Selfo is defined as a class of abstract strategy board games subscribed to the category of
connection games. Its name derives from the phenomenon of self-organization (i.e. the
increase in a system’s organization without external guidance), since during the game
the sets of pieces might flow in a coordinated way as they step on the board. Despite its
very simple definition (“group all your pieces by moving in turns to adjacent cells”)
complex self-organization processes takes place under concrete circumstances (a
balanced distribution of pieces and similar levels of expertise in the players), and are the
result of abrupt and deep changes in the tactics. Since a big number of variants have
been found to meet the conditions for self-organization, the particular values given to
the traditional parameters that define a game (i.e., board tiling, size and initial position,
or number of pieces and players) are not so relevant. The Selfo class of connection
games is defined, instead, by the interrelations among parameters in order to favor selforganization.
