逆リバーシ

Everything turns as usual, but the fewer discs wins.

The giveaway form. Every rule is the same; the object is upside down, so the corners become the last thing you want.

別名はAnti-Flipversi, Anti-Flipversi 6x6。

目的

  • Finish with fewer discs than the other colour. Everything turns as usual; the object is upside down.
  • The game ends when neither colour has a legal move — usually a full board. Equal counts are a draw.

  • A 8×8 board.

手順

  • The centre four squares start with two discs of each colour, on the diagonals.
  • The set-up lets a game start the other way: centre discs placed, or laid by the players.
  • A disc goes only where it brackets one or more of the other colour in a straight run — any direction — with one of your own at the far end. Every bracketed run turns to your colour.
  • A colour with nowhere to go passes, and the other colour plays again. You may not pass while you have a move.
  • When neither colour can move, the discs are counted.

細則

  • Either colour may open, or the first stone may be drawn by lot.
  • The threat reading, hints and the chance-of-winning bar are switched off: there are no lines to read here, only discs to count.
  • 8×8. Giving the other side discs is the whole game; a corner is a liability.
