SepoGames › Drop Four

Drop Four — free online connect four

Drop your pieces into the grid and line up four in a row — across, down or diagonally — before your opponent does. Play against a bot that actually thinks ahead, with four skill settings from Easy up to Brutal, or hand the phone back and forth in two-player mode. Free, no download, no sign-up.

How to play

1. Tap a column to drop your piece into it.
2. The first player to line up four in a row wins.
3. Rows, columns and both diagonals all count.
4. Undo takes back your last move and the bot's reply.
5. Pick Two players from Settings to play against a friend on the same phone.

Tips

• Take the centre column early. More winning lines run through it than any other.
• Watch for the double threat — a move that creates two ways to win at once cannot be blocked.
• Count before you drop. Filling a column can hand your opponent the square above it.
• Brutal looks seven moves ahead. Beating it needs a plan, not a lucky line.
