Neihuang Ge Fang Qi · 内黄割方棋
The board fills up peacefully, then each side pulls a piece and the squares begin. Everything you built is suddenly a target.
先安安静静把盘填满，然后各拔一枚，成方开始算数——你刚摆好的阵，转眼全是靶子。
先布后走，成方连五吃子
Place, then move; squares and rows capture.
玩法要点
- 棋盘：5×5 交叉点，共 25 个棋位
- 棋子：黑方 13 枚、白方 12 枚
- 获胜：把对方棋子吃到三颗或更少
Quick start
- Fill the board without capturing; White removes a black piece, Black removes a white piece, then White moves first.
- Move one step horizontally or vertically; a 2×2 square captures one and a line of five captures three, with no protected pieces.
- Win by reducing the opponent to three pieces or fewer; if you block them, remove an eligible piece of your own to free a move.
快速上手
- 轮流布满棋盘，布子不吃；白方先拔黑子，黑方再拔白子，然后白方先走。
- 沿横竖线走一格，四子成方吃一、五子成线吃三，无铁子保护。
- 吃到对方只剩三子或更少获胜；堵住对方须拔己子让路。
Rules
Place First, Then Move
The board is a 5×5 grid of intersecting lines, 25 points in all.
Black places first, then players alternate placing until the board is completely full — no captures happen during placement, even if a shape forms while placing.
Pulling: Each Side Removes One Piece
Once the board is full, White removes any one of Black’s pieces, then Black removes any one of White’s — unlike some fang qi variants where only one side pulls, Neihuang has both sides pull once each.
There is no restriction on which piece can be pulled — even one currently sitting inside a formed shape.
Movement Phase: One Step at a Time
Once both sides have pulled, White moves first, then players alternate: each turn, move one of your own pieces one step along a line to an adjacent empty point (no diagonal moves, and you can’t move onto an occupied point).
Yifang: A 2×2 Square
A 2×2 block of your own pieces freely captures one enemy piece.
Yizou: Five in a Row
Five of your own pieces in a straight line, horizontal or vertical, freely captures three enemy pieces.
Capture counts stack if one move completes both shapes at once.
No Protection on Captures or Pulls
Unlike several other fang qi variants, Neihuang Ge Fang Qi has no "iron piece" protection — any of the opponent’s pieces, even one currently part of one of their own formed shapes, can be chosen for a pull or a capture.
Remove an Own Piece to Make Room
After a move and any captures, if the opponent has no moves, the player who just moved must remove one own piece that gives the opponent a legal move.
The opponent moves after that removal. Any own piece may be chosen if removing it makes room.
Win by Reducing the Opponent to 3 or Fewer
Reduce the opponent to 3 pieces or fewer to win. Even the smallest shape, Yifang, needs 4 pieces.
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
先布子，后走子
棋盘是 5×5 的纵横线交叉，一共 25 个棋位。
黑方先落子，之后双方轮流落子，直到棋盘布满为止——布子阶段不吃子，就算落子时凑出了图形，也不会立即生效。
拔子：双方各拔对方一子
棋盘布满之后，由白方先拿掉黑方任意一颗棋子，接着黑方也拿掉白方任意一颗棋子——不像有的方棋只拔一次，内黄是双方各拔一次。
拔子没有限制，哪怕这颗棋子正摆在"一方"或"一走"的图形里，照样可以被拿掉。
走子：单步移动，仍可吃子
双方都拔完子后，由白方先走，之后交替：每次选一颗自己的棋子，沿直线移动到相邻的空位（不能斜着走，也不能走到已有棋子的位置）。
一方：2×2 的方块
4 颗己方棋子摆成一个两两相靠的口字形，就能任意吃掉对方一颗棋子。
一走：横竖连成五子
5 颗己方棋子横着或竖着连成一线，就能任意吃掉对方三颗棋子。
如果一步棋同时摆出"一方"和"一走"，吃子数可以累加。
吃子和拔子都没有保护
和不少方棋变体不一样，内黄割方棋没有"铁子"这种保护——不管是拔子还是吃子，对方任意一颗棋子（哪怕正处在它自己摆成的图形里）都可以被挑中拿走。
对方无路可走时，拔己子让路
走子完成（包括吃子）后，如果对方一颗棋子也走不了，刚走的一方必须拔掉自己一颗能让对方重新走动的棋子。
拔完后才轮到对方走。任意己子都可选择，只要拔掉后能让路。
吃到对方三颗或更少即获胜
把对方的棋子吃到只剩三颗或更少，就获胜。因为最小的“一方”也需要四颗棋子。
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。
