Bonus Features and Mechanics
We designed the bonus mechanics around free spins and money symbols to keep gameplay dynamic without unnecessary complexity. Our system allows up to 20 free spins per round, with retriggers available through collector symbols. These mechanics were balanced to support both casual users and experienced players chasing higher multipliers.
Free Spins and Money Symbols
We added a bonus round where 3, 4, or 5 scatter symbols award 10, 15, or 20 free spins, respectively. All wild symbols that land during this round collect the values from money symbols on the screen. The round includes retriggers and ends automatically if the 2,100× cap is reached.
Every 4 wilds collected retrigger 10 more spins and raise the money multiplier: 2× for the first retrigger, 3× for the second, and 10× for the third. After that, retriggers are disabled, but random fish money symbols may still appear if only one wild is present. We designed this mechanic to keep the bonus round fast and high-paying.
Slot Paytable
We structured the paytable to be easy to follow. Fish symbols carry dynamic money values, while high-paying icons include fishing rods, tackle boxes, and dragonflies. Payouts scale based on your bet size, with combinations starting from three matching symbols on a payline.
| Symbols | Payouts |
 | 5 = £200 4 = £20 3 = £5 |
 | 5 = £100 4 = £15 3 = £3 |
 | 5 = £50 4 = £10 3 = £2 |
 | 5 = £50 4 = £10 3 = £2 |
 | 5 = £20 4 = £5 3 = £1 |
 | 5 = £10 4 = £2,50 3 = £0,50 |
 | 5 = £10 4 = £2,50 3 = £0,50 |
 | 5 = £10 4 = £2,50 3 = £0,50 |
 | 5 = £10 4 = £2,50 3 = £0,50 |
 | 5 = £10 4 = £2,50 3 = £0,50 |
Low-paying symbols are represented by card icons (10–A), with lower multipliers but frequent hits. The wild fisherman only appears during free spins, helping collect money symbols across the reels. This setup makes Big Bass Bonanza UK suitable for players who prefer simple payout logic with a few bonus twists.
