What is "yinsh"

YINSH is an abstract strategy board game by game designer Kris Burm. It is the fifth game to be released in the GIPF Project. At the time of its release in 2003, Burm stated that he intended it to be considered as the sixth and last game of the project, and that the game which he had not yet released, PÜNCT, would be logically the fifth game 1. However, an entry in his blog 2 on 19 June 2005 suggests that he is reconsidering this.

Gameplay consists of moving rings to flip Reversi-like discs.
