Overview
Big Bass Bonanza is a video slot from Pragmatic Play released in 2020, kicking off an entire series of fishing-themed games. Unlike the provider's later hits (Sweet Bonanza, Gates of Olympus), it uses classic fixed 10 paylines on a 5x3 grid rather than a Pay Anywhere system.

Game mechanics
The base game runs on 10 paylines - rare but steady wins accompany the wait for the bonus. Money Fish symbols carry a random cash value, which is only activated if 'caught' by the Fisherman Wild during free spins - in the base game they don't pay out on their own.
Bonus and free spins
Free spins trigger with 3, 4 or 5 scatter symbols (fishing boat), awarding 10, 15 or 20 free spins respectively. During the bonus, the Fisherman Wild collects the values of all visible Money Fish symbols on the grid. Every 4 caught Wilds extends the round and adds a random multiplier (2x, 3x or 10x) to the collected total.
