Ecuador Gold Slot by ELK Studios

Ghosting Wild is the mechanic that defines the base game. It lands on the inner four columns, then drifts a random number of positions across the grid, converting every cell it passes through into a wild. When it crosses one of the oversized symbols (2x2 Super, 3x3 Mega, or 4x4 Epic blocks), the entire block turns wild. One activation can leave three or four wilds scattered across the board. During free drops, those wilds become sticky and stay locked for every remaining drop, so early Ghosting Wild trails build a permanent foundation that later drops inherit.

Symbols appear in those four size tiers, and the bigger ones interact with the avalanche expansion in a specific way. The grid starts at 4 rows. Each winning cascade adds a row, up to 8 rows total. Bigger grid means more vertical room for Epic and Mega blocks to physically fit. A 4x4 Epic symbol needs at least 4 rows of clearance, so it barely squeezes onto the starting grid but has room to spare at 7 or 8 rows. Two Epics on a fully expanded board create way-win density that the base layout can not produce. The free drops bonus has a Safety Level system tied to this: each winning drop during the bonus raises the minimum row count by one, and it never drops back down. Win three drops in a row and every subsequent drop starts at 7 rows regardless of whether new cascades push it further.

Three scatters award 10 free drops, four give 15, five give 20, six give 25. No buy-in option exists, so the bonus triggers organically or not at all. The Gold series grew into eleven games after this one, from Voodoo Gold through Elysian Gold, and each successor raised the win ceiling and added mechanics. But the expanding grid, big symbols, Ghosting Wild, and Safety Level all started here. Stone-carved Aztec walls, burning torches flanking the reels, serpent masks on the premium symbols. The template aged better than the math.
