Everyone please post their average time of doing it at least doing it a few times
Put how fast you did it each time(or just give us the average)
Then tell us how many times you did it
DdKiller
My average is about 45 seconds =( I'm slow compared to my friends. They're averages are about 30 seconds.
My best is 1.17 but most of my friends are at about 50 seconds.
Where can you buy Rubik's Cube 7x7x7 in the Philippines?
You can buy Rubik's cube in the Philippines. You do not need to travel far, for you can try the malls near your place, or if you want me to be more specific, try National Book Stores or any toy store within any mall. & then ask a customer service personnel.
How do you solve a Rubik's Cube faster?
Here's one method that may impress some of your friends who can't figure it out: get a cube that is already solved. Videotape yourself quickly and frantically unsolving it. Go as long as you like. Then figure out how to play the video backwards. Be sure you don't do anything while taping that will make your trick obvious, like someone casually walking bakwards through the frame, or "pouring" a liquid from a glass back into the bottle. OK, people will catch on, but some may take a little extra time.
The Rubik's Cube was first oringinaly called the "Magic Cube" by it's inventor Erno Rubik
What is the fastest time for an 11 year old kid to solve a Rubik's cube?
As of my last update, the fastest recorded time for an 11-year-old to solve a Rubik's Cube is 5.69 seconds, achieved by a young prodigy named Max Park in 2017. However, records can change frequently due to ongoing competitions, so it's advisable to check the World Cube Association or recent news for the latest updates on youth records.
What is the record for the largest Rubik's Cube?
Hundreds of competitions are organized each year in many different countries where speedcubers can compete against each other. The record times set in those events are known as 'official world records'.
The official world record as of 3/07/2011 is 6.24 set by Australian cuber Feliks Zemdegs at the Kubaroo Open 2011 competition.
As for unofficial world records, there's no certain answer. Many cubers post videos to YouTube claiming they achieved this or that time, so it is very hard to keep track of any unofficial world records.
Also, it might be possible that it unofficial world records are not true. Official world records are always true and valid, because there are judges at every competition.
How do you solve two sides of a Rubik's Cube?
I used this series of video's on youtube.com:

I highly recommand to first learn how to solve a 3x3 Rubik's Cube, because at some point of the 4x4 you have to solve it the way like a 3x3, and that part is not in the video or at the website.
How do you solve a 1x1x1 Rubik's Cube?
As you are reading this you will realize it is not complete, as I am not finishing this at once and will add to it every so often. Note: this is only for regular 3x3 rubiks cube. Not Sudocube, special patterned ones, or different dimensions of cubes however this is good help for other sizes of cubes.
The first thing you must realize is how a rubik's cube works. There are 26 cubies that seem to turn. however it is important to know that the centre cubes never move. They are fixed. These are called centre pieces, and there are 6. Yes, they turn around an axis but never move.Upon examination you will realize that not all cubes are the same. There are also corner pieces, which there are 8 of. Each of them have three stickers on them and are a part of two separate faces. Then there are edge pieces, of which you will find 12, which have two stickers on each. I recommend taking apart your cube, examining how it works. To do this, simply turn one face (a side, with 9 cubes) 45 degrees. Then, with your finger, pry up one of the edgepieces that was moved. Continue from there. Pull the rest apart. Putting it back together isn`t very hard, just remember to put it in the solved position. This is because chances are when you don`t, 12-1 odds are it can`t be solved, because there are some permutations (positions) that are normally impossible. (as a side note, don`t complain how hard it is to put back together because the 4x4, 5x5, and on, are much harder).
