Solar Eclipse Slot Overview
Solar Eclipse is a compact Aztec-themed slot from Endorphina, running on a 3x3 grid with just 5 paylines. Released back in November 2021, it leans into a classic reel setup where the main event revolves around two celestial wilds, the Sun and the Moon, colliding to trigger free spins. If I'm honest with chat, the compact layout gives it a retro feel that won't appeal to everyone used to modern grids. But there's genuine depth hiding behind those three reels.
Symbols and Paytable
Premium symbols include an Aztec chieftain paying x60 for three of a kind, a leopard at x20, and a snake worth x10. Below those sit various gemstones paying between x1 and x4. Not a massive paytable spread, but on a 3-reel game it doesn't need to be.
Two wild symbols drive everything here. The Sun appears exclusively on reel 1; the Moon only on reel 3. Both substitute for all regular symbols. When they land simultaneously, they merge into the Solar Eclipse symbol, which acts as both a scatter trigger and an expanding wild during the bonus round. That mechanic is the entire backbone of the slot.

Free Games with Expanding Symbols
Landing the Sun on reel 1 and Moon on reel 3 at the same time creates the Solar Eclipse symbol and awards 20 Free Games. Before the round begins, a random regular symbol is chosen as the special expanding symbol. If enough of these land anywhere on the grid, they expand vertically to fill their reels and pay across all active lines, even in non-adjacent positions.
Here's where the multipliers come in. When the Solar Eclipse wild covers one full reel, all expanding symbol wins get a x2 multiplier. Cover both reels 1 and 3 with eclipse wilds, and that jumps to x5. On top of that, landing both Sun and Moon again during the round adds 15 more free spins. Decent re-trigger potential for a classic-style slot.
There's also a Bonus Pop feature that lets you buy straight into the free games round. Availability depends on your jurisdiction, so UK players should check whether it's active. A Risk Game sits alongside it too, a card-based gamble where you can double your wins up to 10 times. I'd probably skip the risk game on stream, but the bonus buy could save a lot of dead spins if it's available.

RTP, Volatility and Max Win
RTP sits at 96.04%, which is reasonable for a high-volatility slot. Max win is listed at 4600x your stake. For a 3-reel game that's acceptable, though viewers expecting five-figure multipliers from their bonus rounds will find this underwhelming. Bets run from 0.05 up to 50, so you've got a decent range for streaming at various stakes.
Volatility is officially high according to Endorphina, though one source called it average. From what I can see in the maths, those x2 and x5 multipliers stacked onto expanding symbols during free spins can produce some sharp swings. I'd call it high but not brutal. Sessions will have dry patches, especially with only 5 paylines in the base game.
