There's plenty of exciting gameplay ahead when you choose to play the Wild Worlds slot game from NetEnt at Quartz Casino! Wild Worlds is a mobile-friendly title that uses Avalanche Reels to give you the best chances of winning generous cash prizes worth up to 2,500 times your stake.

The Wild Worlds slot is made by the same software developer (NetEnt) as some of our most popular games, including Twin Spin, Starburst, and Gonzo's Quest, and you can play it with stakes as small as 20p and as much as £100.

Our Verdict:

We're one of the first online casinos to confess our love for NetEnt, but even the well-known software developer has excelled itself with its Wild Worlds slot.

The game borrows a popular special feature called Avalanche Reels from a couple of other NetEnt titles and adds to it with exciting and new innovations called the Destroy Feature and Hero Wilds.

The result is Wild Worlds – a thrilling, sci-fi themed game in which you must help the lead characters prevent aliens from taking over Planet Earth.


Thanks to the excellent design of the Wild Worlds slot game, you feel as though you're in the heart of the action, inside a spaceship that's being pilot by three brave birds. As electronic music and swooshing, sound effects are played, you move closer towards one of the major cities on Earth to take on a group of alien invaders.

On the right-hand side of the screen, you'll see the playing area which is made up of a five-by-five grid which contains a colourful assortment of pink, green, and blue symbols, each of which is linked to one of the three birds.

At the bottom of the reels, you have plus and minus buttons next to both "Level" and "Coin Value" which let you increase and decrease the total stake size according to your budget and preference. The "I" icon brings up the rules and paytable while the Auto-Play button lets you set the game up so that it can automatically spin the reels a specific number of times.

Wild Symbol:

The flashing "W" symbol is the Wild Worlds wild symbol, and it can increase the likelihood of creating winning combinations by replacing any symbol apart from the scatter.

Bonus Features:

The Avalanche Reels feature can bring you great rewards in Wild Worlds as it allows you to form wins in a row using three or more matching symbols before removing all winning symbols from the playing area to give you more chances to win with the symbols that replace them.

As the game also relies on the Cluster Pays game mechanic, you can form wins in any direction provided that the symbols lie adjacently next to each other.

There are also two special features that can help you out along the way. Hero Wilds can be awarded when a winning combo is formed from Hero symbols, and it turns all of the medium-value symbols into wilds. Destroy picks one of the three birds (blue, pink or red) at random and removes all symbols that do not match the chosen colour from the reels.

In the Free Spins Bonus of the Wild Worlds slot, you gain eight free games and the chance to work your way through multiple levels where Heavy Wilds, Spreading Wilds, and Random Wilds are up for grabs.
