Rubik’s Cube 1980s craze and Move Notation

1980s Cube craze

After the first batches of Rubik’s Cubes were released in May 1980, first sales were small, yet Ideal started a tv marketing campaign in the middle of the year which it supplemented with paper adverts. At the end of 1980, Rubik’s Cube won a German Video game of the Year unique honor as well as won similar honors for best toy in the UK, France, and also the United States. By 1981, Rubik’s Dice had become a craze, as well as it is estimated that in the period from 1980 to 1983 around 200 million Rubik’s Cubes were marketed worldwide. In March 1981, a speedcubing champion arranged by the Guinness Publication of Globe Records was held in Munich, and also a Rubik’s Dice was depicted on the front cover of Scientific American that same month. In June 1981, The Washington Article reported that Rubik’s Dice is “a challenge that’s moving like fast food right now … this year’s Hoola Hoop or Bongo Board”, and by September 1981, New Researcher noted that the dice had “captivated the interest of children of ages from 7 to 70 all over the globe this summertime.”

As the majority of people could solve just one or 2 sides, numerous publications were released consisting of David Singmaster’s Notes on Rubik’s “Magic Dice” (1980) and Patrick Bossert’s You Can Do the Cube (1981 ). At one phase in 1981, 3 of the top 10 best selling books in the United States were books on resolving Rubik’s Cube, and the very popular book of 1981 was James G. Nourse’s The Easy Option to Rubik’s Cube which offered over 6 million copies.  In 1981, the Museum of Modern Art in New York showed a Rubik’s Dice, and also at the 1982 Globe’s Fair in Knoxville, Tennessee a six-foot Dice was put on display screen.  ABC Television also developed an anime program called Rubik, the Impressive Dice. In June 1982, the First Rubik’s Cube Globe Championship took place in Budapest and also would certainly end up being the only competitors recognized as authorities until the championship was revived in 2003.

In October 1982, The New York Times reported that sales had fallen and that “the craze has actually passed away”, and also by 1983 it was clear that sales had actually dropped. However, in some Communist nations, such as China and also USSR, the fad had begun later on and demand was still high due to a scarcity of Cubes.


Robik’s Cube Move Notation

Numerous 3 × 3 × 3 Rubik’s Cube lovers use a symbols established by David Singmaster to denote a series of actions, described as “Singmaster notation”. Its loved one nature permits formulas to be written in such a manner in which they can be applied despite which side is designated the leading or exactly how the colours are arranged on a specific cube.


F (Front): the side presently encountering the solver

B (Back): the side opposite the front

U (Up): the side over or in addition to the front side

D (Down): the side opposite the top, beneath the Dice

L (Left): the side directly to the left of the front

R (Right): the side directly to the right of the front

ƒ (Front two layers): the side encountering the solver and the equivalent middle layer

b (Back 2 layers): the side opposite the front as well as the matching center layer

u (Up two layers): the top side and the corresponding middle layer

d (Down 2 layers): the bottom layer and the matching middle layer

l (Left two layers): the side to the left of the front as well as the matching middle layer

r (Right 2 layers): the side to the right of the front as well as the corresponding middle layer

x (revolve): turn the entire Cube on R.

y (turn): turn the whole Cube on U.

z (rotate): revolve the whole Cube on F.

When a prime sign (′) adheres to a letter, it denotes an anticlockwise face turn; while a letter without a prime sign signifies a clockwise turn. These instructions are as one is taking a look at the specified face. A letter complied with by a 2 (periodically a superscript 2) denotes two turns, or a 180-degree turn. R is right side clockwise, yet R ′ is right side anticlockwise. The letters x, y, and also z are used to suggest that the entire Cube ought to be turned about among its axes, representing R, U, and F turns specifically. When x, y, or z are primed, it is an indication that the dice need to be rotated in the opposite instructions. When they are settled, the cube needs to be rotated 180 degrees.


The most common discrepancy from Singmaster symbols, as well as actually the current main requirement, is to make use of “w”, for “large”, as opposed to lowercase letters to represent steps of 2 layers; thus, a relocation of Rw is equivalent to one of r.

For approaches making use of middle-layer turns (especially corners-first methods), there is an usually accepted “MES” extension to the notation where letters M, E, and S represent middle layer turns. It was utilized e.g. in Marc Waterman’s Formula.

M (Center): the layer in between L as well as R, turn direction as L (top-down).

E (Equator): the layer between U as well as D, transform direction as D (left-right).

S (Standing): the layer between F and also B, transform instructions as F.

The 4 × 4 × 4 and also bigger dices utilize an extended symbols to describe the extra center layers. Typically talking, uppercase letters (F B U D L R) refer to the outermost sections of the dice (called faces). Lowercase letters (f b u d l r) describe the insides of the cube (called pieces). An asterisk (L *), a number in front of it (2L), or more layers in parentheses (Ll), indicates to turn both layers at the same time (both the internal and also the external left faces) For instance: (Rr)’ l2 f’ means to transform both rightmost layers anticlockwise, then the left inner layer two times, and afterwards the inner front layer anticlockwise. By extension, for dices of 6 × 6 × 6 and larger, actions of three layers are notated by the number 3, for instance, 3L.


An alternative symbols, Wolstenholme symbols, is developed to make memorizing sequences of moves much easier for beginners. This symbols utilizes the same letters for faces except it changes U with T (top), so that all are consonants. The key distinction is using the vowels O, A, and also I for clockwise, anticlockwise, and also two times (180-degree) turns, which results in word-like series such as LOTA RATO LATA ROTI (comparable to LU ′ R ′ UL ′ U ′ RU2 in Singmaster symbols). Enhancement of a C implies rotation of the entire dice, so ROC is the clockwise turning of the cube around its ideal face. Center layer steps are represented by including an M to corresponding face step, so EDGE indicates a 180-degree turn of the center layer adjacent to the R face.


One more notation appeared in the 1981 publication The Straightforward Service to Rubik’s Cube. Singmaster notation was not extensively recognized at the time of publication. The faces were named Leading (T), Base (B), Left (L), Right (R), Front (F), and Back (P), with + for clockwise,– for anticlockwise, and 2 for 180-degree turns.


An additional notation appeared in the 1982 “The Suitable Option” publication for Rubik’s Vengeance. Horizontal planes were noted as tables, with table 1 or T1 beginning at the top. Vertical front to back airplanes were kept in mind as publications, with book 1 or B1 beginning with the left. Vertical delegated appropriate planes were kept in mind as windows, with window 1 or W1 starting at the front. Using the front face as a referral sight, table actions were left or right, publication actions were up or down, as well as home window actions were clockwise or anticlockwise.
