♟️ Four in a Row Duel

Four in a Row Duel is a fast, tactical disc-dropping duel on a sun-washed amber board with a cosy glow, played on a 7-wide, 6-tall grid where you race the owl to connect 4 in a row. Tap a column, gravity does the rest, and a quiet game of stacking suddenly becomes a knife-fight of threats and blocks. Across, down or diagonally — any unbroken line of 4 ends it. The trick, as every veteran knows, is the double threat: build two ways to win at once and the owl can only block one. The AI opponent plays the centre first, looks several moves ahead with alpha-beta search, and pounces on any open three, so loose play is punished instantly. The owl offers a steady, fair challenge — approachable but happy to punish careless moves. Four in a Row Duel loads in seconds, scales to any phone or desktop, and resets with one tap for the inevitable best-of-seven. No download, no sign-up — just drop, connect and celebrate.

How to play

• Tap a column to drop your red disc into the lowest open slot.
• Stack discs to build horizontal, vertical or diagonal lines.
• Block the owl the moment it threatens a connecting row.
• Set up a 'double threat' so the owl cannot block both.
• Connect the target number in a row to win.
