Follow what happens on the reels from the moment you set your stake to when the round ends.
You choose how much to stake on each spin. Big Bass Bonanza lets you bet from A$0.10 up to A$250. Your bet size changes what you can win: a A$10 stake can return up to A$21,000 if the top prize lands.
Matching symbols form wins across the 10 paylines that run left to right from the leftmost reel. You need at least 3 of the same symbol to land a winning combination. The Lure symbol pays from just 2 matches.
During a base game spin, the reels show standard pay symbols across the 5x3 grid. The Fisherman Wild does not appear in the base game, so you collect payline wins from the other symbols on each spin.
Free Spins begin when 3 or more Scatter symbols land on the reels. You earn 10 free spins for 3 Scatters, 15 for 4, or 20 for 5. The Fisherman Wild becomes active during free spins and collects Money symbol values from the reels.
Before you start playing, you can set a session time reminder through Kinghills Casino. This helps you stay in control of how long you play and keeps your gaming within limits you choose.
You will have seen what the grid looks like during base play and when free spins trigger.
Three or more Scatters land to start your free spins. You receive 10 free spins for three Scatters, 15 for four, or 20 for five. During free spins, the Fisherman Wild appears on all reels and collects Money symbol values. Each fourth Wild collected adds 10 more free spins and escalates the Money multiplier. You can retrigger up to three times, with multipliers climbing to x2, x3, and x10. The bonus round caps at a 2100x win.
In base game mode, the five reels and three rows show standard pay symbols only. The Fisherman Wild does not appear here. Wins form across ten paylines running left to right from the leftmost reel. You spin the reels and match symbols to land wins on these fixed paylines until a Scatter lands.

When the Fisherman Wild lands to start collecting money symbols depends on chance alone. You might trigger free spins quickly or play many rounds without reaching the bonus.
Big Bass Bonanza returns 96.71% over time, but one session can give you much more or much less. The RTP describes long-term play across many spins, never what happens to you today.
The top prize of A$525,000 exists in the game, but reaching it happens extremely rarely. Most sessions end far below the maximum possible win.
These games range from 96.50% to 96.52% RTP and from x5 000 to x25 000 maximum win across release years 2025 and 2026.
