Surround the Tiger · 围虎棋
One tiger, sixteen dogs. The tiger eats two by stepping between them, so a dog's only real protection is another dog standing behind.
虎从两犬中间一钻就吃两只，所以一只犬真正的护身符，是身后还站着另一只犬。
一虎居中，十六犬合围
One tiger at the center, sixteen dogs closing in
玩法要点
- 棋子：虎方 1 枚，犬方 16 枚
- 棋盘：25 点米字格
- 获胜：虎吃满 6 犬，或犬方把虎困死
Quick start
- The tiger moves first; step along a line to an adjacent empty point; the beast wins by capturing six dogs, and dogs win by trapping it.
- The beast can capture two dogs by moving directly between them.
- If another dog stands directly beyond either flanking dog, the capture is blocked.
快速上手
- 虎先走，双方沿线走到相邻空点；猛兽吃满六犬获胜，犬围住猛兽获胜。
- 猛兽主动走进紧邻的两犬之间，可同时挑吃两犬。
- 两犬外侧若还紧挨第三只犬，这次不能挑吃。
Rules
Board and Setup
The board is four combined grid cells with 25 points total, connected by straight and diagonal lines.
The tiger starts at the very center. The 16 dogs fill the entire outer ring.
Movement
One player plays the tiger, the other plays the dogs. The tiger moves first, then players alternate.
Each move slides one piece a single step along a line to an adjacent empty point — no jumping over other pieces.
Insertion Capture
After the tiger moves, if it lands directly between two dogs on the same line, both dogs are captured.
But if either of those two dogs has a third dog right behind it on that same line, the capture doesn't happen — both flanking dogs must be standing alone.
Winning
The tiger wins by capturing 6 dogs.
The dogs win by trapping the tiger with no legal move.
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
棋盘由四个米字格拼合而成，一共 25 个棋点，横、竖、斜都画着线。
开局时，虎摆在棋盘正中心，犬方 16 枚棋子摆满最外一圈。
行棋规则
一名玩家扮演虎，另一名玩家扮演犬方，轮流走子，虎先走。
每次只能沿直线或斜线走一步，走到相邻的空点，不能跳过其他棋子。
挑吃
虎走完一步后，如果正好夹在同一条直线上相邻的两枚犬中间，两枚犬会同时被吃掉。
但如果这两枚犬里有一枚，往外一格还紧挨着第三枚犬，这次就不能吃——被夹住的两枚犬必须各自都是孤立的。
胜负条件
虎吃满 6 枚犬即可获胜。
犬方如果把虎逼到无路可走，犬方获胜。
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。
