Shuang Cheng Chess: Ambush from Ten Sides · 双承棋之十面埋伏
The widest board in the family — five pieces a side across thirteen points, with room to set an ambush instead of a blockade.
家族里最宽的一张盘，双方各五枚子，终于宽到可以设伏，而不只是堵路。
五子围堵，棋盘最宽
Five pieces each on the widest board in the family
玩法要点
- 棋子：双方各 5 枚，另有 1 枚公用
- 棋盘：13 点，宽扁形
- 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 middle, 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，或者选正中间那枚公用棋子，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 13 points: a row of five on top and a row of five on the bottom, plus three more points in the middle (left, the shared piece, right) — the two middle side points start empty.
One player's 5 pieces start on the top row, the other player's 5 pieces start on the bottom row. One more piece — shared by both players — starts at the exact middle.
Movement and the Shared Piece
Take turns moving one of your own pieces, or the shared piece at the middle, 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 13 个棋点：上面一排五点、下面一排五点，中间还有三点（左、公用棋子、右），中间的左右两点开局是空的。
一名玩家的 5 枚棋子摆在上面一排五点，另一名玩家的 5 枚棋子摆在下面一排五点。正中间放一枚谁都能用的棋子。
行棋与公用棋子
双方轮流选一枚自己的棋子，或者选正中间那枚公用棋子，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。
