Shuang Cheng Chess: Twin Kites · 双城棋
Two kite-shaped halves bridged only by the pieces you both own, so crossing to the other side means asking your opponent's permission.
两只风筝形的半盘，只靠双方共有的子搭桥：想过到对面，得先过对手这一关。
四子对垒，两座风筝靠双城搭桥
Four pieces each, two kite-shaped halves bridged by the shared pieces
玩法要点
- 棋子：双方各 4 枚，另有 2 枚公用
- 棋盘：12 点，两座风筝形棋盘搭桥相连
- 获胜：让对手无棋可走
Quick start
- A player who has no legal move at all — not even either shared piece — loses right away.
- Take turns moving one of your own pieces, or either shared piece, one step along a line to an adjacent empty point. No jumping, no capturing.
- The same player can move a shared piece on consecutive turns of their own. But once either shared piece was just moved, the other player cannot move any shared piece 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——两枚双城也都动不了——就算输了。
- 双方轮流选一枚自己的棋子，或者选任意一枚“双城”，沿连线走一步到相邻的空棋点。不能跳跃，也不能吃子。
- 同一方可以连续动双城；但只要刚才走的是任意一枚双城，对方下一回合不能紧接着也动双城，要等对方走完一步别的棋子之后，双城才能再被对方动。
Rules
Board and Setup
The board is two separate kite shapes side by side: each kite's top edge is two directly-connected points, its bottom edge is two more, and a shared piece sits at its center with four edges reaching the kite's four corners. The two kites aren't connected directly — they're bridged by one unoccupied peak above the board and one below, each reached from the inner top corner of both kites (for the top peak) or the inner bottom corner of both kites (for the bottom peak).
One player's 4 pieces start on the top edges of both kites, the other player's 4 pieces start on the bottom edges of both kites. The two shared pieces sit at the center of each kite; the top and bottom peaks start empty.
Movement and the Two Shared Pieces
Take turns moving one of your own pieces, or either shared piece, one step along a line to an adjacent empty point. No jumping, no capturing.
The same player can move a shared piece on consecutive turns of their own. But once either shared piece was just moved, the other player cannot move any shared piece 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 either shared piece — loses right away.
The core idea is to control the top and bottom bridge peaks and use the shared pieces to trap the other side's pieces with nowhere left to step.
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
棋盘由左右两座独立的“风筝”组成：每座风筝顶边两点直连，底边两点直连，正中心放一枚公用的“双城”棋子，用四条边分别连风筝的四个角。左右两座风筝不直接相连，靠棋盘最上方、最下方各一个没有落子的尖角搭桥——两座风筝挨着中线的那个角，分别连到共用的顶部尖角和底部尖角。
一名玩家的 4 枚棋子摆在左右风筝的顶边（4 点），另一名玩家的 4 枚棋子摆在左右风筝的底边（4 点）。两枚公用的“双城”棋子分别摆在左右风筝的正中心，最上方和最下方的尖角开局留空。
行棋与两枚双城
双方轮流选一枚自己的棋子，或者选任意一枚“双城”，沿连线走一步到相邻的空棋点。不能跳跃，也不能吃子。
同一方可以连续动双城；但只要刚才走的是任意一枚双城，对方下一回合不能紧接着也动双城，要等对方走完一步别的棋子之后，双城才能再被对方动。
谁赢
轮到某一方却无棋可走——两枚双城也都动不了——就算输了。
围堵的思路：抢占顶部和底部的尖角搭桥点，配合双城把对方的棋子逼到没有空位可走。
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。
