Gipf for One

Gipf for One is a freeware, open-source adaptation of Kris Burm's abstract board game from 1997, the first of a series of six games sharing similar concepts created by the same Belgian designer. Two players take turns placing black and white pieces on a hexagonal grid, where the main objective is to remove the adversary pieces out of the board by lining up four pieces in a row. New pieces are added from the starting points dotting the edge of the playing field, and pushed in moving the whole line forward. Pieces of either color are continuously reused by both players until one of the them is unable to add new ones to the board. The game can be played against computer or human opponents, in one of three variations with an optional timed mode.
