Build Your Brain as You Form These Intriguing Architectural Puzzles

They look simple enough, but these surprisingly challenging puzzles are not unlike the challenges architects face when solving structural issues. Curious Cross can be built with just three pieces. Can you figure out how? Third Dimension is a brain teasing 3D puzzle of 18 pieces. Only one piece, however, is the "lock" that holds the beautiful puzzle together.

Ages 5 and up.
