Here’s how to play the IKEA Renton River Days Duck Hunt III, leading up to the festival at Liberty Park July 27-29.

Once again, 30 ducks are scattered around Renton for this year’s mystery duck hunt, officially called Duck Hunt III: A Case of Fowl Play. Doctor Ducky has been duck-napped and the goal is to figure out how to pay his ransom.

The hunt requires a game card, available at any location where a duck is hosted or online at the Renton River Days website and the Renton Reporter website. The clues to find the ducks also are posted on the festival’s Duck Hunt page and a trentonreporter.com.

Find a duck and get the game card stamped at each location. A completed game card will help players figure out how to pay the ransom for Doctor Ducky at the festival. The more ducks you find in the hunt, the greater the chance of winning prizes at the Renton River Days.

The duck hunt ends on July 25. Rentonreporter.com is serializing the clues, with a new one posted each day.

Complete details are on the game card.

Here’s the clue for Ellery.

A duck’s beak is called a bill. Ellery goes to this City Hall Department to take care of hers.
