The LEGO Znap theme ran from 1998 to 1999 and contained 19 sets. Like the K'nex sets, Znap sets could be used to build frame-like objects using flexible plastic parts with connecting pieces. Some sets featured TECHNIC motors and used colorful connecting parts.

It has been thought that in an attempt to compete with K'nex LEGO introduced the Znap, which was also perceived as a failure.
