Rubik's XV

An expanded version of Jaap Scherpuis' Solution

Solve Columns 3 and 4 of the Front Side

Solve the 3rd Column

Link tile III to tile VII:		Repeat the move until tile III is anywhere in the third column (except the for bottom row)... If tile VII is directly below it, then tiles III and VII are already linked.	R C R C
		If tiles III and VII are not linked, then repeat the move until tile VII is almost on the bottom of the fourth column...	R C R C
		Do the move to transfer tile VII into the holding cell...	B R C R B R C R
		Repeat the move until tile III is almost on the bottom of the thrid column...	C R C R
		Now do the move to link tiles III and VII together...	B R C R B R C R
Link tile VII to tile XI:		Repeat the move until tile VII is anywhere in the third column (except for the bottom row)... If tile XI is directly below it, then tiles VII and XI are already linked.	R C R C
		If tiles VII and XI are not linked, then repeat the move until tile XI is almost on the bottom of the fourth column...	R C R C
		Do the move to transfer tile XI into the holding cell...	B R C R B R C R
		Repeat the move until tile VII is almost on the bottom of the thrid column...	C R C R
		Now do the move to link tiles VII and XI together...	B R C R B R C R
Link tile XI to tile XV:		Repeat the move until tile XI is anywhere in the third column (except for the bottom row)... If tile XV is directly below it, then tiles XI and XV are already linked.	R C R C
		If tiles XI and XV are not linked, then repeat the move until tile XV is almost on the bottom of the fourth column...	R C R C
		Do the move to transfer tile XV into the holding cell...	B R C R B R C R
		Repeat the move until tile XI is almost on the bottom of the thrid column...	C R C R
		Now do the move to link tiles XI and XV together...	B R C R B R C R

Solve the 4th Column

Link tile IV to tile III:		Repeat the move until tile III is on top of the third column... If tile IV is on top of the fourth column, then tiles IV and III are already linked.	R C R C
		If tiles IV and III are not linked, then do the move so that tile XV is out of the danger zone, while tile IV is in the danger zone...	R C R C
		Repeat the move until tile IV is in the holding cell...	B R C R B R C R
		Do the move so that tile III is almost on top of the fourth column...	R C R C
		Repeat the move until tiles III and IV are linked together...	B R C R B R C R
Finish the last three tiles:		Repeat the move until tiles III and IV are both on the top row... Check to make sure that the third column is still intact, while tile IV is on top of the fourth column.	C R C R
		Do the move to get tiles VIII, XII and the asterisk into the danger zone...	R C R C
		Repeat the move until the asterisk is in the holding cell...	B R C R B R C R
		Do the move to rotate tiles VIII and XII back to the fourth column...	C R C R
		Now the fourth column is finished, along with the rest of the puzzle
