Red Herrings is a work of Interactive Fiction written by participants of the 2012 Open Source Bridge Conference during a 1.5 hour collaborative session headed by Bart Massey. Bart subsequently touched it up after playtesting; it is still something of a work-in-progress.
An easy way to try out the game is to visit the playable web page at http://bartmassey.github.com/red-herrings.
