1, SQ 1 (cube, but the disturbed irregular sector is difficult to recover without prompting);
2. Zongzi Rubik's Cube (actually a regular tetrahedron, divided into one with the same color and one with four colors. Four colors are several times more difficult than the same color, and they are all irregular masks after being disturbed. Even if the four colors are familiar with the third-order reduction, they should find another way);
3.SSQ 1 (actually, the middle layer of SQ 1 continues to split in two), so there is no absolute reference to the median tangent, and because there is no median tangent, the technique will be interrupted when turning, leading to confusion in the Rubik's cube.
The Rubik's Cube, also called Rubik's Cube, was first invented by Professor Ern Rubik of Budapest Institute of Architecture in 1974. Rubik's cube is an extreme hand tour. Rubik's cube is called Rubik's cube in Taiwan Province province and twisted dice in Hongkong.
Rubik's cube refers to a narrow third-order cube. The third-order Rubik's cube is usually a cube, made of elastic hard plastic. The racing game is to disrupt the Rubik's cube and then restore it in the shortest time. As of 20 17, 12, the official world record of the third-order Rubik's Cube was held by SeungBeom Cho (? ) 4.59 seconds (single time).
Broadly speaking, Rubik's cube can refer to all kinds of geometric bodies that can be disturbed and restored by rotation.
The Rubik's Cube, together with Huarong Road and Indie Diamond Chess, is called the three wonders of the intellectual game world by foreign intelligence experts, and its popularity can be called the miracle of the intellectual game world.
