Rules
Board and Setup
The board is a 5 by 5 grid. It has horizontal and vertical lines, but no diagonals.
15 soldiers fill the top three rows.
3 cannons sit in the middle of the bottom row. The middle row is empty.
Movement
On your turn, move one of your pieces one step along a line — horizontal or vertical — to an adjacent empty point.
Both cannons and soldiers only ever move one step this way. No diagonal moves, no multi-step slides.
The cannon side always moves first each round.
Capturing
Only cannons capture. Soldiers can never capture a cannon.
If a cannon and a soldier sit on the same line with exactly one empty point between them, the cannon can choose to jump that gap and capture the soldier, landing where the soldier was; the cannon can also choose not to capture it, and instead make an ordinary move.
Winning
The cannon side wins as soon as the soldiers are reduced below 4.
The soldier side wins by surrounding all 3 cannons so none of them can move at all.
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
棋盘是一个 5 列 5 行的方格网，横竖都有线，没有斜线。
15 枚兵坐满上面三行。
3 枚炮排在最下面一行的中间。中间一行是空的。
行棋规则
轮到你时，把自己的一枚棋子沿横线或竖线移动一步，走到相邻的空位上。
炮和兵都只能这样走一步，不能斜着走，也不能一次走好几步。
每局固定由炮方先走第一步。
吃子规则
只有炮能吃子，兵不能吃炮。
如果一枚炮和一枚兵在同一条横线或竖线上，中间正好隔着一个空位，炮这时可以选择跳过这个空位、吃掉这枚兵，落在兵原来的位置上；也可以选择不吃这枚兵，而选择走别的一步。
胜负条件
炮方一旦把兵吃到剩下不足 4 枚，炮方就获胜。
兵方如果把 3 枚炮全部围住、让炮一步都走不了，兵方就获胜。
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。
