# Step three: SECOND LAYER

To solve second layer we use two-coloured cubes that do not have the yellow colour. In the starting position they are either on the the top or second layer, but usually at the wrong position.

We ADVISE you to begin with the cube with which you also put into the right position (on the upper face) the next cube that does not have the yellow colour. The cube in the front face is rotated (if necessary) to the face that has the same colour. In this example the purple-blue is at the right starting position and with matching colours, and the red-green one needs rotation to be put to the red face. The upper colour of this starting two-coloured cube decides on which of the two algorithms will be used for the rotations.

###### If the upper colour of the cube that we want to solve is identical to the COLOUR OF THE LEFT FACE, then we apply a different algorithm:

However, it may happen that we have a problem when the top layer is with no more two-coloured cubes that do not have the yellow colour, and we still have more unresolved cubes in second layer.

Even then we use the same, above mentioned rotations – algorithms, but with the aim to position the problematic cubes from second layer to the upper one - top layer. The choice of the algorithm is therefore the same as with positioning cubes from layer three to layer two! Having positioned the problematic cube to the upper layer, we drag it to the correct starting position and again use the rotations to put it back to the correct position (using the adequate algorithm).
