More than 25,000 people are expected to visit the 10th annual Chicago Toy and Game Fair (ChiTAG) at Navy Pier today and tomorrow to check out the newest and best toys and games for the holiday season.

The best thing about the Chicago event, the largest of its kind in the nation, is that kids and adults are welcome, even encouraged, to try out the goods and participate in a myriad of games and activities.

Mary Couzin, founder and CEO of the Chicago Toy & Game Group, which hosts the fair, calls it a “giant interactive and bottomless toy box.”
