About Ultimate Connect 4
Connect 4 is one of those games almost everyone has played at some point, and the rules take seconds to learn. Players take turns dropping pieces into the columns of an upright grid, and each piece falls to the lowest open space. The first player to line up four pieces of their color horizontally, vertically, or diagonally wins. Simple as that sounds, there is real strategy underneath, because every move can either build your own threat or shut down your opponent's.
The feature that sets Ultimate Connect 4 apart is the adjustable board. Instead of always playing on the same grid, you can choose the number of rows and columns. A wider board gives you more space to set up multiple threats, while a smaller one leads to tight, tense matches where a single mistake can decide the winner. Everything is controlled with the mouse, so you just pick the column where you want your piece to land and watch it drop.
How to Play Ultimate Connect 4
- Choose how many rows and columns you want on the board before starting a match.
- Click a column to drop your piece, which falls to the lowest empty space in that column.
- Take turns with your opponent, watching each new piece for lines that are starting to form.
- Block any spot where your opponent could complete four in a row on their next turn.
- Connect four of your pieces horizontally, vertically, or diagonally to win the game.

Tips and Tricks
- Claim the center column early. Pieces in the middle can be part of more possible lines than pieces along the edges.
- Always check for your opponent's three in a row before moving. Blocking an immediate threat beats starting a new line of your own.
- Try to create two threats at once. Your opponent can only block one, which often hands you the win.
- Be careful about filling the space directly below a spot your opponent needs, since it lets them drop a piece right into it.
- Experiment with different board sizes. Larger grids reward long-term planning, while smaller ones test how quickly you can spot danger.

Ultimate Connect 4 FAQ
Can you change the board size in Ultimate Connect 4?
Yes. You can choose the number of rows and columns, which lets you switch between a classic feel and bigger or smaller boards that change how much room you have to build and block lines.
Do diagonal lines count?
They do. Four pieces of your color in a row win whether the line runs horizontally, vertically, or diagonally. Diagonal lines are often the easiest to miss, so keep a close eye on them for both players.
What is the best first move in Connect 4?
On a standard board, the center column is usually the strongest opening because it connects to the most possible lines. On custom board sizes, aim for the middle columns for the same reason.
Can I play Ultimate Connect 4 on a school Chromebook?
Yes. Ultimate Connect 4 runs in the Chrome browser on Chromebooks, Windows PCs and Macs with nothing to install. It is designed for a keyboard and mouse, so it plays best on a computer rather than a phone.
