One part of Aztec civilization that is often overlooked is its wealth and magic. This IGT’s Solar Disc slot online design addresses this issue, taking you back in time to long-forgotten treasure tunnels believed to be lost forever.
You are not just a spectator in this immersive world and may claim precious artifacts and jewels for yourself. These ancient objects are worth thousands of dollars in contemporary times and are surprisingly easy to find.
Popular among players in Australia and New Zealand, the treasure hunt mostly takes place in the golden grid, which houses precious artifacts, including goblets, gold coins, tribal masks and keys to treasure vaults. Will you succeed in your mission to claim these valuable treasures? It is not an impossible goal, and there is the magical solar disc symbol to guide you to glory. Another two mystical characters are within reach, helping you achieve immortality. So, the odds are in your favor.
IGT put the work into Solar Disc slot online graphic and design. The 6×4 grid has a golden frame with a tribal styling that makes it look like a fortune mirror in some way. There is a lot going on in the background, which paints the picture of a desert suffering from the aftereffects of a volcano eruption. The entire blend of the screen gives a feeling of chaos and suspense with unknown potential.
Intuitive icons are strategically placed at different positions on the grid. On the Right of the grid are the Circular Arrow spin icon and AutoPlay menus. The former allows you to spin the reel manually, while the latter lets you set multiple spins at a go. At the left of the grid is a ‘>’ menu that takes you straight to the wager window for placing bets. Once you set your preferred stake, the changes instantly reflect on the ’Total Bet’ and ’Balance’ menus at the grid’s bottom.
Check the top-right corner of the screen to access the Paytable, Game Rules and Audio windows. These pages show you how the symbols pay and all the necessary conditions you need to satisfy to win. Of course, we explained all of these in this review. So you don’t have to worry about deciphering them yourself.
The animation and audio effects for this slot are impressive. A light piano tone comes to life with every spin. Also, different effects, ranging from fire to colors lines, appear on the reels as you spin the grid. Whenever you land wins, relevant symbols dance on the grid, almost ready to jump off and join in your celebrations.
Following its successful launch in the USA, the Solar Disc casino game has 26 unique paylines and 9 symbols. Only 6 of these symbols are regulars that form wins on paylines. The others are bonus characters, including a wild, a Bonus inscription and a solar disc. We talk about all three characters in the next section. For now, we turn our attention to the 6 regulars.
All 6 regulars trigger wins by forming a 3-of-a-kind to 6-of-a-kind combination, courtesy of the game having 6 reels. The symbols are expressed in coins, a common feature for IGT designs. To place a bet, head to the betting window and determine your coin value. The system automatically converts the coins to its dollar equivalent.
See the table below to know how each symbol pays when they land on any of the 28 paylines.
| Symbols | 6 of a kind | 5 of a kind | 4 of a kind | 3 of a kind |
| Puma | 250 | 75 | 30 | 15 |
| Bear | 250 | 75 | 30 | 15 |
| Goblet | 75 | 30 | 20 | 10 |
| Mask | 75 | 30 | 20 | 10 |
| Key | 50 | 20 | 10 | 5 |
| Coin | 50 | 20 | 10 | 5 |
The three bonus characters play an integral role in activating Solar Disc casino game bonuses. Put on your seat belt as we take you on a ride into Solar Disc features.
Wild and Pattern Win: The Wild is the gold carving with Wild inscription. It has the ability to substitute the 6 regular symbols and complete wins. However, it cannot do the same for the other two bonus characters. It is possible to land Wild in all positions of the grid, courtesy of the solar disc symbol. If this happens, then you have a Pattern Win, which pays 25000, the highest single payout possible in this machine.
Solar Disc Symbol and Solar Disc Feature: The solar disc is the gold circular plate shaped like the sun. This symbol randomly appears on the reels and changes to one of the 6 regular characters. That character and others like it on the grid automatically turn to wild, significantly increasing your chances of landing payouts. This phenomenon is the Solar Disc feature.
