Review of Solar Disc's key features

How to play Solar Disc

When playing the Solar Disc online slot, you will find a great assortment of icons in use. Many of these are themed to complement the game, such as pumas, bears, cups, masks, tokens, and stone keys. To win payouts, you must get three or more matching icons on a payline, starting at the left of the screen.

One of the great features of the game is the wild and Solar Disc icons. The wild is a standard icon and covering all spots on the reels will land a 25,000x payout! The Solar Disc is an important symbol as it will reveal one standard icon that will then turn into a wild. 

The betting options on the game will suit any player and spins can be played for just $0.50. Those that want to bet more to win more can wager up to $500. Bets can be altered at any time and there is an autoplay feature that can also be enabled.

Solar Disc jackpots and bonuses

While there is no Solar Disc jackpot to be won through a progressive network, the base game jackpot is nothing to laugh at, offering a 25,000x payout. In addition to the standard jackpot payout, players will be able to win more by triggering the main bonus round.

This slot features a free spin round where 10 spins are offered. Every spin will contain a Solar Disc, so there are some great chances to create wild combinations for wins. To trigger the bonus, a bonus icon is required along with a Solar Disc. The feature will start automatically and cannot be retriggered.

Solar Disc mobile options

To play Solar Disc mobile, there is no app required, though if your chosen casino has an app, you should be able to access it through this means. The game has been designed using HTML5 technology and can be played using any mobile device via your web browser. The free play demo mode is also available on mobile devices. All of the game features are present and players can easily use the controls to alter bets or select the autoplay feature. The mobile slot loads quickly and operates seamlessly.


When playing Solar Disc from IGT, we enjoyed the great graphics and animations that appeared with every spin, as well as the theme and layout which made it stand out from other titles. We were able to trigger the bonus round a few times and collect profits. The Solar Disc is a nice added feature and can help to boost overall payouts. We reckon any fan of IGT slots will want to take a few real money spins on this game, but why not play the slot for free first?
