About game
Insert colored discs into one of the seven columns. Be the first to line up four discs in a row — horizontally, vertically, or diagonally — to beat your opponent. Challenge a formidable AI that anticipates every move, or compete against a friend in local two-player mode. Choose between light and dark themes, use the undo button, and enjoy the game without downloads, ready to play on any device.
How to play
Select a column with a click or tap, then release your disk into the bottom-most open slot.
Reset the game: clear the board and begin a new round right away.
Change the theme: switch between light and dark modes in the settings.
