Use your rod to aim for the hook on the ducks' heads as they float around the tank. Lift them out of the tank and drop them into the barrel to score points and move onto the next level.
While playing, keep an eye out for the lucky sailor ducks - they'll give you double points if you can hook them in time. But watch out for the sneaky pirate ducks, they'll steal your points if you hook them from the tank!
Between rounds you'll get the chance to boost your score in the Fair Game Duck Shoot. Hit as many targets as you can, but remember you're against the clock!
