About this game
Overview
Connect Four is a classic disc-dropping duel: line up four of your pieces before your opponent does. Play against a strong computer opponent, or challenge a friend on the same device. Turns are simple—pick a column, drop a disc, and let gravity stack your plan—but the board fills quickly with forks, blocks, and diagonal threats. A clear-rules browser warm-up for short rounds and light mind games.
Tips
- Watch diagonals as closely as rows and columns—many surprise wins hide there.
- Block your opponent’s three-in-a-row immediately.
- Against the AI, avoid leaving double threats; it punishes slow or greedy attacks.
- Control the center columns early so you have more ways to build four-in-a-row.
FAQ
- Can two people play together?
- Yes. Pick local two-player, then take turns on the same device. The second player drops discs on their turn the same way.
- Is there online multiplayer?
- No. You play against the computer or a friend on the same device in your browser.
