Then we have the Free Spins bonus round. You generally trigger this by landing a specific number of Scatter symbols, which might be a shiny lure or a sunset scene. Reaching this round is like finding a secret hotspot. The Free Spins often feature upgrades, like sticky Wilds, expanding Fisherman symbols, or multipliers that grow with each spin. This setup generates a chain reaction where wins can build on each other, leading to some truly impressive totals.
