Step two: FIRST LAYER

In this step you need to pay attention to the other two colours that stand by the white corner cube and by the sides of identical colours. The colour of the central cube in a face defines the colour of that face and the position of these colours is unchangeable!
If the white cube is on the upper face (and if it is necessary), we drag it to the appropriate angle of matched colours and to the starting position.

The starting position is: UPPER FRONT RIGHT ANGLE.

There are three possibilites to position the white cube: to the right, to the front face and up. According to that, we must apply appropriate moves which will be shown now.

positioning the white cube

These same algorithms are applied to the white corner cubes when they are in the lower side, with the aim to drag them to the upper side. We are talking about the cubes whose starting position is at the wrong place, and therefore need to be dragged out and put at their correct position.
A D V I C E : always start dragging out the cubes by putting the right cube at that position, with that action you will save at least three steps, i.e. your Rubik's cube will be solved faster. The following video illustrates this action:

Finally – the first layer is assembled with the correctly positioned side colours.
