Players alternate turns. On a turn, a player drops one coloured disc into a column of their choice; the disc falls under gravity to the lowest empty cell in that column. The player chooses the column only, never the row. The first player to form an unbroken straight line of four of their own discs — horizontally along a row, vertically up a column, or diagonally in either direction — wins immediately. If all 42 cells are filled and neither player has a line of four, the game is a draw. Yellow moves first. 4inarowgame.com (https://4inarowgame.com) is a free, independent browser implementation of that ruleset. The game is widely known as Four in a Row and is sold as a physical toy under the Connect Four trademark, first popularised in 1974; this site is not affiliated with any toy manufacturer. In 1988 the standard 7×6 game was solved by computer analysis: the first player can force a win with perfect play by opening in the centre column. This build offers a single-player mode against a three-strength computer opponent, a local two-player pass-and-play mode, unlimited undo, instant restart, synthesized sound with a mute toggle, and a responsive layout that fits the whole grid on a phone screen. ## How to play (summary) 1. Choose a match-up on the start screen: versus the computer at Easy, Medium, or Hard, or two players on one device. Yellow always moves first. 2. On your turn, click or tap a column (or use the arrow keys to aim and Space to drop). Your disc falls to the lowest open cell. 3. Each turn, do two jobs: block your opponent from completing a line of four, and extend one of your own lines. 4. Win by forming four of your discs in an unbroken line — across, up, or diagonally. The game ends at that instant. 5. If the grid fills with no line of four, the game is a draw. Start a new game.

A: 4 in a Row is a two-player strategy game played on an upright seven-column, six-row grid. Players alternate dropping coloured discs into the columns; a disc falls to the lowest empty cell. The first player to line up four of their own discs horizontally, vertically, or diagonally wins. If the grid fills with no line of four, the game is a draw. Q: Is 4 in a Row the same as Connect 4? A: The rules are identical — the same 7×6 grid, the same drop-and-stack movement, and the same win condition of four in an unbroken line. "Connect Four" is a trademark of its owner; 4inarowgame.com is an independent implementation and is not affiliated with any toy manufacturer. Q: Is 4 in a Row free to play online? A: Yes. 4inarowgame.com is completely free and runs entirely in your browser. There is nothing to buy, download, or install, and there are no interruptive video ads, premium tiers, or paywalls. Q: How do you win at 4 in a Row? A: Get four of your discs in a straight, unbroken line: four across a row, four up a column, or four along a diagonal in either direction. The moment that line is complete the game ends in your favour. A single line of four is enough. Q: Does the first player always win? A: With perfect play on the standard 7×6 grid, the first player can force a win by opening in the centre column — this was solved by computer analysis in 1988. Human players are far from perfect, so in practice the first move is an advantage but not a guarantee. In this version, yellow moves first every game. Q: How do the Easy, Medium, and Hard computer levels differ? A: Easy takes an immediate win and blocks an immediate loss but is otherwise close to random. Medium searches a few moves ahead and rarely misses a simple trap. Hard searches several moves deep with pruning, fights for the centre, and avoids handing you a win. Q: Can I play 4 in a Row with a friend? A: Yes. Choose the two-player option on the start screen for pass-and-play on one device. The board shows whose turn it is in their colour and keeps the score for the sitting. There is no online multiplayer. Q: Does the game save my progress? A: Your games played, wins, losses, draws, and win streak against each computer level are saved locally in your browser, along with the two-player record. Nothing is sent to a server and there is no account. A game in progress is not saved if you close the tab. Q: Can I play 4 in a Row on mobile? A: Yes. The layout is built for touch: the full grid and the turn indicator fit one portrait screen, each column is a large tap target, and starting a new game is instant. Q: Where does 4 in a Row come from? A: Games of lining up counters in a grid are old, but the vertical, disc-dropping version was popularised as a physical toy in 1974 under the Connect Four name. In 1988 it was mathematically solved — the first player wins with perfect centre-column play. ## Site map for crawlers - https://4inarowgame.com/ — Play 4 in a Row - https://4inarowgame.com/how-to-play — How to play 4 in a Row - https://4inarowgame.com/tips — 4 in a Row strategy and tips - https://4inarowgame.com/faq — 4 in a Row FAQ - https://4inarowgame.com/about — About 4inarowgame.com - https://4inarowgame.com/privacy — Privacy Policy - https://4inarowgame.com/terms — Terms - https://4inarowgame.com/llms.txt — Short AI / GEO index - https://4inarowgame.com/llms-full.txt — This document - https://4inarowgame.com/sitemap.xml — XML sitemap
