This Chrome extension is intended for people who want to play Connect Four without having to open the browser app or visit the official website. Connect Four can be played with one of two players. In one player mode, the board is fully visible and there is no need to minimize the browser. In the other mode, the board is minimized and is not visible unless the user opens the game. The board is split into nine sections, six in the upper half and three in the lower half. The game begins when both players place their first piece. After placing a piece, a player can place a maximum of four consecutive pieces in a row, or in a column, or diagonally.
