Wu Dao Qi · 五道棋
Flanked pieces go back to their owner's hand instead of off the board. When the 5×5 grid fills up, whoever holds more of it wins.
被夹掉的子不下场，而是回到原主手里。等盘面下满，谁占得多谁赢。
5×5 棋盘轮流落子，用夹吃和反夹吃互相吃子，被吃的棋子回到原主手里，满盘时比谁棋子多
Take turns placing on a 5×5 grid — flank enemy pieces or get flanked yourself to capture, captured pieces return to their owner’s hand, and whoever has more on the board when it fills up wins
玩法要点
- 棋盘：5×5 交叉点，共 25 个棋位
- 棋子：双方各备 25 枚
- 获胜：棋盘下满时，盘面上棋子多的一方获胜
Quick start
- Take turns placing, without moving old pieces; when the board fills, the larger on-board count wins.
- New own–own–rival or own–own–rival–rival runs capture only with empty or edge ends; placement between two or four adjacent rivals counter-captures them.
- Captured pieces return to their owner’s reserves and can be placed again; an empty reserve only skips that turn.
快速上手
- 轮流放子，不移动旧子；棋盘布满后比盘上子数，多者胜。
- 新落子凑成“己己敌”或“己己敌敌”可吃，整段两端须空或到边；被两敌或四敌夹住时可反吃。
- 被吃的子退回原主手中，可再次放；手中无子只跳过回合。
Rules
Start With an Empty Board
The board is a 5×5 grid of intersecting lines, 25 points in all.
Each side has 25 pieces in hand. Players alternate placing on empty points — there is no separate movement phase.
Flanking Capture: Your Pieces Trap Theirs
Place next to an own piece to form own–own–enemy or own–own–enemy–enemy horizontally or vertically. The new piece may be either of the two own pieces.
Both ends of the whole chain must face empty space or the board edge. Any extra piece touching either end prevents this capture.
Capture the one enemy in a two-against-one chain, or both enemies in a two-against-two chain.
Counter-Capture: Walking Into a Trap Backfires — On Them
If the piece you just placed ends up sandwiched between two enemy pieces in a straight line (horizontally or vertically), you capture both of those enemy pieces instead.
If all four orthogonal neighbors of your new piece are enemy pieces, all four are captured the same way.
Captured Pieces Go Back to Their Owner
Unlike most capture games, a captured piece in Wu Dao Qi isn’t removed for good — it returns to its original owner’s hand and can be placed again later.
If a player temporarily runs out of pieces in hand, their turn is simply skipped while the other player keeps placing — the game isn’t over yet.
Board Fills, Most Pieces Wins
The game ends once all 25 points are occupied.
Count each side’s pieces on the board (not in hand) — more wins; equal counts is a draw.
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
空棋盘开局
棋盘是 5×5 的纵横线交叉，一共 25 个棋位。
双方各备 25 枚棋子，轮流往空位上落子，没有单独的走子阶段。
二打一 / 二打二：己方夹敌方
新落子和另一颗己子连在一起，横着或竖着形成“己己敌”或“己己敌敌”。新子可以是两颗己子中的任意一颗。
整段棋子两端外面都必须是空位或棋盘边界，紧贴任何其他棋子都不算。
“己己敌”吃掉一颗敌子（二打一）；“己己敌敌”吃掉两颗敌子（二打二）。
挑吃：敌方反而被自己反杀
新落的这颗棋子如果被两颗敌方棋子夹在一条直线的中间（横向或纵向），就反过来吃掉这两颗夹住自己的敌棋。
如果新落子的上下左右四个方向全部都是敌方棋子，同样反杀，四颗敌棋全部被吃掉。
被吃的棋子回到原主手里
和大多数吃子棋不一样，五道棋被吃掉的棋子不会永久移除，而是回到它原来主人的手里，可以在后面的回合里再次落子。
如果手里的棋子暂时用完了，这一轮就跳过，等对方继续落子，不代表整局结束。
棋盘下满，比谁棋子多
25 个棋位全部落满棋子时，游戏结束。
数一数棋盘上双方各有多少颗棋子（不看手里剩下的），棋子多的一方获胜；一样多则为平局。
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。
