CONNECT 4
About Connect 4
Our Connect 4 runs the classic four-in-a-row duel on a clean synchronized board, then goes further than the original ever did. Two players get the traditional 6x7 grid, while the 3-4 player mode grows to a 10x10 grid where four colors fight over the same columns.
Pieces obey gravity and fall to the lowest open cell, and the first player to line up four in any direction claims the win and 25 points. For veterans, Hard Mode blocks some holes on the board: blocked cells that pieces stack on top of and that never count toward a line, which quietly rewrites every column read you have ever memorized.
Connect 4 Rules
- Claim a color seat: red, blue, yellow, or green. Two players use a 6x7 board; three or four players use a 10x10 board.
- A random assigned player goes first, then turns rotate in fixed color order.
- On your turn, drop one piece into a column. It falls to the lowest empty cell.
- First player to connect four in a row, column, or diagonal wins and earns 25 points.
- If the board fills with no line of four, the match is a draw.
- In Hard Mode, some holes are blocked: pieces stack on top of them and blocked holes never count in a winning line.
Tips to Win
- Control the center columns. They participate in more possible lines of four than the edges do.
- Build double threats: two ways to win on your next turn that a single opposing piece cannot block.
- Watch the cell your drop exposes. Filling a column can hand your opponent the landing spot they were waiting for.
- In 3-4 player matches, block the player closest to winning even if they are not your biggest rival. Kingmaking loses games.
- In Hard Mode, scan for blocked holes before planning diagonals; a single blocked cell kills the line through it.
Best for
Ideal for anyone who grew up on the plastic original and wants quick, no-setup rounds with a friend online. The 4-player big board and Hard Mode give strategy fans real depth beyond the classic, while the base game stays simple enough for kids and casual family sessions.
