Grand Reversi大リバーシ

The flipping game on a 10×10 board: a longer game, with more middle to fight over before anyone reaches an edge.

The big board the play-by-mail sites kept beside the usual one — ItsYourTurn called it Flipversi 10×10. The same rules, thirty-six more squares, and the corners farther from everything.

Inspired by Othello. The name belongs to its owner; this is our own version of the rules.

Also known as Flipversi 10x10.

Object目的

Finish with more discs than the other colour.
The game ends when neither colour has a legal move — usually a full board. Equal counts are a draw.

Board盤

A 10×10 board.

Play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.

House rules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.
10×10, and only that. Ninety-six discs go down instead of sixty, and the edges are two squares farther from the centre, so the opening runs long before either side touches one.
