PanLink is an open source clone of the puzzle game LinLink. You have to pair up pictures following rules similar to Mahjong.

PanLink was forked from llk_linux in January 2013, which seems to be abandoned since 2005. First release is v2.4 and based on the 2.3beta1 source code of llk_linux. Major changes are optimizations for fitting the OpenPandora screen, stripping and rewriting some incompatible or deprecated code and replacing artwork with unclear licensing.
