Zombies At The Door

Embark on a spooky adventure, but beware of the undead creatures as they are coming to get you! In fact, they are at the door!

Gold fever has awakened the ancient miners from their deadly slumber, and they are sneaking towards you in the quest for some stunning prizes across the 5 reels. Defeat them, and the maximum winning potential of 5500x the stake could be yours!

The devs at Peter and Sons decided to put you in front of the potential future where zombies rule the world but help you with some innovative special features, such as Increasing Panels during Free Spins!

Theme and Symbols

One thing is sure, for starters, this zombie-themed online game comes with superb graphics across a big game area.

The action takes place in some kind of a room, showing a wall in the background decorated in beautiful blue wallpapers with dark blue leaves, with shelves hooked to the wall featuring different jars on the right, and three toilet paper rolls and an old radio on the left.

The window barricaded with wooden boards represents the reel set, lit by a lantern, and thanks to them, the whole scene looks like the zombie apocalypse is coming. Besides, you can see zombies sneaking behind, approaching the door.

On them, you will find nicely-created icons showing playing card symbols from 10 to A, as well as a variety of characters, such as an old bearded man, a young girl, a police officer, and a man carrying a munition, while...

...the yellow Zombie warning sign is the Wild, and the bullets and the green creature represent the Scatter symbols.

The overall atmosphere is complemented by an animated character carrying a backpack standing to the left and a spooky soundtrack and sound effects following the action.

Betting Options and Other Functions

Zombies at the Door is equipped with 5 reels and 3 rows while offering 20 ways to win but are subject to change during the Free Spins round.

Before you start playing, you will need to set your bet level, and you have the ability to wager for a minimum of just $0.20 on a spin to $40.

The theoretical return to player for this medium-volatile online release is 96.3%, while all wins are paid left to right, except scatter that pays in any way.

Playing card symbols 10 and J are the lowest-paying symbols, rewarding up to 4x your stake for 5 in a combo, followed by the rest of the card symbols while...

...five characters are the high-paying symbols, with the man carrying a munitionpaying the most – 1x, 6x, or 30x the stake for 3, 4, or 5 of a kind.

Not only does the Wild symbol substitute for all other regular symbols, but it also pays the same as the most-valuable character!

Special Features

When it comes to bonus features, everything in this online game revolves around two Free Spins rounds with increasing panels!

But, before we mention them, another quick hit feature triggers whenever a green monster Scatter appears on the last reel. When that occurs, it will award a win on all high-rewarding symbols!

Now, pay attention to the Scatter bullets as by collecting five of them in a progress bar, you will trigger the Free Spins round that awards 10 extra spins!

But, here's the kicker!

When that happens, you get to spin those bonus spins across the 5x4 panel while using 40 pay lines!

Wait, there's more!

Collect another five Scatters during the feature, and you will trigger the Super Free Spins feature that gives another 10 extra spins and a 5x5 panel with 60 ways to win!

Not bad at all!
