Connect Four

Connect Four is a classic two-player strategy game where opponents take turns dropping colored discs into a vertical grid. The objective is to connect four of your discs in a row, either horizontally, vertically, or diagonally, before your opponent does the same. The game was first published by Milton Bradley (now Hasbro) in 1974 and has since become one of the most popular family strategy games in the world. Despite its simple rules, Connect Four has been mathematically solved, with the first player able to force a win with perfect play. This means every game presents a genuine strategic challenge where the right moves can guarantee victory.

1. The board is a vertical 7-column, 6-row grid. Players choose a color (usually red and yellow).
2. Players alternate turns dropping one disc into any column that is not full.
3. Discs fall to the lowest available position in the chosen column due to gravity.
4. The first player to connect four discs in a horizontal, vertical, or diagonal line wins.
5. If the board fills completely without either player connecting four, the game is a draw.
6. Think ahead and try to set up positions where you can win in multiple ways.

• Players alternate turns, dropping one disc per turn
• Discs always fall to the lowest available row in the chosen column
• Connect four discs of your color in any direction to win (horizontal, vertical, or diagonal)
• The game is a draw if all 42 spaces are filled without a winner
• A column that is full cannot accept more discs
• The first player has a strategic advantage and can force a win with perfect play

• Control the center column. The center column is involved in more potential four-in-a-row combinations than any edge column.
• Build threats in multiple directions. A position that threatens to connect four both horizontally and diagonally forces your opponent to block one, letting you win with the other.
• Watch for diagonal threats. They are the hardest to spot and the most common way to win against casual players.
• Do not blindly block every opponent threat. Sometimes letting them build in one area while you create a winning position elsewhere is the better strategy.
• Control the lower rows first. Discs need support below them, so building a strong foundation limits your opponent's options.
• Look two or three moves ahead. The key to winning is setting up unavoidable double threats.

• Standard Connect Four (7x6): The classic game on a 7-column, 6-row grid. The original and most popular version.
• Connect Five (10x8): Requires five in a row on a larger 10-column, 8-row grid. Increases the strategic complexity significantly with more space and longer winning lines.
• Pop Out: Adds the ability to pop a disc out from the bottom of a column, shifting all discs above it down. Adds a new tactical dimension.

• Simple rules that anyone can learn in 30 seconds
• Deep strategic gameplay despite its simplicity
• Quick games lasting just 5 to 10 minutes
• Satisfying to outthink your opponent with a clever double threat
• Perfect for all ages, from children to adults
