Setting up

Four discs start in the centre: two of each colour, placed diagonally. Black (or dark) moves first.

Making a move

  1. Place a disc so that, in a straight line from it, one or more of your opponent's discs are trapped between it and another of your discs.
  2. Lines can go across, up and down, or diagonally, in all eight directions.
  3. Every trapped disc in every direction flips to your colour.
  4. A move must flip at least one disc. If you have no legal move, you pass. If you can move, you must.

End of the game

The game ends when neither player can move, usually because the board is full. The player with the most discs wins. Equal counts are a draw.

Strategy tips

  • Corners are gold. A disc in a corner can never be flipped.
  • Avoid the squares right next to an empty corner. They often hand your opponent that corner.
  • Flipping lots of discs early is rarely good. Having more choices of move (mobility) matters more.
  • Edges are strong when they connect to a corner you own.
