Panther Moon Slot by Playtech

Everything here runs off the glowing-eyed black panther. It stands in for every symbol except the full moon, and any winning line it completes pays double. Drop two panthers into the same combination and that doubling chains rather than adds, so the line runs x2, then x4. The panther is also the top payer on the board, and five of them along a line is the heaviest single hit the game offers. No separate multiplier feature sits behind it. The wild does that job by itself.

The full moon over a moonlit lake is the scatter, and it pays from wherever it lands instead of along a line. Two of them already return double your total stake. Three or more award 15 free spins, and this is where the maths gets loud. Every win in the round is tripled, and the panther's doubling still stacks on top, so a single wild line during the feature runs at x6, with chained panthers pushing it higher again. The round retriggers with no cap, so a run of moons can stretch it well past the opening 15.

The setting is a tropical jungle after dark, the reels sitting near-black against a purple-and-magenta twilight with silhouetted palm fronds and vines hanging into the corners. Night creatures fill the symbols: a white barn owl glowing in a green halo, a jackal howling up at a blood-red moon, an iridescent green dragonfly, a red carnivorous flower and a blue water lotus, with ornate silver Celtic-style royals down the low end. It's an old Playtech build and plays like one, no buy option and no jackpot, just the doubling wild feeding those tripled free spins.
