These are the classic bsdgames of old. They've been imported from DragonFly BSD's sources (the games in Dragonfly BSD can be found at http://gitweb.dragonflybsd.org/dragonfly.git/tree/v2.4.0:/games), along with some patches from FreeBSD ports and a couple of games from NetBSD, and only modified enough to get them to build on Mac OS X.
WARNING: These games could conceivably be a security risk (that's the warning I remember seeing with bsdgames in FreeBSD). If this is a concern, don't install them. I am also not responsible if they blow up your computer, lure aliens to your house, run up huge credit card bills, eat your dog, or give you a menacing side-eye. There's also NO WARRANTY, implied or otherwise.
hunt used to use hosts.allow and hosts.deny for access to the huntd server. Mac OS 10.8 "Mountain Lion", however, has dropped tcp_wrappers from the operating system. If you do run hunt on a server connected directly to the Internet, use firewall rules to control who can connect to the huntd server rather than hosts.allow and hosts.deny.
Games included are:

wumpbsdmake is needed to build the games. If needed, you can install it out of homebrew (it doesn't come with recent versions of Xcode).
These games have been built on Mac OS X 10.7 Lion through 10.12 Sierra. They seem to build best with clang - if the compiler complains about redundant declarations, "CC=clang bsdmake" seems to work wonders. Under 10.9 "Mavericks" (or other OS X versions if a newer clang is installed), if the compiler is complaining about "redefinition of typedef 'va_list' is a C11", add CFLAGS="-std=c11" to the build command. With 10.12 Sierra, the "-Wno-nullability-completeness" may be needed, so use CFLAGS="-std=c11 -Wno-nullability-completeness". For me it was defaulting to clang on Mountain Lion, but to gcc on Lion. Other versions of Mac OS X have not been tested - older versions may work, and newer versions may or may not depending on if there have been breaking clang/XCode changes (which happens every couple of OS X releases in my experience). Newer versions get tested when I get around to upgrading one of my Macs.
Installation is pretty basic. The steps are to run "bsdmake", then "sudo bsdmake install", and it will install in /usr/local (or elsewhere, if you edit the Makefile). Homebrew formulae are available in the Homebrew/ directory to make installing bsdgames-osx easier, as well as a more general homebrew tap for some of my programs at https://github.com/ctdk/homebrew-ctdk that includes bsdgames-osx. See BUGS for information for 10.7 users (at least), however.
Currently, to the best of my knowledge, all games are building correctly.
Many of these programs have hard coded paths. Currently all of them are now changed to sensible defaults under /usr/local, but if you want to install somewhere that isn't /usr/local, you'll need to find and update the paths.
morse and piano have been removed because they depend on sound stuff that's not readily available on OS X. dm was removed because, well, no one would want to deal with it anyway.
fortune has been removed because it is readily available elsewhere, and in fact has its own homebrew formula. It's best not to duplicate it here.
If you use the bsdmake in /usr/bin on 10.7 (and probably before), it will try to install as root by default. Either install the bsdmake from homebrew and use the homebrew version (you'll need to directly use the version in /usr/local/Cellar) or set BINOWN, BINGRP, LIBOWN, LIBGRP, etc. to the user and groups you want.
See the COPYRIGHT file & the source for the programs themselves. I claim no authorship of them. Most of the games were imported from Dragonfly BSD, but gomoku, dab, ching, and wtf were from NetBSD.
For lack of a better term. The work porting the bsdgames to OS X was done by me, Jeremy Bingham jbingham@gmail.com.
