Nine-piece morris where a player down to three pieces may fly anywhere
玩法要点
- 棋子：双方各 9 枚
- 棋盘：三个同心正方形，24 个棋点，16 条可成「直」的线
- 获胜：把对方吃到只剩两枚
Quick start
- Each player has 9 pieces: take turns placing them on empty points, then slide them along the lines.
- Three of your pieces in a row along a marked line let you take one of the other player’s pieces.
- Win by leaving the other player with two pieces, or with no move at all.
快速上手
- 双方各 9 枚棋子，先轮流把棋子放到空点上，放完再沿线走一格。
- 三枚自己的棋子连成一条线（一条「直」），就可以拿掉对方一枚棋子。
- 把对方吃到只剩两枚，或者让对方一步也走不了，就赢了。
Rules
Board and Setup
Three nested squares, joined by a line between the middle of each side, with twenty-four points in all.
Each player holds 9 pieces at the start. Players take turns placing one piece on any empty point.
Rows and Captures
Three of your own pieces in a row along a marked line is called a mill, and it lets you take one of the other player’s pieces at once.
A move that completes two mills at the same time still takes only one piece.
A piece inside a mill cannot be taken; if every one of the other player’s pieces sits in a mill, any of them may be taken.
Moving
Once every piece has been placed, players move instead: slide one of your pieces along a line to an empty point next to it.
A player down to three pieces may fly: lift one piece and drop it on any empty point, without following the lines.
Winning
A player left with two pieces in hand and on the board together can never make another mill, and loses.
A player who cannot move a single piece on their turn also loses.
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，四条边的中点之间用线连起来，一共 24 个棋点。
双方各 9 枚棋子，一开始全在手里。轮流把棋子放到空棋点上，一次放一枚。
成「直」与吃子
三枚自己的棋子连成一条完整的线，就叫成了一条「直」，可以马上拿掉对方一枚棋子。
一步同时连成两条「直」，也只能拿掉一枚。
在「直」里的棋子拿不走；要是对方的棋子全都在「直」里，那就哪一枚都可以拿。
走子
手里的棋子放完以后，改成走棋：每次把一枚自己的棋子沿着线走到旁边的空点上。
棋子少到只剩三枚的一方可以「飞」：把一枚棋子直接放到棋盘上任意一个空点，不用沿线走。
胜负
一方的棋子（手里的加上棋盘上的）只剩两枚时，就再也连不成一条「直」，这一方就输了。
轮到一方走棋，却一枚棋子都动不了，这一方也输了。
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。
