Ancient Eclipse: Slot Overview
The tried-and-true Mayan theme returns with a fresh coat of paint in Ancient Eclipse, only the second slot to roll off the Bang Bang Games production line. Their debut title, Wrath of Gods, showed the studio’s fascination with ancient worlds and kind of slipped by unnoticed after launch. Ancient Eclipse should attract more attention thanks to a release via Yggdrasil’s partnership program, which ought to put the developer in front of a broader audience and earn them more visibility with players. Of course, that also raises expectations—so does the team step up?
Beyond borrowing the weight of a major studio name, the team has also built a slot that visually echoes Red Tiger’s modern favourite Gonzo’s Quest Megaways, and to some extent NetEnt’s original too. It’s not so much the mechanics, but the Central American setting and the overall style of the symbols. If you’re on mobile, switching to portrait mode helps you take in more of the vine-covered, temple-packed scenery; on desktop, or in landscape, it doesn’t feel quite as enveloping. The effects are solid and the tribal rhythm thumps along nicely in the background. From an audio-visual standpoint, Ancient Eclipse performs well, even if it can’t fully shake the sense that you’ve been here before.
Set on a 5-reel, 50-payline layout, this Mayan expedition runs smoothly on any device and supports stakes from 20 p/c to $/€100 per spin. Bang Bang Games has shared virtually every stat you could ask for, which is a welcome level of openness. With an RTP value of 96.53% and a hit frequency of 1 in 3.4 spins, the headline numbers look fairly healthy. Players wanting something testing—but not punishing—get medium volatility. One potentially intimidating point is the comparatively high free spins hit rate, which we’d place around Bonanza territory, so don’t expect bonuses to arrive in a constant downpour.
The paytable starts with clubs, diamonds, hearts, spades; followed by three stone sculptures and two higher-value masks. Hit five masks on a payline and you’ll collect 4-5 times the stake. That works out to 250x bet for full-screen hits, which isn’t huge, but it’s at least achievable given how the features interact, and it can be boosted at times via multipliers.
Ancient Eclipse: Slot Features

In both the base game and the bonus, the main objective is to collect Sun Frames in order to place wilds onto the reels. The process is simple: whenever a moon symbol appears, its landing spot is marked with a golden Sun Frame. If a moon symbol later lands in a Sun Framed positions, the Eclipse feature activates. All framed positions are then turned wild for a win evaluation. If multiple triggers occur, the resulting win is multiplied by the number of triggers. In the base game, frames are removed after they’ve been used.
The feathered warrior is the scatter and it can show up on reels 2, 3, and 4. Land 3 anywhere on those reels to trigger the bonus game, which begins with 10 free spins Any frame already present in the base game when free spins are triggered carries into the bonus and locks alongside any new ones. Then, at the start of each free spin, any wild left on the reels from the previous spin locks a Sun Frame on its position. During free spins, Sun Frames remain in place for the duration of the feature. If a moon symbol lands without setting off the Eclipse Feature, you receive one extra free spin.
Ancient Eclipse: Slot Verdict
Bang Bang Games has produced a slot with a mix of strengths and weaknesses, though over time the drawbacks begin to outweigh what it does well. To start with, it’s an attractive game with strong audio and a clear sense of atmosphere—those elements are handled confidently. The feature set sounds promising in theory, but once you’re playing, the pace can start to feel sluggish fairly quickly.
It comes across as though the Eclipse feature consumes a large portion of the RTP, meaning you’re essentially rooting for frames to stack up while you wait for free spins to arrive. And you will be waiting, because they can take a long time to land—390 spins isn’t unheard of, but it’s still a significant stretch, especially if you hit a colder-than-average run. That would be easier to accept if the base game were more engaging. Sun Frames tend to underdeliver, with wins averaging around 30x the bet in testing. Meanwhile, the bankroll kept drifting downward thanks to the clunky payline configuration and generally modest payouts.
By the time free spins finally appeared, it felt like we’d just scaled the tallest step pyramid on earth. With legs on fire, it was time to enjoy the payoff. Unfortunately, the free spins session played out much like the base game. Once it ended, it took real effort to stay engaged and keep spinning. To Ancient Eclipse’s credit, there is solid upside, with a max win of 4,595 times the bet. It also comes with a detailed set of respectable metrics, from potential to hit rate to RTP. Still, those numbers don’t translate particularly well in practice. Somewhere between the concept stage and the moment you press spin, something goes missing, leaving Ancient Eclipse less entertaining than it could have been.
When you compare Ancient Eclipse to the benchmarks in this niche—the Gonzo’s titles and the like—the gap is obvious. The loop feels repetitive, the Eclipse feature often doesn’t make much impact, and the free spins aren’t consistently enjoyable. That doesn’t mean players can’t do well here, but it’s difficult to find many compelling reasons to choose this over other entries in the South American jungle-themed crowd.