Do not skip reading that. It is important. This is also important or you will not understand the rest of this. Heres another term: an algorithm is a set of moves. You might say, aaaaah, so if I learn this magical algorithm, I can solve the cube? Well, not quite. You see, there are over 43 quintillion permutations of the cube (43,000,000,000,000,000,000+). Right? So one set of moves cannot solve it. Instead, there are several steps that orient (place each cube in the right place) and permute (solve the cubes completely so they are in there spot facing the right way in relation to the others). But there are many algorithms that vary slightly in each step depending on the permutation of the cube. So as I walk you through these steps and algorithms, you are going to need to know the following things. To simplify the algorithmns, here are the letters that will stand for each face: U (up face, on top); D (down, bottom); F (front, so facing you); B (back); L (left); and R (you guessed it! Right). So just so you know, that is U, D, F, B, L, R. Don`t ask which goes with which colour because none do. It is just how you are holding it at one time. Now you need to know the different types of turns: the quarter turn and the half turn. The quarter turn is a turn of a face one quarter of the way around clockwise, or 90 degrees. Then of course a half turn is a turn of a face halfway around axis (180 degrees, and it doesn't matter which way you turn it. However, if you want to get very fast, this is something you should think about). There is no need for a three-quarter turn because it can be shown and done as a backward quarter turn, and of course a full turn is not a move at all. In algorithms, a quarter turn is represented by just the letter of the face. So F alone means turning the front face clockwise a quarter turn (90 degrees). Or for example FRU means turning the front face a quarter turn, then the same for the right face and up face - but note: it MUST be done in the order it is in the algorithm or it will never work. A half turn is notated the same exept there is a 2 after the letter. So F2 means turn the front face a half turn (or two quarter turns). All that's left now is the counterclockwise quarter turn, which is indicated with an apostrophe after the letter. So F' means turn the front face counterclockwise a quarter turn. That is all the notation you will need to know for now, and for these instructions. Well that 's enough of that. Yes, yes, how to solve a 3 by 3.
STEP 1: The first layer.
DO NOT skip to here. There are no algorithms for this layer. It is intuitive (you learn it by doing it). However, you still need to read the above paragraphs, as it may help you. By the first layer, that means completely solving the U face (the top 9 cubes). Most cubers start with the same face every time and its usually the white face. But irregardless of what you chose, the procedure is the same. You must first make the cross on the top. This means that the four edge pieces are solved on the first layer (and of course are on the same side as their corresponding centre piece). How to do this however is hard to explain, as it is intuitive.
go to the following page:
http://www.corpusvile.com/docs/rubikscube/1.jpg).
This is what you are aiming for. The cross is formed, but I want you to try and find the mistake in the picture.
No, no it isn't because the rest of the stickers were removed. If you look at your cube, solved or not, you will see that this cube is messed up because the white, blue and red centre pieces are in the worng places. Blue and red appear to have been switched. This is something you are going to need to remember, the order of the colours. With white on top (and of course yellow on the bottom), the colours are, starting at blue moving left: blue, red, green, orange. This may seem obvious but it is a good thing to remember, especially if you want to learn to solve a cube that is even, like 2x2, 4x4, etc.
How many possible combinations are there on a Rubik's Cube?
There are 8 corner pieces with 3 orientations each, 12 edge pieces with 2 orientations each, giving a maximum of 8!·12!·38·212 positions. This limit is not reached because:
- The total twist of the cubes is fixed (3)
- The total number of edge flips is even (2)
- The pieces have an even permutation (2)
This leaves 8!·12!·37·210 = 43,252,003,274,489,856,000 or 4.3·1019 positions.
Total Positions
There are exactly 43,252,003,274,489,856,000 permutations, which is approximately forty-three quintillion. The puzzle is often advertised as having only "billions" of positions, as the larger numbers could be regarded as incomprehensible to many. To put this into perspective, if every permutation of a 57mm Rubik's Cube were lined up end to end, it would stretch out approximately 261 light-years.

What does w in a 3x3x3 Rubik's Cube algorithm mean?
it is a series of turns you do on a Rubik's cube. EXAMPLE: the algorithm "R Ui D" means turn the right side clockwise, turn the upper side counterclockwise, and turn the "Down" side clockwise. the I means inverted, or counterclockwise.
Where in brisban can you bye a 2 by 2 Rubik's Cube?
Well, depends which rubik's cube. If you just want a 3x3x3... go to westfields eastegardens big w... or any big w... i think. but definetly in eastgardens big w u can get a 3x3x3
Where can you buy the rubik cube clock?
One of the major sources is the US Chess Federation, who publish a catalog in conjunction with their magazine Chess Life. There are specialty shops that cary clocks, but not with any great variation in models. If you visit a major chess tournament site, there will often be vendors present, but again not mauch variety.
(see the links for an online source and the Ebay category)
How do you break into a Rubik's Cube?
