Java Rubik's Cube

On the Thunkable site, "Thunkable App of the Month - July 2018" had been announced. It is an application to explain the solution of Rubik's Cube. I have a special Rubik's cube called Java Rubik's Cube. It was distributed as a souvenir at Sun Tech Days 2007 in Tokyo more than 10 years ago. I completely forgot the solution, but this app should lead me well.

Java Rubik' Cube is somewhat more difficult than general Rubik's Cubes in the first stage. When a surface is filled with the same images, they must be arranged in the same direction as in the following figure. However, after overcoming this constraint, the latter half of the solution might become rather easy.
