins, plus three more for each additional meteor and unlike on the base games where multipliers reset at the end of Tumbles, during the feature these values only increase.

You’ll always see at least three symbols per reel, which can increase by one at random over Tumbles to a maximum of five. On top of this, wild multipliers can now hit a vast 100x maximum for epic wins.

The Invaders from the Planet Moolah slot by WMS stars cartoon alien cattle, while a wide range of species join forces in the Alien Attack slot machine from Espresso Games.

The unusual way symbols only count when they hit the bottom works well. Play Alien Invaders for free on this page and you’ll soon see how to grab win after win as symbols activate, then explode and new ones drop in. Those wins can add up to 5,000x your bet, or an amazing 1,500,000.00 at the maximum stake, although it’s more likely via the free spins with ever-increasing multipliers throughout.

Join this armada of adorable aliens and enjoy their otherworldly antics as you spin the reels of the Alien Invaders slot machine at the top sites featured right here at VegasSlotsOnline.
