The Trap Extras

A third way to handle swapped cubies configuration. (not committed to the 'Sledgehammer'.)

This is a 'tricky' configuration that makes the Cube impossible to solve.

The player may not realize that the two seemingly swapped cubies RY and YB are not the actual problem. The real issue lies with the cubies OY and YG, which are placed in the wrong positions, making it impossible to solve the Rubik's Cube.

In this case (on the layer 3) only 2 out of 4 positions are available for each cubie. That because choosing the wrong position, the relative position (between cubies), becomes not correct.
(For example: going clockwise, the order of the last 3 edges should be RB, RY, BY )

The strategy

We know a simple rotation is a solution. This time the rotation will be implemented in a different way that allows to put all the edges in place one shot

move each edge from its current position to the position of its adiacent edge.

(Left or right depend on the initial orientation)

1)	U R	Place the cubie YG into the workbench and remove it from layer 3.
2)	U R'	Place the cubie YG into its final position And remove OY from workbench.
3)	U R	Replacement of the cubie RB with the cubie OY.
4)	U2 R'	Replacement of the cubie OY with the cubie YG.
