Four Men's Morris · 下士棋
Two of yours beside one of theirs takes it, unless the row is full. Crowd the board and captures stop working.
两子夹一子就吃，可整行占满时反而吃不成。子越多，吃法越难用。
四子攻防，二打一吃子
Four pieces and two-on-one captures
玩法要点
- 棋子：双方各 4 枚
- 棋盘：4 × 4 网格
- 吃法：二打一
Quick start
- Move one step horizontally or vertically; win by reducing the rival to one piece or blocking all their moves.
- A newly formed own–own–rival line captures the rival, but a full row or column prevents capture.
快速上手
- 沿横竖线走一格，把对方吃到只剩一子或困住即可获胜。
- 刚走出的“己己敌”可以二打一，整行或整列站满则不能吃。
Rules
Board and Setup
Play on a 4 × 4 grid. One player’s four pieces start on the bottom row; the other player’s four pieces start on the top row.
Capture until the opponent has only one piece left or cannot move.
Movement
Take turns moving one piece up, down, left, or right into an adjacent empty cell.
Diagonal moves, jumping, and moving onto an occupied cell are not allowed.
Two-on-One Capture
After a move, two adjacent friendly pieces followed by one opposing piece in the same row or column capture that opposing piece.
The pattern must be formed or joined by the piece that just moved.
Full-Line Exception
No capture occurs when all four cells in that row or column are occupied.
A move that does not create “two adjacent friendly pieces + one enemy + one empty cell” is also safe.
Winning and Timer
Win by reducing the opponent to one or zero pieces. In this version, a player with no legal move also loses.
Each turn lasts 60 seconds. When time expires, the turn passes automatically.
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
棋盘为 4 × 4 网格。一名玩家的四枚棋子摆在底行，另外一名玩家的四枚棋子摆在顶行。
轮流吃掉对方的棋子，让对方只剩一枚或者走不动，就赢了。
行棋规则
双方轮流移动一枚己方棋子，只能向上、下、左、右走到相邻空格。
不能斜走、跳跃或停在已有棋子的格子上。
二打一吃子
移动后，如果同一行或同一列上，自己的两枚棋子挨在一起，紧挨着又是一枚对方棋子，就能吃掉它。
只有刚刚这一步棋走出来的组合才算数。
满行不吃
如果这一整行或整列的四个位置都站满了棋子，就不能二打一。
没有摆成“两个自己的棋子 + 一个对方棋子 + 一个空位”这个样子，也不会吃子。
胜负与计时
把对方棋子减少到一枚或零枚即可获胜；本版本中，对手没有任何合法走法时也判负。
每步限时 60 秒。时间用尽后，本回合结束并自动轮到对方。
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。
