Connect Four

You 0

Tap a column to drop a red disc.

How to play

  • You drop red discs; the computer drops yellow ones.
  • Tap a column to drop your disc — it falls to the lowest open slot.
  • Line up four of your discs in a row — horizontally, vertically, or diagonally — to win.
  • Choose Easy for a casual game or Hard for a sharper computer opponent.

Strategy & tips

  • Play the centre column early — it is part of the most possible four-in-a-rows.
  • Watch for the computer getting three in a row and block it before it connects the fourth.
  • Set up a "double threat" — two ways to win at once — so a single block cannot stop you.
  • Think about diagonals; they are the easiest wins to miss on both sides.
  • Do not stack straight up unless it helps — you may be handing the square above to your opponent.
