Rock n' Bolt (ロックンボルト) is a puzzle game developed by Activision, released for a number of home computers and consoles including the SG-1000 in 1985. It follows Louie the constructor who must bolt down moving platforms in their correct location within a set time limit.

The SG-1000 port is arguably a better choice over its Commodore 64, MSX and ColecoVision counterparts. This is because it is able to give the game a soundtrack without sacrificing the quality of the graphics. Unfortunately the SG-1000 version was only released in Japan.

Interestingly Rock n' Bolt's cover depicts what appears to be an earlier version of the game, sporting green pieces on a blue background (rather than blue on black) and a more western-looking Louie.
