Gold of Sirens Bonus Buy Slot by Evoplay

Two bonus paths run in parallel here, and they don't interact with each other at all. Free spins use a Wild Replace system - at the start of each spin, the game picks one of the four low-pay symbol types and turns every instance of it into Wild for that single spin. The selection changes each spin, so some rounds flood the grid with Wilds while others barely shift anything. Three Scatters trigger 8 spins, four give 10, five give 12, and landing additional Scatters during the round adds one spin each. Separately, the Hold & Win jackpot game fires when six or more jackpot symbols land on a base spin. Three respins, each new symbol resets the counter, and regular jackpot symbols carry random values from 1x to 10x bet. Minor is a flat 20x, Major 50x. Fill all 15 positions for the Epic at 3,000x.

The base version requires natural triggers for both features. This Bonus Buy edition adds a four-option shop: 8, 10, or 12 free spins for 40x, 50x, or 60x total bet. The fourth option - a direct jackpot game entry at 34x - is actually the cheapest in the store. One respin round with jackpot symbols already seeded onto the grid, skipping the base game requirement of landing six organically. The free spins buys follow a straightforward price-per-spin ratio, but that 34x jackpot shortcut is what separates this version from the original.

Deep teal water fills the background behind a sunken stone temple. Two siren figures flank the reels, tails wrapping along the columns. Siren portraits in red and green hair make up the high pays, with translucent purple jellyfish, golden shells, and crimson hermit crabs below them. Three jackpot meters sit above the grid - Major in red, Epic in gold, Minor in green. Coral clusters and underwater rock formations line the base of the reels, and a Poseidon figure with a golden trident watches from behind the grid.
