Latch Cube II (2 Latch Faces) is a modified version of original Latch cube. It has only 2 latch faces, and others are normal 3x3x3 cube faces.
The Latch cube is a 3x3x3 cube with arrows showing which way you can turn the face. Turn as the arrow goes.
It's a simple idea and built with simple structure. Black arrows turn anti-clockwise and white arrows turn clockwise. When black and white arrows on the same face, the face turning is locked. This is the most challenging 3x3x3 cube puzzle ever!
