Gold of Mermaid Slot by Amigo Gaming

Eight free spins with the entire low-pay tier stripped from the reels. Three golden shell scatters on the middle columns open a round where only the octopus, jellyfish, turtle, and nautilus remain - no card symbols at all. The paytable shrinks, the average hit jumps, and retriggering with three more scatters adds another batch. Stacked wilds still appear during these spins, capable of filling an entire column with substitutes across nothing but high-value icons.

Pin Win runs parallel to everything else. Six or more pearls on a single spin lock into place, each showing a bet multiplier - 0.10x, 0.25x, 1.50x, values in that range. Three respins start the countdown, and any new pearl resets it back to three. But the pearls aren't the only thing landing in this round. Treasure chests show up unannounced, cracking open to reveal mystery prizes including Minor, Major, and Grand jackpot payouts. All three tiers are progressive, tied to bet level and server accumulation, so the actual numbers shift. Pin Win can fire from the base game or mid-free-spins, which means the stripped paytable round and the hold-and-respin round occasionally collide in the same bonus chain.

Deep blue water fills every inch of the background, coral branches and kelp rising along the edges, schools of small fish drifting past. The symbols sit against dark navy reel strips inside a heavy golden border - the octopus is a vivid red with curled tentacles, the jellyfish glows translucent purple, and the turtle is rendered in clean emerald green against its own framed tile. Card symbols (A, K, Q, J) are styled with gold filigree that fits the underwater treasure motif without looking generic.

No buy bonus option. Scatters restricted to reels 2, 3, and 4 means you need all three middle columns to cooperate for free games - reel 1 and reel 5 never contribute to the trigger. The stacked wilds compensate somewhat in the base game, covering full reels and bridging gaps across the 25 paylines, but triggering either bonus still depends on specific symbol density in specific positions.
