这套积木由7个木块组成。这些木块具有相同的颜色和外部轮廓，唯一不同的点是其内部的凹面。

A set of seven wooden blocks. Each piece is characterized not by its color or external shape, but by a concave.

每套积木中包含三种形状的木块：原始的立方体（2个）、被削去四分之一个球体的立方体（4个），以及一个带有半圆切口的长方形体块（1个）。

The set consists of three shapes: two pieces in their original cubic form, four pieces with the corners chipped off in the shape of a quarter of a sphere, and one rectangular piece with a semicircle cutout.

随着立方体的不断堆叠，不仅其外部轮廓会发生变化，其内部也开始产生不一样的空隙。

As the cubes are stacked, not only do the outer contours of the cubes change, but also the inner outlines start to create voids.

除了纵向堆叠，这些木块还可以水平地放置，当积木以立体的方式排列，其内部的空隙将如洞穴一般连接起来。使用越多的木块，就会创造出越多的“留白”。

The pieces can be placed horizontally, not just stacked up, or if arranged three-dimensionally, the hollow voids connect like a cave. The more pieces are added, the more emptiness is created.
