Want to feel like a kid again? Bridgton will host the Four Square World Championships Saturday, and the playful competition is open to the public.

Four square is the classic schoolyard kickball game in which a square court is divided into four sections. Each player takes a square and must defend it from other players.

More than 100 people are expected to participate in the world championships, which will be held at 5:15 p.m. at Bridgton Academy in North Bridgton. Entrants will be divided into two women’s and men’s divisions. There will also be a competition for children.

The Four Square World Championships are organized by Peter Lowell, a longtime four square fan who works for the Lakes Environmental Association. The $10 registration fee at the event will go toward the work of the environmental group.

Officials from Square Four will oversee the event.

There is no advance registration required, but to help with planning competitors should email Lowell at lakes@leamaine.org.
