Rules

  • Take turns placing one stone on any empty cell. Stones never move.
  • Red connects top and bottom edges. Blue connects left and right.
  • First connected path wins the round. A full board always has exactly one winner.
  • Swap: right after the opening stone, the other player may take the opening role (Red, with that stone) instead of placing.
  • Running out of turn time or bank loses the round, not the series.
