Four in a Row is the classic connect four strategy game brought to life in a bright, polished browser experience. The rules are simple: drop your colored disc into a 7-column grid and be the first player to line up four in a row — vertically, horizontally, or diagonally — before your opponent does. Every move matters, and one wrong drop can flip the whole game.

The game offers two solid modes: face off against the computer across multiple difficulty levels, or go head-to-head with a friend in local 2-player mode on the same screen. The AI gets genuinely tricky on harder settings, forcing you to think two or three moves ahead rather than just reacting. Blocking your opponent while setting up your own winning line is the core skill here, and it never gets old. The clean visual style and satisfying sound effects keep each session feeling snappy.

Four in a Row is a perfect pick for kids, families, and anyone who enjoys classic board game puzzles without the setup. Whether you're searching for a free connect four game online, a no-download puzzle game for two players, or a quick brain game to sharpen your strategy skills, this one delivers every time. It runs smoothly on any device through your browser, so there's nothing to install — just pick a color and start dropping.
