Free-form games are applicable to a range of problem-solving situations. This document discusses gaming as a procedure for organized study of the complex problems entailed in confrontations and crises. The major focus of the booklet is on the various forms of this game type, the kinds of problems to which it is best adapted, and some approaches to its application that have been found to be most useful. It is addressed to individuals and organizations that might consider using free-form gaming as a study technique. Individual sections of the document deal with: (1) an introduction to free-form gaming; (2) the traditional two-playing-teams free-form crisis game (including its uses, structures, required preparation, manning, procedures, post-exercise analysis, and limitations); (3) some suggestions for organizing, conducting, and analyzing free-form seminar games; and (4) variations on the theme (including game purposes, structures, and procedures). A bibliography of 13 references is also included. (TW)
