Othello (Reversi) instructions

Black and White move alternating. (It is shown, whose turn it is and which moves are possible.)

• Initially the 4 middle fields need to be filled.
• Afterwards,
  • the new stone must be placed in a way, that between the new stone and another stone of the same color (horizontally, diagonally or vertically) stones of the opposite color are enclosed without gaps.
  • The enclosed stones (possibly in multiple lines at once) switch color from the opposite to the current players color.
• In case no more more moves are possible,
  • for the player on turn, the player is skipped and the other player can move again.
  • for any player, game ends. The player wins who has the majority of stones colored in his color.
