Zhonglou Shuang Cheng Chess · 钟楼双承棋
Another seven-point board, strung differently: the same two pieces a side, but the shared piece now reaches other lines.
同样七个点，线却串得不一样：共用子够得着的地方，和景县那张盘完全是两回事。
两子围堵，公用棋子靠边
Two pieces each on a compact 7-point board
玩法要点
- 棋子：双方各 2 枚，另有 1 枚公用
- 棋盘：7 点
- 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. On such a small board, every move counts.
- Take turns moving one of your own pieces, or the shared piece, 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。棋盘小，每一步都要想清楚。
- 双方轮流选一枚自己的棋子，或者选公用棋子，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 7 points: two top corners, two bottom corners, the shared piece sitting just below the top-right corner, and one empty point flanking it on each side (the right-hand one also connects to the top-right corner and the bottom-right area).
One player's 2 pieces start on the top corners, the other player's 2 pieces start on the bottom corners. One more piece — shared by both players — starts just below the top-right corner; the two points flanking it start empty.
Movement and the Shared Piece
Take turns moving one of your own pieces, or the shared piece, 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. On such a small board, every move counts.
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 7 个棋点：上边两角，下边两角，公用棋子在中间偏上，公用棋子左右各接一个空棋点（右边那个空棋点还同时连着上边右角和下边右侧的角）。
一名玩家的 2 枚棋子摆在上边两角，另一名玩家的 2 枚棋子摆在下边两角。中间偏上的位置放一枚谁都能用的棋子，公用棋子左右两侧的棋点开局是空的。
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。棋盘小，每一步都要想清楚。
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。
