Small Diagonal-Square · Placement · 小斜方棋·布子

The nine-point blockade with the opening in your hands: place all six pieces first, then try to freeze your opponent solid.

九点围堵，开局由你来摆：六枚子先落定，再想办法把对方冻住。

先轮流摆完六子，再走子围堵

Place all six pieces in turn, then move and blockade

玩法要点

Take turns placing reserves on empty points; movement starts only after all reserves are placed.
Move along a line to an adjacent empty point, without jumping or capturing.
Win by leaving the rival with no legal move.

The board is a 3x3 grid of nine points, with a diamond linking the midpoints of its four sides — 9 points in all.

The placement version has no fixed opening: each side's 3 pieces all start in hand, and play begins on an empty board.

On your turn, take a piece from the rack and set it on any empty point.

Sides alternate until all six pieces are on the board. You cannot move a placed piece during this phase.

The board is small, so placement matters even more — a poor spot can get you boxed in at the opening.

Once all six pieces are down, movement begins. Pick one of your pieces and move it one step along a marked line into an adjacent empty point.

You cannot land on an occupied point or jump over another piece. Nothing is ever captured.

On the opponent's turn, if not one of their pieces can move, you win.

With only 3 empty points on the whole board, a game can be decided in a few moves.

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.

棋盘是一个“田”字（三横三竖九个点），四条边的中点之间再连成一个斜口菱形，一共 9 个棋点。

布子版没有固定座子：双方各 3 枚棋子一开始都在手里，从空棋盘开始摆。

轮到自己时，从棋子架上取一枚棋子，放到棋盘任意一个空点。

双方轮流放，直到六枚棋子全部上场。摆子阶段不能移动已经放下的棋子。

棋盘小，摆子位置尤其关键，位置没选好很容易一开局就被围死。

六枚棋子全部上场后开始走子。挑一枚自己的棋子，沿连线走一步进入紧挨着的空点。

不能走到有棋子的点上，也不能跨过别的棋子。这款棋不吃子。

轮到对方走子时，如果对方一枚棋子都动不了，你就赢了。

全盘只有 3 个空点，几步之内就可能分出胜负。

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。
