🦠 同化棋Infection Chess
在线同化棋：7×7 棋盘上，棋子可以走到相邻一格“复制”出一颗新子，也可以跳两格“移动”过去。落点周围 8 格内的对方棋子会全部被同化成你的颜色。棋盘填满或一方无子可走时，棋子多的一方获胜。可选障碍布局、先后手和电脑难度，也能双人同屏对战。Infection Chess online: on a 7×7 board a piece can step to a neighbouring square to clone itself or leap two squares to move there. Every enemy piece touching the landing square is converted to your colour. When the board fills up or a player cannot move, whoever has more pieces wins. Choose blocked-square layouts, who plays first and the computer level, or play two players on one screen.
先点自己的棋子，再点目标格：绿色格是相邻一步（复制），橙色格是隔一格跳跃（移动）。Tap one of your pieces, then a target: green squares are one step away (clone), orange squares are a two-square jump (move).
玩法说明与常见问题How to play & FAQ
「同化棋」怎么玩？How do I play Infection Chess?
每回合选一颗自己的棋子：走到周围一圈（含斜向）的空格，原来的棋子保留，相当于多了一颗；跳到外面第二圈的空格，原来的棋子离开。落子后，新位置周围 8 格内所有对方棋子都变成你的颜色。一方无路可走时，剩下的空格全部归还能走的一方，然后比较数量。Each turn pick one of your pieces: moving to an empty square in the ring around it (diagonals included) keeps the original, so you gain a piece; jumping to the second ring moves the piece. After landing, every enemy piece in the eight squares around the new spot turns into yours. If a player has no legal move, the remaining empty squares go to the other side and the pieces are counted.
复制和跳跃哪个更好？Is cloning or jumping better?
一般来说复制更稳，因为不会在原地留下空洞；跳跃适合深入对方阵地一次同化很多棋子，但留下的空格可能被对方利用。Cloning is usually safer because it leaves no hole behind; jumping is good for diving into a crowd of enemy pieces, but the gap it leaves can be exploited.
灰色格子是什么？What are the grey squares?
是障碍格，不能放子也不能经过。不同布局会改变开局的走法。They are blocked squares — nothing can land there. Different layouts change how the opening plays.
