knexK’nex announced exciting changes for its 14th annual K’nexpert Search, which launched on May 29. The K’nexpert Search challenges young builders to design and submit a creative, original model made entirely from K’nex parts. The models are judged on creativity, uniqueness, and detail.

For the first time since its launch in 2001, the contest will have four grand-prize winners from four different age groups. Age groups include: 5 to 6 years, 7 to 8 years, 9 to 11 years, and 12 to 14 years (a new category this year). The four imaginative children who win will each receive a prize package valued at $3,650. This year, grand prize winners will receive the coolest K’nexpert prize package yet: $2,500, an iPad Mini, a $250 gift card to Toys “R” Us, and a $500 K’nex credit code good toward a shopping spree at An additional eight finalists will each receive a $250 K’nex credit code, a $100 Toys “R” Us gift card, and a K’nex T-shirt.

The K’nexpert Search runs through August 23, with winners announced in October. Children can enter using the online entry form found on the K’nex website. Submissions must include three photos of the creation, and a one-minute video or one-page summary describing how the child came up with the idea, how long the design took to build, and how many K’nex pieces were used. For more information, view the official rules here.

A panel of judges comprised of K’nex employees will select semi-finalists; an online vote will determine 12 winners and Joe Smith, senior vice president of development at K’nex, will choose the four grand-prize winners.

The K’nexpert Search is open to all U.S. residents, excluding those in Maine, and no purchase is necessary.
