Four in a Row

About Four in a Row

Four in a Row is the kind of game that looks innocent for about ten seconds — then you realize your opponent just set up a double threat and you're already cooked. Also known as Connect 4, this timeless brain game has been ruining friendships and sparking rematches since the 1970s, and it's still one of the most-played titles on any unblocked games 67 library today.

The premise is dead simple: drop discs into a vertical grid and be the first to line up four of your color — horizontally, vertically, or diagonally. But beneath that simplicity lies genuine strategy. Every move opens and closes possibilities, and one careless drop can hand your rival the win. That balance of easy rules and deep tactics is exactly why it keeps pulling players back, whether they're killing five minutes in study hall or grinding ranked matches on unblocked games 66.

How to Play & Controls

Your objective is straightforward: connect four of your discs in a row before your opponent does. The board is a 7-column, 6-row grid, and gravity does the rest — discs fall to the lowest open slot in whichever column you choose.

Controls couldn't be simpler:

• Desktop: Hover over a column to preview your drop, then click to release the disc. Some versions support arrow keys plus Enter for keyboard players.
• Mobile: Tap the column you want. The touch targets are generous, so no precision surgery required.
• Modes: Most versions offer Player vs Player (same device), Player vs CPU with adjustable difficulty, and online matchmaking.

Games end the moment someone connects four, or in a draw if the board fills completely. No timers, no rush — just pure turn-based thinking.

Pro Tips & Strategies

1. Own the center column. The middle column touches every possible four-in-a-row line on the board. Dropping there first gives you the most options and the most threats. Experienced players fight for the center before anything else.

2. Build double threats. A single threat is easy to block. Two threats at once? Your opponent can only stop one. Stack discs so you have two separate winning squares available — that's how you force the win.

3. Watch the row above your opponent's stack. The classic beginner mistake is playing directly on top of a rival's disc, which hands them a free setup. Before every drop, check what you're gifting them.
