The objective of the game is to get the most lives by the end of the game. Lives are a set of exactly four stones of the same color in a row either, horizontally, vertically, or diagonally. If a set of four stones in a row increases to five or more stones, the life is removed. The game is over when all spots on the board are completely filled with stones or if the last player opts to not place a stone on the board.
Open up index.html, and click on an empty spot on the board. The score is shown to the top left under the game title, while the reset button is shown on the top right under the game title. The left score is the number of white stone lives, while the number on the right is the number of black stone lives. The reset button will refresh the page so that you can play a new game.
