About This Game
Play Connect Four solo against AI, with a friend on one device, or online against anyone! Online mode gives you a 4-digit code to share — your friend enters it and you're connected instantly.
Players take turns dropping colored discs into a 7-column, 6-row grid. The first to connect four discs in a row — horizontally, vertically, or diagonally — wins!

No worries — if you switch away, your opponent waits up to 5 minutes. Come back and the game resumes exactly where you left off.
What's the difference between AI difficulty levels?
Easy is great for beginners. Medium offers a fair challenge. Hard uses advanced minimax algorithm and is really tough to beat!
