Derivative versions In 1972,
Nintendo introduced a game with a similar timer and shape-fitting mechanic named (タイムショック), which was created by
Gunpei Yokoi and featured a two-tier, circular board with 20 spaces. This variant had a central ring, which could be rotated to change the position of the shapes, adding to the challenge. Another clone, also named
Time Shock, was sold by Sears in 1984; it used a 26-cell board similar to the one described in the 1970 patent and published with the original 1973 release. This version is still sold in Japan as
Time Crash. == Rereleases ==
