Frequently asked questions
- How do you win Four in a Row?
- Be the first to line up four of your discs in a row — horizontally, vertically, or diagonally. The four connected discs are highlighted when someone wins.
- How smart is the computer?
- The computer takes any winning move it can, blocks your winning move when you have three in a row, and otherwise favors central columns. Thinking a move ahead is the key to beating it.
- Why are center columns better?
- Discs in the middle columns take part in more possible four-in-a-row lines than discs on the edges, so controlling the center gives you more ways to win.
- What if the board fills up?
- If every slot is filled without either side connecting four, the round is a draw. You can start a new game at any time from the button.
