Duel PvP Connect strategy: Connect 4, 5 and 6, threats and the clock

How Connect works on Duel

These rules come from the Connect rules panel, read on October 14, 2026. Players take turns dropping a piece into a column; it falls to the lowest free cell. Line up four, five or six pieces, across, up or diagonally, to win, matching the variant you picked.

• Variants. The lobby sets the variant: Connect 4 (7x6), Connect 5 (9x7) or Connect 6 (11x8).
• Draws. A full board with no line is a draw and both stakes are refunded.
• Clock. Chess-style clocks: one clock each for the whole game, picked in the lobby as 3+0, 3+2, 5+0 or 5+3, which means minutes on the clock plus seconds gained per move. Your clock only runs on your turn, and the gain is credited the moment you drop a piece, so playing quickly can win time back. No single move is capped, you may spend the lot on one drop, but running out of time loses the game immediately.

Pick your variant and your clock

Connect 4 strategy: centre, threats and tempo

• Take the centre. More lines pass through the centre columns than through the edges, so the middle column is the strongest start. Connect 4 has been solved: with perfect play, the player who moves first wins by starting in the centre column. Duel's rules do not say who moves first, so check in the game.
• Build threats. A threat is three in a line with the fourth cell open. Make two threats at once, a double threat, and your opponent cannot block both.
• Block first, attack second. Before every move, check whether your opponent has three in a line. If so, block it.
• Do not give them the cell above. A piece that lets your opponent drop on top and complete a line loses the game.
• Odd and even rows. As a rule of thumb, the player who moves first benefits from threats on odd rows (counting from the bottom) and the second player from threats on even rows, because of how the columns fill up.

Connect 5 and 6: bigger boards, longer plans

The same ideas apply on the 9x7 and 11x8 boards, with differences that tend to follow from the longer line:

• Defence is easier. A longer line gives you more chances to spot and block a plan, so a single threat rarely wins. Aim for several overlapping lines.
• Draws are more likely. A full board refunds both stakes, so if you are a better player, keep making new threats rather than settling.
• The centre still matters, but with more columns, side columns are more useful than on the 7x6 board.
• Watch the diagonals. Long diagonals are easy to forget on a big board and are where many late wins come from.

Managing the clock

The clock is part of the game: running out of time loses immediately, even if you are winning on the board.

• Play the obvious moves fast. Forced blocks and natural centre moves need no long thought. The seconds you save are for the critical moves.
• Use the increment. With 3+2 or 5+3 the extra seconds are credited the moment you drop a piece, so quick replies can add time to your clock.
• Spend time where it matters. The rules let you spend the whole clock on one drop. Do that when you face a choice between blocking and attacking, not on move two.
• Pick a clock you can handle. If you panic when the clock is low, choose 5+3 and keep a buffer.

Reading your opponent

Common mistakes

• Not checking your opponent's three-in-a-line before every move.
• Dropping a piece that gives your opponent the cell above.
• Spending minutes on the first few moves.
• Choosing a clock that you cannot manage.
• Playing only one line at a time on a big board.
• Using a solver or engine during a match. It is cheating, and Duel can close the account.
