Weiming Shuang Cheng Chess III · 未名双承棋之三
Here the shared piece sits off to one side rather than in the middle, so the lever that decides the game is nowhere near the centre.
这一版的共用子靠在最左边：决定胜负的那根杠杆，根本不在棋盘中央。
三子围堵，公用棋子靠边
Three pieces each, the shared piece sits off to the side
玩法要点
- 棋子：双方各 3 枚，另有 1 枚公用
- 棋盘：9 点，公用棋子在最左侧
- 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 on the far left, 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，或者选最左侧那枚公用棋子，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 9 points: a row of three on top, a row of three on the bottom, and the shared piece's own point off to the far left. Picture the board as two quadrilaterals side by side: the right one (top-middle/top-right/bottom-right/bottom-middle) has no diagonal; the left one (top-left/top-middle/bottom-middle/bottom-left) is missing its left edge but has both diagonals, crossing at a real point in the middle. The shared piece's own line continues past that crossing point to a second point — the midpoint of the vertical line straight below the top-middle spot, splitting that line into two segments.
One player's 3 pieces start on the top row, the other player's 3 pieces start on the bottom row. One more piece — shared by both players — starts at the far-left point; the two crossing points in the middle start empty.
Movement and the Shared Piece
Take turns moving one of your own pieces, or the shared piece on the far left, 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 9 个棋点：上面一排三点、下面一排三点，公用棋子摆在最左侧、单独一个位置。整块棋盘像左右两个四边形拼在一起：右边的四边形（上中/上右/下右/下中四个角）没有对角线；左边的四边形（上左/上中/下中/下左四个角）没有左边这条竖线，但有两条对角线，在中间交叉，交叉点是一个真实棋点。公用棋子的横线从这个交叉点继续往右延伸，终止在上中点正下方那条竖线的中点上，把那条竖线分成两段。
一名玩家的 3 枚棋子摆在上面一排三点，另一名玩家的 3 枚棋子摆在下面一排三点。最左侧另外放一枚谁都能用的棋子，中间那两个交叉点开局都是空的。
行棋与公用棋子
双方轮流选一枚自己的棋子，或者选最左侧那枚公用棋子，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。
