Respins feature

Feature

The game checks the collection at the end of the spin. A triggered Respins round starts with 5 respins on a 5x5 grid.

The marked collection zone starts at 2x2 and moves after each respin. It collects Coin and Lightning Money values that land inside it, including triggering Lightning values already on screen.

Collected Lightning Money symbols expand the zone and add respins at the stated thresholds. The round ends when no respins remain, with possible modifiers affecting reels and how the win is awarded.
