Gomoku (Five in a Row)

Gomoku, also called Five in a Row, is a stone-placement game on a 15 by 15 board. Share an invite link to play online with a friend, take turns on one device, or choose the computer at Beginner or Advanced level. Free, with no sign-up.

How do you win?

Black moves first. Take turns placing a stone on an empty intersection. Connect five or more stones horizontally, vertically or diagonally to win. A full board without a winner is a draw.

Do six in a row count? Are there forbidden moves?

Six or more in a row also wins. This is freestyle Gomoku: there are no forbidden moves for either color.

Can we play another round?

Choose “Play again” after a result. Online, both players must accept. The score carries over and sides switch by default; tap the next-side line to change them.

How to play

  1. Share an invite link, play together on this device, or choose the computer at Beginner or Advanced level.
  2. Your friend opens the link to join. If you are together, they can enter the 6-character room code on the home page.
  3. Black moves first on the 15 by 15 board. Take turns placing stones on empty intersections; five or more horizontally, vertically or diagonally wins. A full board without a winner is a draw. There are no forbidden moves.
  4. After a game, choose “Play again” to start another round in the same room. Online, both players must accept. Sides switch by default; tap the “Next: you play …” line to swap them. The score carries over.
  5. On a phone, tap once to preview a move, then tap the same spot again to place.
  6. Undo sits below the board. Online Undo needs your friend’s approval. On one device it reverses one move; against the computer it reverses your move and the reply. Finished games cannot be undone.
  7. Resign, also below the board, asks once more and then gives your opponent the round.
  8. Progress is saved in this browser. Return here to try to resume after a refresh or disconnect; online recovery needs both players to reconnect. Changing devices or clearing browser data can prevent recovery.

Returning to a game
