+Connect Four is a two-player connection board game. It is also known as Connect 4, Four Up, Plot Four, Find Four, Captain's Mistress, Four in a Row, Drop Four, and Gravitrips in the former Soviet Union.
+
+Players choose a colour and then take turns dropping coloured tokens into a seven-column, six-row, vertically suspended grid. The pieces fall straight down, occupying the lowest available space within the column.
+
+The game's objective is to be the first to form a horizontal, vertical, or diagonal line of four of one's own tokens. Connect Four is a solved game. The first player can always win by playing the right moves. Connect Four is a two-player game with perfect information for both sides, meaning that nothing is hidden from anyone. Connect Four also belongs to an adversarial, zero-sum game classification since a player's advantage is an opponent's disadvantage.
