About the game

Bass Boss is a 2022 fishing-themed slot from Red Tiger where Fish symbols can land anywhere and carry instant-win prizes based on stake multipliers. The Bass Boss above the reels randomly drops his hook to collect every Fish on a chosen row, while Contest Spin symbols launch a bonus round of Free Spins with a catch counter that adds extra spins and float multiplier boosts. The Improved Bait feature can also attach multipliers to the float in the base game, upgrading any Fish it catches. If you enjoy this blend of line wins, catch mechanics and progress bar bonuses, you can explore other similar games in our demo hub.
