SameGame was originally created as Chain Shot! in 1985 by Kuniaki Moribe. It was distributed for Fujitsu's FM-8 and FM-7 platforms in a Japanese monthly personal computer magazine called Gekkan ASCII. In 1992, the game was ported as SameGame to Unix platforms by Eiji Fukumoto, to the NEC PC-9801 series by Wataru Yoshioka, and to Macintosh as ChainShot! by Eiichiro Mawatari. In 1993, it was ported to Windows 3.1 by Ikuo Hirohata. This version was translated into English by Hitoshi Ozawa, and is still available from his software archive.
In 1994, Takahiro Sumiya ported it to Macintosh. This version has some gameplay differences—a choice of between two and five colors—and is probably the most widely distributed of the original series. It was the basis for the Same Gnome and KSame variations created for Linux.
In 2001, Biedl et al. proved that deciding the solvability (whether all blocks can be removed) of 1-column (or 1-row) 2-colour Clickomania can be done in linear time. Deciding the solvability of 2-column, 5-colour Clickomania is NP-Complete. Deciding the solvability of 5-column 3-colour Clickomania is also NP-Complete.
