Connect Four, also known as Four in a Row, is a classic two-player strategy board game with simple rules that are quick to learn yet offer deep strategic complexity.
I. Game Components
- Board: A standard vertical grid measuring 7 columns × 6 rows, for a total of 42 spaces.
- Pieces: Each player uses one color—typically red and yellow—with 21 pieces per color.
II. Basic Rules
- Placement Method
- Players take turns, dropping one piece at a time from the top of the board into any column.
- The piece falls under gravity to the lowest available space in that column.
- Once a column is filled with six pieces, no more can be dropped into it.
- Winning Condition: The first player to align four of their pieces in any direction wins immediately:
- Horizontal: Four consecutive pieces in the same row.
- Vertical: Four consecutive pieces in the same column.
- Diagonal: Four consecutive pieces along a diagonal running from upper left to lower right or from upper right to lower left.
- Draw: If the board is completely filled without either player achieving a four-in-a-row, the game ends in a draw.
III. Simple Gameplay Flow
- Decide who goes first and second, then take turns placing pieces.
- In each turn, you may place only one piece at the top of a single column.
- The first player to form a line of four wins; if the board fills up, the game is a draw.
