Solar Disc

Solar Disc is a thrilling new online slot from IGT that’s based on the Aztec god of the sun, war, and human sacrifice, Huitzilopochtli. The graphics are dazzling as is the gameplay, and to offer something different to your typical online slot, the game’s creators have used six reels and twenty-six paylines.

Due to the increased winning potential that’s on offer, Solar Disc costs a little bit more to play than average. The minimum bet is 50p, and high rollers can enjoy playing with stakes of up to £500 per spin. And, should you need any further convincing to take it for a spin, there’s the top jackpot of 25,000 coins!

As you explore the mysterious landscape before you, revelling in the sight of the famous Aztec temples, you have the opportunity to earn generous prizes through a plethora of ancient artefacts and animal symbols. There’s a wild symbol that can assist you in creating wins, as well as a bonus symbol that can grant access to the Free Spins Feature.

But, what’s really unusual about the Solar Disc online slot is its unique, self-titled scatter symbol which can appear on any of the six reels, and transform into a randomly-chosen paytable symbol which then turns all of the same symbols that are currently showing on the reels into wilds.


Solar Disc dazzles you with its richly coloured graphics. Underneath your feet, there are piles of glittering golden coins while ahead of you, there are mountains, terraces cut into the hillside, and an Aztec temple climbing up into the sky. The view is made even more beautiful by the purple-and-pink sunset that bathes the land beneath it in vivid lilac and peach hues.

The reel set looks particularly impressive as it consists of six reels rather than just five. Plus, there’s an extra row of symbols, which means that you get twenty-four symbols on the reels on every spin.

The delicately illustrated symbols in the Solar Disc online slot include gem-encrusted goblets, colourful carvings of ancient deities, gold coins, bronze keys, metal shields, leopards, and bears.

There is a total of twenty-six paylines and the number of active paylines cannot be altered. To create wins, at least three matching symbols must appear on a played line and on consecutive reels, starting with Reel 1.

You get access to all twenty-six paylines for fifty coins, but you can adjust the size of your bet using the on-screen arrows. Once you’re ready to begin, simply click the circular arrow to confirm your stake and spin the reels.

The Auto Spin Feature is optional, and it plays the game automatically for a given number of spins at your chosen bet size. You can also set loss limits and single win limits.

At the top-right of the game screen, there are three buttons which let you view the paytable and the game rules, as well as turn the audio on and off. The paytable is where you’ll find the cash values for the different winning combinations that can be made along with details of how the two bonus features work.

Wild Symbol

The wild symbol in this beautifully crafted IGT online slot is the gold carved stone marked “WILD”. It can contribute towards winning combinations by replacing all other symbols in the game with the exception on the bonus and scatter symbols.

The wild symbol also has the potential to grant Pattern Wins. A pattern win occurs when every position on all six reels is filled with wild symbols, which secures you the top jackpot of twenty-five thousand coins.

Scatter Symbol

The scatter symbol in Solar Disc is the red, gold and blue “BONUS” symbol, and with the assistance of the bonus symbol, it can unlock the Free Spins Bonus. The scatter can only appear on the first reel in the base game, and it pays out in its own right as a paytable symbol.

Bonus Round

There are two special features in this IGT online slot, both of which are totally engaging.

The red-and-gold shield which acts as the scatter symbol triggers the unique Solar Disc feature whenever it appears on the reel set. Each shield reveals a randomly-chosen symbol that turns all matching symbols into wilds. And, as multiple scatters can appear on the screen on the same spin, there’s plenty of potential to score super-sized prizes.

The second special feature of this game is the Free Spins Bonus. It’s triggered when the “BONUS” symbol appears on the first reel at the same time that a scatter is in view. You gain ten free games, but the best bit is that the scattered shield is present on every free spin and, therefore, increases the chances of the Solar Disc feature being awarded. Furthermore, the Free Spins Bonus uses riches reels than the base game, so there are more opportunities than normal to create valuable winning combinations.
