This is the 10th year of the fair and it's a major celebration.
Visitors can play with and buy new toys and games before they hit store shelves.
They can also meet some of the people who created them.
"It's really all about play and meeting the inventors," said Mary Couzin. "We have the inventors of Jenga in from the UK."
"I've had three generations of families walk up and treat me like royalty," said Operation inventor John Spinello. "It's very exciting."
The special event includes a young inventor challenge for people between 6-18 to demonstrate games they've created.
The Toy and Game Fair resumes Sunday morning at 10.
