Four in a Row
Drop, connect, four in a row.
Drop your pieces down the columns and connect four in a row — across, up-down, or diagonal — before anyone else. Play head-to-head, or add a third player for a bigger board.
Play Connect 4 online free
A simple web version of Connect 4 from the PartyAt app. Two players share one device: tap a column to drop your disc, and the first to line up four — across, down or diagonally — wins. Free, no install, and it keeps working offline.
The PartyAt app adds CONNECT4 TRIO, a three-player mode on a bigger board where the drop order rotates each round — plus the rest of the party game collection.
How to play — rules
- The number of players in the lobby sets the mode automatically — 2 players means Connect-4, 3 players means the bigger Connect-4 Trio board.
- With 3 players, you also choose whether to drop pieces in turn order or all at the same time.
- Decide the turn order and start the match.
- Pick a column and drop your piece in — gravity stacks it into that column's lowest open space.
- Keep taking turns until someone connects four in a row, or the board fills up completely.
How to win
Whoever lines up four of their own pieces first — across, up-down, or diagonally — wins. If the board fills up with nobody connecting four, it's a draw.
Tips & strategy
- Spot your opponent lining up three in a row (a live threat), and block that column before they can complete it.
- In "drop at the same time" mode, also weigh the risk that another player picks the same column as you.
FAQ
- How big is the board?
- The 2-player Connect-4 board is 7x7. Adding a third player switches to the bigger 9x9 Connect-4 Trio board.
- How does "drop at the same time" decide the winner in Connect-4 Trio?
- All 3 players secretly pick a column, and once everyone has chosen, the pieces drop together. Pieces are then resolved one at a time in a drop order that rotates each round, and the round ends the instant someone connects four. If more than one player picked the same column and it fills up first, whoever is left out simply loses that move.
- How many players can play?
- 2 or 3. Two players follow the standard Connect-4 rules; adding a third switches to Connect-4 Trio on a bigger board.
- Is this the same game as Connect 4?
- "Connect 4" is a trademarked name for the classic 7×6 version of this game family. PartyAt's Four in a Row is the same drop-and-connect idea with its own twists — up to three players and a simultaneous-drop mode.
