Jinmen Defense Chess · 金门防御棋
Two of yours take one of theirs; three take two. Bring enough pieces to a line and the arithmetic does the work.
两子吃一子，三子吃两子。把人手带够，剩下的交给算术。
两子吃一子，三子吃两子
Two capture one, three capture two
玩法要点
- 棋子：双方各 8 枚
- 棋盘：29 个棋位
- 吃法：紧邻的棋子多吃少
Quick start
- Move along a line to an adjacent empty point; win by reducing the rival to one piece or blocking them.
- A new two-own/one-rival run captures one, or three-own/two-rival captures two, with no extra pieces anywhere on the line.
- The larger group must actively move into formation; moving away or a rival entering it does not trigger capture.
快速上手
- 沿线走到相邻空点，把对方吃到只剩一子或困住获胜。
- 新走出“己己敌”吃一，或“己己己敌敌”吃二；整条线上不能有额外棋子。
- 必须由多子一方主动走入成型，少子方送入或撤子露出棋形都不算。
Rules
Board and Setup
The board can be drawn anywhere. Each side has 8 pieces, set up at the top and bottom, with a wide-open middle.
This is a well-known folk game — all you really need is a patch of dirt and a handful of stones.
Movement
On your turn, slide one of your pieces one step along a drawn line to an adjacent empty spot.
Two Capture One
Line up two of your pieces side by side, with one enemy piece immediately next to them on the same line, and that enemy piece is captured.
The whole line must have exactly those three pieces — no more on either end, or it doesn't count.
Three Capture Two
Line up 3 of your pieces. Put 2 enemy pieces right next to them.
If the whole line has exactly those 5 pieces, capture both enemy pieces.
Whose Move Counts
Only the larger side capturing by completing this pattern with their own move counts as a capture.
If the outnumbered side walks into it themselves, that's not a capture.
If the larger side reveals it by pulling a piece away, that's not a capture either.
Winning
Reduce the opponent to just 1 piece, or leave them with no legal move at all, and you win.
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
棋盘随地可画，双方各有 8 枚棋子，摆在棋盘上下两端，中间留出一大片空位。
这是一种流传很广的民间棋，随便找块空地、捡几颗石子就能玩。
行棋规则
轮到你时，把一枚己方棋子沿棋盘上画出的线走一步，走到相邻的空位。
两子吃一子
把己方两枚棋子走成紧挨着排在一条线上，紧接着的下一个位置正好是一枚敌方棋子，就能把它吃掉。
这一整条线上必须刚好是这三枚棋子，前后都不能再多一枚棋子，多了就不算。
三子吃两子
己方 3 枚棋连在一起，旁边紧接着是敌方 2 枚棋。
整条线上刚好只有这 5 枚棋，就能把敌方 2 枚一起吃掉。
谁走的这一步才算数
只有棋子多的一方自己走出这一步、刚好凑成上面的局面，才算吃子。
如果是棋子少的一方自己走过去、送上门的，不算被吃。
如果棋子多的一方是撤走一枚棋子、无意中露出这个局面的，也不算吃子。
胜负条件
把对方吃到只剩 1 枚棋子，或者轮到对方却一步都走不出来，就获胜了。
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。
