The playing board of Fargpass consists of a 5x5 grid.During the first phase of the game, the players take turns filling the grid with black and white chits, one in each space except one.In the second phase, the players take turns placing another type of chit that has a 1x2 shape, and that has two colored dots on it: white-white, white-black or black-black. Each chit must be placed so that it corresponds to the chits placed during the first phase.The first player that can't legally place a chit in the second phase loses. - BoardGameGeek
