🧱 步步为营Wall Chess
在线步步为营（挡板棋）：9×9 棋盘上双方各有一枚棋子和若干块挡板，谁先走到对面底线谁赢。每回合可以走一步，也可以放一块两格长的挡板拦住对手，但不能把对手的路完全堵死。状态栏实时显示双方到终点的最短步数，可选挡板数量、电脑难度或双人对战。Wall Chess online: on a 9×9 board each player has one pawn and a stock of walls, and the first to reach the far side wins. Each turn either move one step or place a two-square wall to block your opponent — but you may never cut off a player's path completely. Live shortest-path counts for both sides, adjustable wall stock, three computer levels or two players.
“走棋”模式下点绿色圆点移动；切换到横/竖挡板后，点格线交叉处附近放置（蓝色预览表示可以放，红色表示不行）。In Move mode tap a green dot to step; switch to a horizontal or vertical wall and tap near a grid crossing to place it (blue preview = allowed, red = not allowed).
玩法说明与常见问题How to play & FAQ
「步步为营」怎么玩？How do I play Wall Chess?
蓝方从下方出发要走到最上面一行，红方从上方出发要走到最下面一行。每回合二选一：棋子向上下左右走一格（不能穿过挡板；对手挡在面前时可以跳过去，后面有挡板则斜着绕），或放一块挡板。挡板长两格，不能重叠或交叉，而且必须给双方都留一条通往终点的路。Blue starts at the bottom and must reach the top row; Red starts at the top and heads for the bottom. Each turn either move your pawn one square up, down, left or right (not through walls; you may jump over an adjacent opponent, or step diagonally around them if a wall is behind), or place a wall. Walls are two squares long, cannot overlap or cross, and must always leave both players a path to their goal.
什么时候该放挡板？When should I place a wall?
当对手离终点比你近时最需要挡板。好的挡板能让对手多绕很多步，而自己的路线几乎不变；挡板用完后就只能走棋了，所以别太早用光。Walls matter most when your opponent is closer to the goal than you. A good wall adds many steps to their route while barely changing yours — and once your walls are gone you can only move, so don't spend them too early.
为什么有些地方放不了挡板？Why can't I place a wall somewhere?
挡板不能和已有挡板重叠或十字交叉，也不能把任何一方完全封死。预览变红就说明这个位置不合规则。A wall may not overlap or cross another wall, and may not seal either player off completely. A red preview means the spot breaks one of those rules.
