The Sentinel, released in the United States as The Sentry, is a puzzle video game created by Geoff Crammond, published by Firebird in 1986 for the BBC Micro. It was converted to the Commodore 64, Amstrad CPC, ZX Spectrum, Atari ST, Amiga, and IBM PC compatibles. The Sentinel was among the first games to use solid-filled 3D graphics on home computers. It won numerous awards upon release and has since appeared on several "best video games of all time" lists.
