Pirate's Treasure Slot by BigPot Gaming

Golden shells drop onto the reels during free spins, and when they do, cannons fire. Each cannon blast converts random positions on that line into Wilds, and if a cannonball hits a spot already holding a golden shell, that shell turns into a 2x multiplier Wild instead of a regular one. Multiple shells in a single free spin round means multiple cannon volleys, so the grid fills with Wilds from directions you can't predict. None of it is player-controlled - the shells appear at random, the cannons target at random, and the multiplier Wilds land wherever the overlap happens to occur. Three scatters award 12 spins, four give 15, five give 20. Buying in skips the scatter wait entirely.

The base game is straightforward. Fifty paylines, a treasure chest Wild that substitutes for everything except the pirate ship scatter, left-to-right only. No random features fire outside the bonus, no multipliers exist in the main game, no retrigger mechanic during free spins either. The cannon is the only thing separating this from a standard payline slot, and it only exists inside the bonus round.

Aged parchment backing behind the reels, golden dagger dividers separating the columns, thick ship ropes and rigging visible above and to the sides. Card values are carved from wood with metal rivets punched through them, and the high-pay symbols - a skeletal captain in a red cape, a brass compass, a red-tipped cannon - all sit in that same warm brown-and-gold palette. The whole thing looks like a pirate deck viewed through a spyglass, which is literally the border element on the left side of the grid.
