IGT took the idea of special symbols that change others into wilds – and made a spectacular and atmospheric game from it. The Solar Disc online slot features wildlife, along with tribal masks and items associated with ancient native civilizations. Unique music with prominent drumming plays while you spin. Hit the special symbols and they explode – producing stunning shockwaves of light.
Stacked symbols give you a shot at covering the reels in winning combinations. When more than one of the special symbols land, whole reels can turn wild. The bigger reel grid lets you combine multiple five-of-a-kind wins. Solar Disc symbols do appear in the base game. When you trigger the free spins, they are guaranteed to hit on every spin. Get more than one, and you could see the ‘mega win’ coin show while your prizes are counted.
You can enjoy Solar Disc slots online or in live casinos across Canada. This is one of many IGT slots which have a loyal following. You will find this game in both large and mid-sized venues. Check it out the next time you visit the Grand Villa Casino in Edmonton or the Northern Lights Casino in SK.
For online players, you can find this game at Stars Casino, DraftKings Casino and Caesars Online Casino in Canada.
What will you play next?
Solar Disc slot machine: Transforming symbols feature
When you hit the spin button, streaks of golden light will zoom past at random. These are special symbols, which show an elaborate pattern of concentric designs, like a native tribal take on the sun. They can appear on any reel, and as you will see – the more you get the better.
Each time one lands it will start to glow. It then flips, revealing one of the regular symbols. Next, it explodes with bright light covering the reels. Any matching symbols are now turned into wild symbols. If you get more than one, the process repeats until all the discs have exploded.
With stacked symbols in play, randomly selecting the right symbols can cover all of the reels in wilds – or (more frequently) connect multiple win-lines.
Free spins with guaranteed transforming symbols
Only one special bonus symbol appears on the reel of Solar Disc slots online. This says ‘bonus’ and appears on reel 1. When you get one, the other reels get highlighted in turn, and spin for longer. To trigger the free spins feature, you need to combine this bonus symbol with one or more transform symbols.
Only having one bonus symbol has a hidden advantage. Unlike on other slots, the bonus triggers are less likely to work as blockers for your regular line wins on those spins where they did not trigger special features.
You get ten free spins, with a significant boost. At least one of the transform symbols will appear on every spin. If you are lucky this can be combined with spins where you get two or three of them.
Setup and winning symbols on Solar Disc slots
You spin this slot for 50 coins – with the minimum bet at 50c for most Canadian casinos. Bets can be increased by adding multipliers or raising your denomination. There are twenty-six win-lines, crossing a standard 5×4 square grid of the reels. Your biggest wins will come on those spins where you cover the entire grid in the special wilds via the transforming symbols. That will get you an incredible 25,000 coins.
Regular symbols are headed by detailed wild animals. There is a cougar and bear sharing the top spot. There are only four more symbols. These are a vase, mask, key, and engraved stone. Having a smaller number of symbols is an advantage. When you hit two or more transform symbols, your chance of connecting big wins is higher when there are fewer different symbols on the reels.
If you are playing online, there is an auto-play option. I found this was slow compared to other IGT slots. The solar disc takes a long time to scroll through the different winning combinations after each spin.
Solar Disc slots online: Native gold design
This is a beautifully produced game. It has distinctive graphics, and intensive electronic music combined with pseudo-native pulsing drums. There are no filler symbols like playing cards or gems – setting Solar Disc apart from other IGT titles.
Behind the reels, you will see glimpses of a stone temple, with a mountain range in the background. Gold coins are strewn on the floor in the foreground. The detail of the wild animal symbols on the reels is excellent. They have short animations when you win with them. The noteworthy animations happen when you get the Solar Disc transforming symbols. They explode, turning other symbols wild in blazing light. The explosive sound effects are worth hearing too.

Wrapping up: How do Solar Disc slots compare?
Casino games giant IGT are known for their innovative gameplay. Solar Disc added a wow factor for design on top of the transforming symbols system. Turning all of one or more symbols wild is boosted by the fact that there are only six regular symbols in play. If you get more than one transforming symbol, then you could easily be looking at covering up to half of the reels in wild symbols. When you get to the free spins bonus, guaranteed transforms can make for a hugely profitable feature. They do happen in the base game, though less frequently.
