Play Connect Four

Drop a disc, block the computer, connect four. The classic 7×6 gravity game against a beatable AI or a friend.

The job

Connect Four is deeper than it looks — center control wins games. This version plays it straight: gravity, 7×6, first to four.

Play

Pick computer or two players, click a column to drop. The AI wins when it can, blocks when it must, and prefers the center — solid but deliberately beatable.

  • Building from the center outward creates more threats than edge play.
  • Watch for traps: a move that gives you three also gives the opponent a drop above it.

Worked example

Playing columns 3-4-3 early claims the center pair; two stacked threats in column 3 force the defender to answer one and lose to the other.

Where it stops

One board size, one AI level — no lookahead depth setting, no game history, no network play. Scores reset when you leave; nothing is stored.
