Weiming Shuang Cheng Chess II · 未名双承棋之二
A fan-shaped board of eleven points with the shared piece dead in the centre, where four pieces a side leave almost no slack.
扇形盘十一个点，共用子钉在正中央，双方各四枚——谁都没有多余的空间。
四子围堵，公用棋子居中
Four pieces each, the shared piece sits dead center
玩法要点
- 棋子：双方各 4 枚，另有 1 枚公用
- 棋盘：11 点，扇形棋盘
- 获胜：让对手无棋可走
Quick start
- A player who has no legal move at all — not even the shared piece — loses right away.
- Take turns moving one of your own pieces, or the shared piece at the center, one step along a line to an adjacent empty point. No jumping, no capturing.
- If the shared piece was just moved, the other player cannot move it on their very next turn — it becomes movable again once that player has taken one turn with a different piece.
快速上手
- 轮到某一方却无棋可走——连公用棋子也没法动——就算输了。
- 双方轮流选一枚自己的棋子，或者选正中心那枚公用棋子，沿连线走一步到相邻的空棋点。不能跳跃，也不能吃子。
- 如果刚才走的是公用棋子，下一回合对方不能马上再走它，要等对方走完一步别的棋子之后，公用棋子才能再被动。
Rules
Board and Setup
The board has 11 points: a top tip connects to a row of three, and a bottom tip connects to a row of three, with the shared piece at the exact center. Each row's two outer points send a diagonal that crosses and bends at a hidden point before reaching the center (and, on the far side, the opposite row's outer points).
One player's 4 pieces start on the top tip and top row. The other player's 4 pieces start on the bottom row and bottom tip. One more piece — shared by both players — starts at the exact center; the two hidden crossing points start empty.
Movement and the Shared Piece
Take turns moving one of your own pieces, or the shared piece at the center, one step along a line to an adjacent empty point. No jumping, no capturing.
If the shared piece was just moved, the other player cannot move it on their very next turn — it becomes movable again once that player has taken one turn with a different piece.
Winning
A player who has no legal move at all — not even the shared piece — loses right away.
The core idea is to use the shared piece together with your own pieces to trap the other side's pieces in a corner.
Timer
Each turn lasts 60 seconds. When time runs out, the turn passes to the other side automatically.
You can change the difficulty anytime in Game Settings.
规则详解
棋盘与开局
棋盘有 11 个棋点：上方尖角连一排三点，下方尖角连一排三点，正中心是公用棋子。上排最外侧两点各连一条斜线，先在一个隐藏点上交叉、拐弯，再分别接到正中心和下排最外侧两点，下排同理。
一名玩家的 4 枚棋子摆在上方尖角和上排三点，另一名玩家的 4 枚棋子摆在下排三点和下方尖角。正中心另外放一枚谁都能用的棋子，两个隐藏交叉点开局是空的。
行棋与公用棋子
双方轮流选一枚自己的棋子，或者选正中心那枚公用棋子，沿连线走一步到相邻的空棋点。不能跳跃，也不能吃子。
如果刚才走的是公用棋子，下一回合对方不能马上再走它，要等对方走完一步别的棋子之后，公用棋子才能再被动。
谁赢
轮到某一方却无棋可走——连公用棋子也没法动——就算输了。
围堵的思路：用公用棋子和自己的棋子一起把对方的棋子堵在角落里。
计时
每步限时 60 秒，时间到了会自动换对方走。
可以在"对局设置"里换一个难度，随时都能换。
