Rubik Resolution by PASCAL'S Method
"PASCAL'S" Method
(Placement Arêtes Sommets Centres par Algorithmes Limités)
it's a mix of
Intuitive CFOP
with phases of orientation type ZZ or Petrus
but in much simpler
STEP 1 : make 1 perfect cross + train and place 2 F2L
STEP 2 : train and place the 3rd F2L by monitoring the orientation of the edges
STEP 3 : train the 4th F2L while orienting the 2nd Cross Edges
STEP 4 : place the 4th F2L while placing the Edges of the 2nd Cross
STEP 5 : orient the Summits
STEP 6 : END OF CUBE
- STEP 1 intuitive -
make 1 perfect cross + train and place 2 F2L
(for the example, we realize the WHITE CROSS)
but for motivated people …
It is interesting to be able to make this cross of any color.
it is not as simple as it seems!
the location in the space, of each piece of the cube compared to the others,
then becomes much more delicate in the rest of the resolution.
this step is totally intuitive, no algorithm to learn by heart.
Make the cross.
to be fast, it is interesting to be able to realize this cross,
on the lower side, or if not, on the left side of the cube.
it requires to know, by heart, the normal position of the colors of the cube.
because you must never reposition the cross during its construction,
(That's a habit to take)
in short, to make the perfect cross is simple,
but it's a lot harder to do it
optimized, that is to say quickly, in a few movements.
ALWAYS less than 10 (usually 7)
the first 2 F2L (First 2 Layers)
This is to form a pair Ridge + Top
that we then place correctly in the cube
it is very intuitive and with a little habit it becomes VERY simple.
below all possible cases.
(formulas can not be learned, they must come naturally, it's easy!)
- STEP 2 intuitive -
train and place the 3rd F2L by monitoring the orientation of the edges
It's about forming the F2L pair in a classic way and then placing it
BUT
it should be done as much as possible so that there is
at least 1 YELLY ridge well oriented in U at the end of the operation
(ideally 2 or better 3)
there are 2 cases + symmetrical, elementary and intuitive
following the orientation of YELLOW Ridge on the middle slice do :
EVENT A : L'UL EVENT B : F'L'FL
if no YELLOW ridge on the middle edge
and none to 1 in front U do the event B
(formulas can not be learned, they are elementary)
- STEP 3 intuitive -
train the 4th F2L while orienting the 2nd Cross Edges
the goal is to arrive at
7 elementary and simple + symmetric EVENT
IF STEP 2 IS PROPERLY IMPLEMENTED
THE RARE CASE IS ALMOST IMPOSSIBLE
(still easy, the formulas can not be learned)
- STEP 4 intuitive -
place the 4th F2L while placing the Edges of the 2nd Cross
4 main cases, elementary and simple + symmetrical
the tracking is very easy!
we search for the middle edge
the one with the opposite color on the U side
following the classic rule
GREEN opposite BLUE | RED opposite ORANGE
(Also, the formulas can not be learned, it's very simple!)
The first and middle sides are finished!
the resolution of the last F2L
in little movement
(from 6 to 17, in general 10)
allowed also to have
THE YELLOW CROSS
ORIENTED AND PLACED
NEXT 2 PRIVILEGED CASES
- STEP 5 -
orient the Summits
the intuitive steps are over!
But this is always simple because there are very few algorithms to learn.
They are running with easy tracking
5 simple and fast cases
sometimes there is no summits well oriented, then do 1 or 2
even if there are many others, but not shorter,
it's important to use these algorithms,
because they all preserve the placement of the edges
concerns especially the case where no summit is well oriented from the start
- ÉTAPE 6 -
END OF CUBE
8 simple algorithms that correspond to 8 PLL of CFOP, the only ones to know
if no summit is well placed = PLL E
do 2 times the algorithm Aa or Ab
CUBE IS RESOLVED !
with usual less than 20 seconds are attainable !
this method does not compete with the techniques that are
CFOP Fridrich, Roux, ZZ,
when they are mastered in their entirety.
it remains nevertheless more effective than
CFOP F2L + OLL 2step + PLL 1step
AND ESPECIALLY
it is much simpler than all that
it is very intuitive in 3/4 of the resolution
there are very few algorithms to know: only 13!
they are all short and easy to execute
the tracking is very simple and logical
