Apollo Stacks slot review

Take a spin with the God of the Sun in this Greek mythology-inspired choice of slots from developer AGS. With five reels, four rows and 50 paylines, this video slot holds the potential for a free spins bonus that can retrigger and jackpot prizes that could appear at any time. With an RTP of 95.99 percent, read on to find out more in our Apollo Stacks slot review. 

Shoot for the sun

The world of Olympian deities is always a reliable source for slots themes, as these mythological figures have provided inspiration for countless works of art across history. In the Apollo Stacks slot, we see the God of the Sun and Archery, Apollo, towering above the reels and possibly taking up a little too much of the screen. 

Design and layout

One major criticism of this slot is the amount of space devoted to the reels, as opposed to the jackpot prizes and Apollo himself. While it certainly keeps your eyes on the prize, it makes it harder to follow the symbols on the reels where the action is happening. 

Soundtrack and sound effects

This AGS free slot goes for an old-fashioned feel by providing no soundtrack as such to accompany the reels. It utilizes beeps and rings that evoke the clatter of land-based slots as opposed to some of the sleeker and cinematic contemporary slots. 

Apollo Stacks RTP & volatility 

AGS has given this title an RTP of 95.99 percent, placing it just a fraction below the average of 96 percent we recommend when comparing slots at online casinos. Of course, as with any RTP, this is a long-term prediction of its payout potential. Individual games can vary greatly.

Volatility

Testing this slot in demo mode suggests a medium level of volatility, with a small number of low wins appearing with some frequency and the potential for larger wins accompanying the jackpot prizes and bonus features.

How to win at Apollo Stacks

There are 50 paylines in this title, on which you will need to match at least three symbols starting from the left reel to land a win. Your total win will be the highest match on each line added together according to the win multiplier values in the paytable. 

Betting options

Bets are offered in a range from 0.60 to 30.00, which isn’t the hugest spread out there but should suit most casual players. 

Max win 

The max win is the grand jackpot. When playing with the lowest bet of 0.60, it will award 1,000.00. This is achieved by making all reels gold, as explained in the bonuses below.

Apollo Stacks bonuses 

The Apollo Stacks bonus features are various and enhance the base game of this otherwise old-school slot:

Wilds

Wilds will substitute for winning symbols, apart from the bonus or scatter symbol, to help you form winning combinations. They also offer the highest wins for symbol matches and appear with gold backgrounds that potentially help to trigger the jackpot prizes.

Stacked Apollo

The second highest-paying symbol is Apollo, who always appears stacked across three symbol spaces on a reel. 

Free spins bonus

The sun symbol is the scatter symbol, only appearing on reels one, three and five. It will trigger the free spins bonus, in which you have a choice of spins:

  • 15 free spins and wilds on reels 1-2
  • 10 free spins and wilds on reels 1-3
  • 6 free spins and wilds on reels 1-4

Jackpot prizes

The jackpots are triggered by completely covering the corresponding reels with gold backgrounds as listed next to their values. Any symbol can appear with a gold background, while wilds will always have gold backgrounds. 

At any time, the fifth reel may feature the title Apollo Stacks symbol, which will expand any gold backgrounds already on the reels to cover the entire reel. This greatly improves your chance of accessing one of the jackpots.

Apollo Stacks review: our verdict 

Although it is a struggle to see the reels, as Apollo himself is occupying so much of the display, this is an otherwise decent slots title with a good range of bonuses and a satisfying theme. Just remember to zoom the screen in demo play.

FAQs

How do you win the jackpot prizes in the Apollo Stacks slot?

You need to cover at least reels one and two with gold backgrounds to win a mini jackpot prize. Reels one to three award the minor jackpot, reels one to four the major jackpot, and reels one to five award the grand jackpot. Any symbol can appear with a gold background at random, while wilds will always have gold backgrounds. The Apollo Stacks symbol that only appears on reel five will expand any background to cover the reel if you are lucky enough to land it.

How many free spins can be won in the Apollo Stacks slot?

First, you will need to land three of the scatter symbol, which is the sun in this Apollo-themed game. You will then be presented with a choice of three bonuses, with either 15, 10 or 6 free spins on offer. These come with wilds on reels one to two, one to three, and one to four respectively. This means you have a choice between increasing your jackpot chances and a greater number of free spins.
