In addition to wilds and the symbol expansion feature that help create winning combinations, you have the chance to land golden reels to unlock one of four incredible progressive jackpots. Trigger the mini jackpot with two gold reels or turn all reels gold to claim the grand jackpot prize.

If you’re a fan of AGS land-based casino games, the online Apollo Stacks slot is a perfect choice for you.

Action-Packed Myth-Themed Slots from AGS

Apollo Stacks is a sleek online adaptation from the U.S. software giant, AGS. As a major developer of slot machines and casino games in the United States, AGS has transformed many of its popular titles for online play.

When you engage with the Apollo Stacks slot machine, you’ll enjoy all the familiar land-based excitement typical of AGS slots, on both desktop and mobile devices. No download is required; simply launch the game in your browser and start spinning.

The layout of Apollo Stacks is user-friendly, with the reels situated at the bottom of the screen, and the top left area reserved for the display of the four progressive jackpots.

The Apollo Stacks slot machine embodies a strong Greek mythology theme. The formidable god Apollo oversees the reels as you play. Standard low-paying symbols are depicted as traditional royals, with a five-of-a-kind combination paying out 50-60 coins. Keep an eye out for other iconic symbols from Greek mythology, such as Perseus’s shield and sword, and the legendary flying horse Pegasus.

Enjoy 50 Paylines with Bets up to 600 Coins per Spin

The Apollo Stacks online slot features a 5×4 reel grid and offers 50 paylines. You can adjust your bet size starting from just 0.01, with the option to wager between 60 and 600 coins on each spin.

Apollo Stacks is accessible for play at top legal online casinos. This game is considered highly volatile, yet the 95.99% RTP is likely to attract many players.

The wild symbol substitutes for all symbols except scatters, and when included in a winning combo, it rewards a payout equivalent to that of two matching symbols on the reels. Apollo can also appear in stacked form, where even the lower half of Apollo can stand in for the upper half, resulting in a corresponding payout.

Choose Your Free Spins

One of the features of the Apollo Stacks slot machine is the opportunity to win free spins. To trigger this round, land three sun symbols on reels one, three, and five.

Upon activation, you’ll have the chance to select your free spins option. Opt for 15 free games with two gold reels, 10 spins with three gold reels, or six free games with four gold reels.

Keep an eye out for the Apollo Stacks symbol, which appears on reel five and triggers an expansion of any gold symbols present on the screen. This expansion causes the gold symbols to fill the entire reel, enhancing your chances of hitting the progressive jackpots.

Trigger a Progressive Jackpot Win with the Gold Reels

Apollo, the God of the Sun, wielded a golden bow capable of bestowing health and power. In Apollo Stacks, this bow can also lead you to a lucrative jackpot.

The gold reels play a crucial role in the Apollo Stacks slot machine. During any base spin, reels one to four have the potential to turn gold.

You’ll secure the mini jackpot when reels one and two are entirely covered in gold backgrounds. Achieve the minor jackpot by turning reels one, two, and three gold, and secure the grand jackpot by turning all reels from one to four gold.

If all five reels turn gold, you’ll claim the massive grand jackpot. To be eligible for the grand jackpot, play with the maximum coin stake.
