Bets span 0.10 to 500 per spin, with vivid fish parts floating into view on each turn.

Respin Feature Explained

Land any rainbow fish segment on the payline to trigger one respin. During the respin, all fish parts match in a single color (purple, green, red, gold, or rainbow), boosting chances for a full matching koi and higher rewards.
