To free players from jail, a rescuer must tag the jailed player. There are several variations of darebase that hinge on different rules for freeing captured players from jail. In one variation, only one person can be freed at a time: whichever player has been in jail the longest. In this variation, the most recently captured player joins the line at the point of the jail while the players that have been in jail the longer move towards the other end of the line. The most senior prisoner must be tagged in order to be freed.
