A simple guide: the goal, how discs fall, four in a row horizontally, vertically and diagonally, controls on muta.pro and tips for beginners. Five minutes — and you are ready to play.
Connect Four is a fast duel on a vertical board 7 columns × 6 rows. Players take turns dropping their discs into the columns, and each disc falls to the lowest free cell. The winner is the first to line up four of their discs in a row — horizontally, vertically or diagonally. If the board fills up and there is still no line of four — it is declared a draw.
The board is empty: 7 columns and 6 rows. One player has red discs, the other has gold ones. Red moves first; in the next game the right to the first move passes to the opponent. You can play against the bot or two players on one device — the mode is switched with the buttons above the board.
Seven vertical columns of six cells each. All cells start empty — discs only enter from the top, through the chosen column.
On your turn you pick any column that still has room and drop a disc into it. You do not move twice — after dropping, the turn passes to your opponent.
A disc does not stay at the top: it falls down and lands on the lowest free cell of the column — on top of the discs already there. You cannot choose exactly where it lands, only which column to drop it into.
The goal is to line up four of your discs in a row: along a row, a column or a diagonal. As soon as the line is complete, the game ends instantly with a win.
If your opponent already has three discs in a row with an open extension — block that spot with your own disc before they can add a fourth.
The strongest move is to create two threatening lines at once with a single move. The opponent can only block one, and you complete the other to win.
If all 42 cells are filled and no one has four in a row — the game ends in a draw, and you can start a new one.
Typical situations on a 7×6 board. Your discs are red, the opponent's discs are gold. The winning line is outlined in white, and the dashed cell marks where you should drop a disc.
The game ends as soon as someone lines up four discs in a row — the line is highlighted on the board, and a card with the result and the series score appears. All directions count: horizontal, vertical and both diagonals. But if the board is completely full and no one has a line of four — it is a draw. The win count is kept across the whole series of games and is reset with a separate button.
The central column is part of the largest number of possible lines. Whoever holds the center has a better chance of getting four.
Diagonal threats are the hardest to spot. Check the slanted lines more often — both yours and your opponent's.
Try to build your position so that your next move creates two lines at once. The opponent will block one, but not the other.
Before dropping, consider: are you opening a winning cell above for your opponent? Sometimes it is better to play another column.
Connect Four theory has proven it: the strongest first move is in the central column D. But the center alone is not enough — what matters is what you build next. Three reliable schemes set the rhythm of the game and keep your opponent from seizing the initiative.
Place your second and third pieces in D again, building the vertical. This is less a "four in a column" threat than control of the axis: every piece in the center works both diagonals at once.
If the opponent has taken the center, answer in the same column D on top, or right next to it — in C or E. Giving up the center for free means starting the game at a deficit that a strong opponent will not let go.
Columns A and G belong to the fewest lines. In the opening they are almost always weaker — save them for later, when the edge becomes part of a concrete combination rather than a "nothing-better-to-do" move.
The bottom two rows of the 7×7 board are shown partially: the center (D) is held by red, and the axis of the game is built around it.
An experienced player doesn't count every cell — they scan the board by patterns. Three habits speed up your evaluation of a position and all but eliminate blunders out of nowhere.
Before your move, quickly check whether the opponent has three pieces in a row with an open continuation. If they do and it can really be completed — block first, everything else after.
The brain catches horizontals and verticals on its own, but not the slanted lines. Run your eyes along both diagonals deliberately: that's exactly where overlooked threats hide.
Every move opens the cell above it. Ask yourself: won't it become a winning cell for the opponent? Half of all losses are a voluntary gift of the cell above.
Three ○ in a row with an open cell to the left (gold) — a threat that must be closed immediately.
Gravity isn't an obstacle but a tool. Cells in a column fill strictly from the bottom up, so you can "charge" a winning cell in advance in such a way that the opponent is forced to open it for you himself by dropping a piece beneath it.
The technique works through forced moves: you create a vertical threat, the opponent must close it from above — and with that move places his piece right under your prepared horizontal or diagonal. Your next move completes the four.
The opponent closed the vertical from above (○) and opened the cell over it — red completes the diagonal on the highlighted cell.
When simple threats are exhausted, the game is decided by zugzwang — a position where any move the opponent makes worsens his stance. In Connect Four this works through filling the columns: sooner or later there's nowhere to move except beneath your threat.
Toward the end, assess how many "safe" columns each side has left. If the opponent runs out first, he'll be forced to play beneath your setup.
Don't rush to complete your only threat — sometimes it's better to keep it as the "lock" of the zugzwang: while it hangs there, the opponent can't freely use the column you need.
Every extra move into a neutral column changes the parity of the remaining cells. Before an "empty" move, work out who ends up with the contested cell when the board is played out.
One cell is free (gold); the opponent will have to move only there — right beneath the completion of red's line.
