Skull Coins Slot by Amigo Gaming

Gold coins spill across the floor of a ship's hold, heaped around a treasure chest tucked to the left of a compact 3x3 grid. Dragon gargoyles carved into stone archways loom on either side, and the reels sit inside a dark wood border with skulls mounted at each corner. Deep blues and purples dominate the background, cut through by warm gold on the coins and the ornate metallic lettering on the card symbols. It's a pirate setup, but darker and more cramped than most - a vault, not an open sea.

The PIN WIN bonus triggers when three or more coin symbols land on a single spin. Triggering coins slide off the reels and into a collection area, and the round plays out as a series of respins where new coins keep dropping in. Gold coins carry fixed values. Red coins are accumulators - they don't hold their own value but instead scoop up the totals from every gold coin currently visible and add them together into one payout. So the order matters. A red coin appearing after five gold coins have already stuck pays out the combined sum of all five. That collector mechanic is what separates this from a standard hold-and-win loop where each coin just sits with its own number.

Four jackpot tiers run down the left edge of the screen: ULTRA (1,000x), MAX (150x), MID (50x), and MIN (25x). All four are available during the PIN WIN round, and their EUR values scale directly with bet size - at 0.05, ULTRA shows 50.00. No buy bonus, no ante bet, no free spins toggle. The game funnels everything through that single bonus trigger on a tiny grid with only five paylines, which means base game spins resolve fast and coin landings come down to frequency on a small surface. Three coins out of nine positions is a third of the grid, simple enough on the surface, but the accumulator interaction with jackpot tiers is where the 2,500x ceiling actually lives.
