Tic Tac Toe: 4 in a Row

A vertical drop changes the usual tic-tac-toe routine. In a match of Tic Tac Toe: 4 in a Row, X and O pieces fall into a standing grid and settle only in the lowest empty cell or directly above another mark. Four matching symbols in a horizontal line, a vertical stack, or a diagonal wins the round. Solo play pairs you with a bot. Local two-player mode shares the same screen with a friend. Grid options include 6x7, 7x8, 7x9, and 7x10, and board size doesn't alter the challenge setting.

How to play?

Drop a mark into an empty column and claim space before the opposing symbol connects four. Alternate moves under the classic back-and-forth rhythm, reading the position after each piece lands. Build a row across, pile four upward, or thread a diagonal through the stack. Block the next line when the rival symbol lines up first. Pick solo or local multiplayer, then choose one of the available grid sizes and begin the round.
