Both Crowther's and Woods's version were designed to run on the PDP-10 and used features unique to [[Fortran#FORTRAN_IV|DECSYSTEMS-10 Fortran IV]] on that architecture, meaning that the program could not be easily moved to other systems, even those that could run Fortran programs. One of the first efforts to [[porting|port]] the code to other languages or systems was by [[RAND Corporation]] researcher [[James Gillogly]] in 1977. Gillogly, with agreement from Crowther and Woods, spent several weeks porting the code to the [[C (programming language)|C programming language]] to run on the more generic [[Unix]] architecture.<ref name="Electracity97"/> It can still be found as part of the [[Berkeley Software Distribution|BSD]] Operating Systems distributions, or as part of the "bsdgames" package under most [[Linux]] distributions, under the command name "adventure".<ref name="BSDadventure"/> Bob Supnik of [[Digital Equipment Corporation]] also ported the game in Fortran to the [[PDP-11]] minicomputer in mid-1977, spreading it to other minicomputer systems.<ref name="GetLampSupnik"/> Afterwards, numerous other ports were made of the game to different languages and systems, sometimes identified by the number of points available in the game.<ref name="RaymondHistory"/> There were enough ports and variants and alternate takes of the game by 1982 that an article in ''[[Your Computer (British magazine)|Your Computer]]'' described the entire set of games wherein the player enters short commands to move between set locations as "''Adventure'' games", and provided code for the [[ZX81]] computer for an "Adventure-writing kit" program that could be used to generate a game with that gameplay.<ref name="ZX81writingkit"/> In 2017, [[Eric S. Raymond]] created a port for modern computers of Woods's 1995 version of the game as ''Open Adventure'' and released the source code under an [[open-source license]] with permission from Crowther and Woods.<ref name="RaymondHistory"/><ref name="OpenAdventure"/>

Commercial versions of the game were also released. [[Microsoft]] published a version titled ''[[Microsoft Adventure]]'' in 1979 for the [[Apple II Plus]] and [[TRS-80]] computers, and again in 1981 for [[MS-DOS]] as a launch title for [[IBM Personal Computer|IBM PC]]s, one of the few software programs and the only game at launch.<ref name="BYTE79"/><ref name="BYTEIBM"/> [[The Software Toolworks]] released ''The Original Adventure'' for IBM PCs in 1981; endorsed by Crowther and Woods in exchange for a nominal payment, it was the only version for which they received any money.<ref name="bilofsky"/> [[Level 9 Computing]] released multiple versions of the game for different computer platforms under the name ''[[Colossal Adventure]]'', beginning with a version in 1982 for the [[Nascom (computer kit)|Nascom]] that includes an entire extra section where the player saves elves from flooding caves, as well as later versions that include pictures of the areas.<ref name="ColossalAdventure"/>

A 3D remake of the game, under the title ''Colossal Cave'', was released by Cygnus Entertainment as its first title in on January 19, 2023, for [[Microsoft Windows|Windows]], [[macOS]], [[Linux]], [[Nintendo Switch]], [[PlayStation 5]], [[Xbox Series X]], and [[Meta Quest 2]].<ref name="3DAdventure"/> Designed by [[Ken Williams (game developer)|Ken]] and [[Roberta Williams]], co-founders of [[Sierra Entertainment]], the game was started as a hobby project by the pair during the [[COVID-19]] pandemic, before being expanded into a full commercial product by a team of thirty.<ref name="PSRemake"/> It was intended by lead designer Roberta to be a recreation of how playing the game felt like to her in 1979.<ref name="ViceRemake"/>
