About Connect 4

Connect 4 is the classic vertical strategy game. Take turns dropping red and yellow discs into a seven-column grid, and be the first to line up four of your own colour across, down or diagonally. Play a best-of-three match against the computer on Easy, Medium, Hard or Expert, or challenge a friend on the same device.

Tips

Control the centre column: it is part of the most possible fours.
Look for threats on every move, yours and your opponent's.
Build two threats at once so your opponent can only block one.
Don't play directly under a square your opponent needs.

Connect 4 is free to play on GameChakra. It works in any modern browser on mobile, tablet and desktop, with no download or sign-up. Your scores, XP and achievements are saved automatically on your device.
