Each Fishing Duels board contains a maximum of 81 cells. Each cell may contain a fish or some other object. The player who first collects the required number of fish is the winner.
Fish can be collected by switching and matching 3 or more of them horizontally or vertically. A number of fishing items such as floating markers, hooks, rods, wormbaits and basket traps can be collected as well, while they are used to get you in-game power ups.
