Watermelon Chess · Twelve Pieces · 西瓜棋·十二子

Twelve pieces on twenty-one points, and captures start while you are still placing. The board is crowded from the opening move.

二十一个点摆十二枚子，而且放子阶段就能提子——从第一手起，盘面就是挤的。

十二子布阵，围住无气棋

Build with twelve pieces and surround groups with no air

玩法要点

Place twelve pieces each, capturing surrounded groups even during placement; start stepping along lines only after all reserves are placed.
Remove a rival piece or connected group when it has no adjacent empty point.
Reduce the rival to one piece to win; eighty consecutive moves without capture draw.

The board has 21 points. Players take turns placing twelve pieces on empty points.

A placement can already surround and remove rival pieces, so the board does not need to fill first.

After both hands are empty, take turns moving one piece along a line to an adjacent empty point.

A piece cannot jump or land on an occupied point.

After placing or moving, remove a rival piece or joined group when there is no empty point beside it.

Your own pieces need an empty point beside them too.

Reduce the rival to one piece to win — you don't need to remove the last one.

The game is a draw after 80 moves in a row without a removal.

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.

棋盘有 21 个棋点。双方轮流把十二颗棋子放到空点上。

这时也能围住并拿走对方的无气棋，所以棋盘不必同时放满。

双方手里的棋子都放完后，轮流沿线走一颗棋子到相邻空点。

不能跳过棋子，也不能走到有棋子的点上。

放子或走子后，对方一颗棋或一群连在一起的棋，旁边没有空点，就一起拿走。

自己的棋也要留一口气，不能把自己围死。

把对方棋子拿到只剩一子，就算赢了，不用拿到一个不剩。

连续 80 步都没有拿走棋，这一局算和。

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。
