How do you play four in a row?

Two players take turns dropping a disc into one of 7 columns; it falls to the lowest empty hole. The first to line up 4 discs of their color across, up or on a diagonal wins, and a full board is a draw. Play the computer on Easy, Medium or Hard, or a friend on the same device.

How to play four in a row

  1. The board has 7 columns and 6 rows. Two players take turns: red and yellow.
  2. Tap a column to drop a disc. It falls to the lowest empty hole of that column.
  3. Make a line of 4 discs of your color: across, up, or on a diagonal. The first line of 4 wins.
  4. When all 42 holes are full and nobody has 4 in a row, the game is a draw.

Play against the computer at Easy, Medium or Hard, or choose 2 players and take turns on one phone or computer. On a keyboard, keys 1 to 7 drop a disc, or move with the arrow keys and press Enter.

Tips to win at four in a row

  • Play the middle column early. It is part of more lines of 4 than any other column.
  • Before each move, check the other player's lines of 3. Block a line that has an open end.
  • Look under your move: a disc there can give the other player the hole they need.
  • Build two threats at once, such as two lines of 3 that need different holes. Only one can be blocked.

Questions

How good is the Hard computer?

It looks 7 moves ahead, plays the middle, blocks your lines of 3 and builds its own. It can still be beaten with a plan of two threats at once. Medium looks 4 moves ahead, and Easy plays at random half the time.

What is the best first move in four in a row?

The middle column. It is part of more lines of 4 than any other column, and the first player who starts there can win with perfect play.

Is four in a row unblocked at school?

It is a normal web page on lifesim.com, with no download and no sign-up, so it opens on most school Chromebooks. We can't promise that every school filter allows it.

Can two people play on one device?

Yes. Choose 2 players: red and yellow take turns on the same phone or computer, and the page keeps the score until you leave. The first move goes to each player in turn.