Multiple solar disc symbols may appear on the reels simultaneously and reveal different regular characters. Similarly, these characters and their look-alikes automatically become wilds and may create an avalanche of wins. It is possible to score a pattern win this way, as we mentioned before. A symbol can only be turned into a wild one time. If a new Solar Disc appears on the reels will change to one of the unpicked regulars. If all regulars have been transformed, then new Solar Disc characters on the reel naturally turn to wilds.
Free Spins Bonus: Look out for the flat Bonus symbol which occasionally appears on the reels. If this symbol appears in reel one and the solar disc character shows up in any of the other reels, they will combine to trigger 10 free spins. The FS game is quite massive because every spin guarantees a solar disc appearance.
Betting on a Solar Disc casino game is quite the experience because its default currency is coins. To stake, you need to register with a quality platform like FreeSlots99 and launch the title. Head to the Bet window using the relevant menu on the left side of the grid.
The Bet window has three dedicated sections. The first highlights the number ‘50’. This is the fixed number of coins that you must cover per bet. You cannot increase or decrease this value. The second section focuses on the coin size, which you may adjust with the – and + buttons. A coin may range from $0.01 to $10. The last section confirms your bet value in dollars. Once you choose a coin size, the system automatically multiplies it with the 50 fixed coins to determine your bet value in dollars.
With the smallest coin size set at $0.01 and coins per wager fixed at 50, the minimum possible bet you can place is $0.50. Also, the maximum wager possible is $500.
Spin the reels after placing your wager and form wins. Earned payouts reflect on the reels and add up to your real money balance. Note that your chance of earning a payout does not depend on previous spins. Each spin result is independent of the other. So, you may earn wins with as many spins if you are lucky enough. As well, this title only pays for the highest number of a kind in any single payline. It is possible to trigger more than a single payout on the grid if you are lucky enough to land matching combinations in different paylines.
The RTP for a Solar Disc casino game is 96.01%. This value is in line with the 96% industry average, which is good news. Theoretically, a 96.01% means that a little above 96% of players’ bets are paid back to them as winnings, while casinos keep 3.99% as profits.
We should emphasize that this expected RTP payback is based on theory and, statistically, the general expectation over a long period. However, during real play, players may experience unique outcomes. Some may enjoy over 300% return on their sessions, while others may hit better even better percentages. Basically, the result of each spin is based on randomness and your bet size in part. Usually, the bigger your bet size, the better your chances of activating this slot’s best features.
Solar Disc has a medium volatility, which explains its good payout frequency. Yeah, we quickly picked on the fact that the title pays 1.6 times out of 4 spins, which is a relatively good return. Also, the payouts are quite sizable, giving players a real chance to earn profits in the short and long term.
Alright, we have to clear it up. This slot does not have a jackpot. Don’t worry, though, as you won’t miss it. There are many ways to earn big time. The Pattern Win, for example, pays extremely well and is just as good as any sizable jackpot. You can earn a whopping 250000 coins, which translates to thousands of dollars on a sizable bet.
Also, maximizing the free spins feature does increase your chance of earning substantial payouts. Realistically, you stand a chance of winning thousands of dollars if the features and spin sequence are favorable. From experience, you are odds on to enjoy at least one favorable sequence within 60 spins.
Solar Disc slot online theoretical limit is $25,000,000. This value is common with many IGT games and is the provider’s way of saying there is really no max limit to worry about. Realistically, you are more likely to hit hundreds and thousands of dollars a million times before you get a 7 figure win. So it is really important that you keep your objective and aim realistic.
While well-known for their Nomadic lifestyle, the Aztec population is not often credited for their ingenuity in wealth creation. IGT’s Solar Disc corrects this misconception, taking players to buried caves and tunnels filled with fortunes and history. There are multiple rewarding symbols and unique bonus features to maximize along the way. The graphics and design are also excellent and immersive, drawing you into the magic of early Mexico.
