Solar Eclipse Slot by Endorphina

Sun on Reel 1. Moon on Reel 3.

Most slots with a trigger mechanic ask you to land 3+ scatters anywhere. Solar Eclipse narrows the condition: the Sun wild appears exclusively on reel 1, the Moon exclusively on reel 3. Both on the same spin merge into the Solar Eclipse symbol and start 20 free games. Neither does anything on its own to trigger the feature - you need the alignment.

The Aztec setting earns its theme. Stone temple architecture frames the 3x3 grid, the background shifts through deep orange and gold tones, and the symbol set mixes Mesoamerican wildlife - jaguar, cobra - with gem icons in blue, green, pink, and purple. Compact and clean. No clutter.

Free Games: Expanding Symbol + Eclipse Multiplier

Two mechanics run in parallel during the 20 free spins. First, a symbol is selected at random to gain expanding capacity - when enough copies land on the reels, they expand vertically and pay across both adjacent and non-adjacent positions. On a 5-payline grid, that second part matters: normal play requires left-to-right sequences, but expanded symbols bypass that restriction.

Second, the Solar Eclipse wild stays active on reels 1 and/or 3. A 2x multiplier applies when it covers one reel. Fill both reels 1 and 3 simultaneously and the multiplier jumps to 5x - and triggers 15 additional free games. So the retrigger condition and the peak multiplier are the same event.

Bonus Pop: Paying for Your Expanding Symbol

The Bonus Pop button purchases the free games round directly. The distinctive part is the symbol selection: rather than a random expanding symbol, you pick. Seven options, seven prices based on potential return. The Emerald gem - lowest-paying regular symbol - costs 91x your bet. The Jaguar runs 169x. The top-paying Aztec Chief is 271.5x. You're buying both the feature and the variance within it.

Bonus Pop is subject to jurisdiction and casino settings. Some operators disable it entirely.

Risk Game and Some Honest Observations

Any win can be taken to the Risk Game - a card-comparison round where beating the dealer's card doubles the payout, up to 10 consecutive times. Jackpot wins and Bonus Pop winnings are excluded from the gamble.

The 3x3 format and 5 paylines make the base game thin between bonus triggers. Spins resolve fast: win or no win, minimal buildup. The expanding symbol during free games is random unless you use Bonus Pop, so the same round can pay very differently depending on which symbol gets selected. That gap between a low-value gem expanding versus the Chief expanding is significant at 5x multiplier.
