Twelve Men's Morris · 十二子直棋
Twelve pieces on twenty-four points, and a mill made while placing swaps their piece for yours. The fight starts on move one.
二十四个点摆十二枚子，布子阶段成直就把对方的子换成自己的——第一手就是战斗。
三子连成一条线即可吃子，吃光对方获胜
Line up three to capture; win by taking all the opponent's pieces
玩法要点
- 棋子：双方各 12 枚
- 棋盘：三个同心正方形，24 个棋点，20 条可成「直」的线
- 获胜：吃光对方棋子
Quick start
- Take turns placing, then step along lines; after placement, the last placer moves first.
- A line of three captures; during placement replace the captured piece with your own, and during movement remove it, preferring pieces outside lines.
- Capture every rival to win; when blocked, remove one rival piece and then move instead of losing.
快速上手
- 先轮流布子，再沿线走一格；放完后由后放子的一方先走。
- 三子成“直”可吃子，布子时用己子押住被吃点，走子时直接移除敌子；优先吃散子。
- 吃光对方获胜；无路可走可先拔对方一子，再继续走，不按困死判负。
Rules
Board and Setup
The board is three nested squares, joined by eight lines running through the corners and edge midpoints — 24 points where lines cross.
Each side has 12 pieces, all in hand. Take turns placing one piece on an empty point.
Mills and Pinning
After placing, if you have three pieces in a full line (a mill), capture one opponent piece. Forming two mills in one move captures two.
You may only capture pieces not in a mill; if all the opponent's pieces are in mills, you may take any.
During placement, capturing is done by "pinning": remove the opponent's piece and place one of your own on that point.
Movement
Once both sides have placed all 12, movement begins — the player who placed second moves first.
Move one of your pieces one step along a line to an adjacent empty point. No landing on an occupied point, no jumping.
Forming a mill by moving also captures — now the piece is removed directly, no pinning. Take a non-mill piece first.
Pull
If it's your turn and not one of your pieces can move, first remove any one opponent piece, then move. This is called a "pull."
Zhi Qi is not won by blockade — trapping the opponent isn't a win; they pull one of your pieces and play on.
Winning
Win by capturing all the opponent's pieces.
The first placer has an opening edge (decides the last empty point, forms the first mill more easily); the second placer should build more favorable shapes to close the gap.
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
棋盘是三个套在一起的正方形，四个角和四条边的中点之间用八条线连起来，线的交点一共 24 个棋点。
双方各 12 枚棋子，全在手里。轮流把棋子放到空棋点上，一次放一枚。
成「直」与押子
放子后，如果自己有三枚棋子连成一条完整的线（一条「直」），就可以吃掉对方一枚棋子。一步同时连成两条「直」可以吃两枚。
只能吃对方不在「直」里的散子；如果对方所有棋子都在「直」里，才可以任意吃。
布子阶段的吃子叫「押子」：把对方那枚棋子拿掉，再用自己的一枚棋子占住那个点。
走子
双方各 12 枚都放完后进入走子阶段，由后放子的一方先走。
取自己一枚棋子，沿线走一步到紧挨着的空点，不能走进有棋子的点，也不能跨过棋子。
走子后连成「直」同样可以吃子，这时直接把对方棋子移走，不用押子；优先吃「直」以外的散子。
拔子
轮到自己却一枚棋子都动不了时，可以先除去对方任意一枚棋子，然后再走棋，这叫「拔子」。
直棋不以困死对方取胜——把对方逼到无路可走并不算赢，对方拔掉你一子就能继续。
胜负
把对方棋子全部吃完即获胜。
先放子的一方开局有优势（能决定最后一个空点、也更容易先连成「直」），后放子的一方要靠多造有利棋型来缩小差距。
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。
