Hexxagon for

From Foursquare Development:

Hexxagon is an implementation of the classic puzzle game which is a variant of the "Othello" game - also known as "Ataxx", "Hexxagon" and "Infection" originally created by Dave Crummack and Craig Galley, for the Palm Computing Platform.

Hexxagon is a variation of the popular board game Othello, where the aim of the game is to fill the board with as many pieces that belong to you as possible. The board is hexagonal in size, with each piece on the board having up to six neighboring pieces. Moving a piece over one space (to neighbor) creates a new piece (a duplicate), while moving over two spaces physically moves the piece.
