Four in a Row
Board
Four in a Row is a free connect-four style strategy game against an AI with three difficulty levels, from casual to expert. Drop your discs, build threats in two directions at once, and block your opponent before they block you. Quick matches, deep tactics, and a ladder mode to prove your mastery.

Click or tap a column to drop your disc; it falls to the lowest empty slot. Connect four of your discs in a line — horizontal, vertical, or diagonal — before the AI does. The column preview shows where your piece will land before you commit.
Tips & tricks
Take the center column when you can: it touches the most winning lines. Build double threats — two ways to win at once — because a single threat is always blocked. Watch the diagonals; they are the lines human eyes and easy AIs miss first.
