Ancient Eclipse draws its imagery from Mayan celestial mythology, built by Bang Bang Games and distributed through Yggdrasil's network. The setting is all carved stone temples, golden accents and sacred iconography, played out across a 5-reel, 4-row grid with 50 fixed paylines, where wins land whenever three or more matching symbols appear from left to right starting on reel one.
The mechanic driving everything is built around Sun Frames. Whenever a Moon symbol lands on the grid, it leaves behind a golden outline — a Sun Frame — on that position. The real payoff comes when a second Moon symbol lands somewhere that already carries a Sun Frame: that triggers the Eclipse Feature, turning every framed position into a wild symbol simultaneously, with a multiplier attached that scales up based on how many wilds get created in that single conversion. It's a genuinely patient mechanic — frames accumulate quietly across spins, and the pay-off depends on how many you've built up before the eclipse actually fires, which gives the base game a real sense of anticipation rather than a flat, repetitive rhythm.
That same Sun Frame system carries into the bonus round. Landing three scatter symbols, styled as a blue-feathered warrior, on reels two, three and four awards ten free spins, and crucially any Sun Frames accumulated during the base game carry over into the feature rather than resetting, giving players who've been building frames before the trigger a genuine head start. New wilds created during the free spins stick in place as well, letting the multiplier potential keep compounding across the round.
Numerically, Ancient Eclipse runs a 96.53% RTP, comfortably above the industry average, paired with high volatility — appropriate for a mechanic built around occasional big multiplier conversions rather than constant small wins. The confirmed maximum win sits at 4,595x the stake, and betting ranges from 0.20 up to 100 per spin, giving reasonable flexibility for different bankroll sizes.
What sets this version of Ancient Eclipse apart is really the patience built into the Sun Frame system — it rewards players who stick around long enough to watch frames accumulate rather than expecting an eclipse on every spin. Between the Mayan temple presentation, the carry-over mechanic into free spins, and a solidly above-average RTP, it's a well-constructed high-volatility pick.
