📖 Detailed Explanation
In the base game of Fire in the Hole 3, a collapse in the Collapsing Mine mechanic is triggered by four main events, expanding the grid from 3 to up to 6 active rows with each occurrence.
- Winning combination: Matching 3 or more symbols from left to right pays out, removes the winning symbols, and triggers symbols to fall downward, allowing new ones to drop in from above.
- xBomb Wild explosion: This wild substitutes for any symbol except scatters. It explodes to remove adjacent symbols (except scatters), increases the win multiplier by +1, and triggers a collapse—whether part of a win or not (if no win or Wild Mining occurs).
- Wild Mining feature: Activates when 3 to 6 identical symbols align horizontally or vertically without a win, xBomb, or xHole. The symbols are removed, replaced by 1-4 wilds in the center (1 for 3 symbols, up to 4 for 6), and positions above explode (except scatters and ice-buried symbols), causing a collapse and revealing buried features.
- xHole feature: The xHole pulls in adjacent paying symbols, scatters them back as split symbols (size 1-3), then disappears, triggering a collapse. Wins are paid before this; multiple xHoles increase split sizes.
Each collapse pays wins first, removes symbols, and drops new ones, potentially chaining reactions up to 46,656 ways to win. Ice-buried symbols (hiding wilds, multipliers, etc.) may unlock during these, adding excitement without direct collapse triggers. This mechanic, core to Nolimit City's design, builds on prior titles for dynamic base gameplay.
