Lyngk is game 7 of the Gipf games. It's recognisably part of the same family, but brings its own twist on some familiar mechanics. There are 5 colors, but initially none of the colors are owned by either player. In the course of the game, each player will claim 2 colors; which colors to claim and when to claim them is a key decision. The object of Lyngk is to make "rainbow" stacks of 5 chips with all different colors, topped by a chip whose color you have claimed. The official rules have the details.
