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
