Your little mission

Place every squad and fill the grid without repeating a number in a row, column or marked box. A shape can fit an empty space and still be invalid if one of its numbers conflicts with the surrounding grid.

A few helpful ideas

Check the numbers as carefully as the outline of a piece.
Try rotating a squad before ruling out a promising space.
Use already placed numbers to narrow down where the remaining squads can go.

How to play

这次的小目标

放下所有数字小队并填满棋盘，每一行、每一列和标记的小宫格内都不能有重复数字。形状刚好能塞进去，也不代表数字规则一定符合。

玩得更顺手的小窍门

观察外形时，也逐个检查小队上的数字。
遇到看似差一点的位置，先旋转小队试试。
利用已经落位的数字，缩小剩余小队的可选范围。

动动手，开始玩

点击数字小队: 选择准备摆放的一组数字。
再次点击所选小队: 旋转这组数字的形状。
点击棋盘: 在符合规则的位置放下小队。

Give every number a place to belong.
