## What is Spy Chess?

Set to English: Setting button -> 语言 ->English
1、 Chessboard:
1. The chessboard is 9X9 square, with 9 soldiers, 6 ministers, 2 bodyguards and 1 lord at the beginning
2. The border divides the battlefield into two parts, and the ability of a few arms is limited by the border
3. There are two fortresses in the border. The units stationed in the fortress will not be attacked and cannot attack others. It will take one step to leave the fortress. If there are units around the fortress, they cannot leave the fortress.
2、 Undercover:
1. Insertion:
At the beginning of the game, spies can be secretly planted in the other unit, and two ways can be selected:
A. Two spies are randomly placed in the [Soldier], but neither side knows which one is the spy before the spy turns against the enemy.
B. Insert a spy in the [minister], and the spy can be known by his side throughout the whole process.
The spy can be upgraded, walked and attacked by the opponent normally, and can't do any operation before the enemy's spy turns back.
2. Backwater:
It takes one step to reverse. The reverse unit inherits the skills of the previous unit and changes the camp after the flop. If the spy selected previously is [soldier], then at some time, it will require a counterattack. At this time, it will reveal the units previously installed, and of course, it may have been eaten up by itself.
3、 Advanced
Low-level chess pieces can be advanced in various ways, and have different functions after advanced

### 1/5 — 去你的

*2025-08-02*

不好玩

### 5/5 — 创新玩法

*2024-10-10*

象棋，开局双方各有一个卧底（兵／卒），卧底兵可以变为卒，卧底卒可以变成兵 ，。       可以防软件作弊，而且目前这个玩法在农村比较流行
希望您采纳这个建议，把这个玩法做到游戏里

### 3/5 — 建模很棒，但有一些小问题。

*2024-07-22*

甲 规则介绍中的文本描述晋级的方式大都为：“【大臣】击败 【士兵】骑士：【骑士】。”请问一下，这个冒号的作用是什么？
它与上下文有何关联？
        乙 规则文本中大臣的可行方向是周围8个方向，但图例和游戏中只能上下左右4个；而行刑官的情况与大臣相反。
        丙 在摄像头中调成自动，在某些时候，棋盘会自动翻转，但棋子名称却没有翻转。
        创意和建模都很好，若是有一段配乐就更好了。

### 5/5 — 哈哈哈有意思
