Boat Bonanza Down Under is a follow-up game to the earlier Boat Bonanza title developed by Playn Go. This variation ventures into an idyllic Australian beach setting where a laid-back fisherman, who spends most of his time dozing in his lifebuoy, periodically wakes up and catches fish prizes in 3 different ways from the grid below. This game offers a refreshing take on the overcrowded fishing slot genre with its unique gameplay and mechanics.