1.) twist one side (it doesn't matter which one) so the corners stick out. 2.) use a flat screwdriver to pry it out. (put it under the edge piece and pry toward the rotated side)
3.) take the corners out through the gap you left.
4.) from then on, it kinda falls apart. Just help it.
NOTE: the centers don't come out.
I ALSO THINK YOU WILL NEED THIS INFO:
To put it back together, do:
1.) fit one edge piece in their right place between the centers.
2.) fit the other edge piece in it's right place next to the one you just put in.
3.) slide the right corner in it's place in between the two edges you put in.
4.) continue doing this until you are almost done. MAKE SURE AN EDGE PIECE IS LAST! fit the last edge piece in the same way you took it out. it may help to rotate it the way i said above.
IMPORTANT!!!!!!!!!!!!! PUT IT BACK TOGETHER SOLVED! IT MIGHT BE IMPOSSIBLE TO SOLVE IF YOU PUT IT BACK TOGETHER RANDOMLY!
Hope I helped.
How do you solve a 2x2x2 Rubik's Cube blindfolded?
There is no way to cheat, feel or use math to get through a rubik's cube blindfolded. There is only one way to do it: you have to have a great memory.
How can you solve a Rubik's Cube faster?
You lubricate it with a silicon spray that you can buy at a hardware store or auto shop.Do not use petrolium product because they will just eat the cube.Another thing to consider is get a differt type of rubiks cube which you can buy at cube4you.com.
How many sides does a Rubik cube have?
There are Six independently rotating joints. The whole cube is held together by these. Colored centers are attached to the joints. The edges are held down by the centers. And the corners are held in buy the edges.
How do you do the rubiks cube magic trick?
The illusion is actually quite simple. All you need is a solved rubik's cube and a few extra stickers. take any solved side (we'll say yellow). stick a few colors on that yellow side so you have a fully solved cube except for the yellow side which looks unsolved. Now you should do a few moves and memorise them. Show the audience the entire cube on each face so it looks entirely scrambled. Hold the cube to where the side that will always be unsolved is facing your audience. Now reverse the moves that you memorised acting like you're trying to solve the cube. Once the cube is solved on each side except for the side facing the audience, act like you give up on the cube and proceed to tell the audience there is an easier way. After doing this toss the cube into the air and when you catch is make sure the side that is unsolved is facing down or towards you. The audience will be amazed as they've just seen you solve a rubik's cube by simply tossing it into the air. Show some sides of the cube by tilting it but not tilting it too far where they'll see the unsolved side.
Make sure you practice this a few times on your own to make it look more authentic.
Have fun with this mind blowing illusion!
Dayan ZhanChi is the cube is would personally refer to use as this cube works like a magic. It just requires a slight push to move. I use this mostly and is very satisfied with it.
What math is used when solving a rubik's cube?
MATHEMATICS OF THE CUBE
The center pieces of each face are always in the same relationship to each other.
Therefore, the number of ways the other pieces can be arranged in relation
to them (ie the possible arrangements of the cube) is:
Total possible arrangements = (possible arrangements of Corner Pieces) x (possible arrangements of Edge Pieces).
Possible Arrangements of Corner Pieces:
There are 8 Corner Pieces. Therefore, the possible different arrangements of them is 8! (ie 8x7x6x5x4x3x2x1) = 40320.
Each Corner Piece has three different orientations, so this must then be
multiplied by 3 to the power 8 (ie 3x3x3x3x3x3x3x3) which equals 6561.
However, with the actual cube, once the second from last Corner Piece is placed, the last piece can have only one automatic orientation so this should be divided by 3 (effectively 3 to the power 7) which equals 2187.
Thus, total possible arrangements of Corner Pieces = 40320 x 2187 = 88,179,840.
Possible Arrangements of Edge Pieces:
There are 12 Edge Pieces. Therefore, the possible different arrangements of them is 12! (ie: 12x11x10x9x8x7x6x5x4x3x2x1) = 479,001,600. However, with the actual Cube (and unlike Corner Pieces) it is impossible to exchange just two Edge Pieces, so once the third from last is placed, the remaining two can have only one possible arrangement, so this total must be divided by 2, which equals 239,500,800.
Each Edge Piece has two different orientations, so this must then be multiplied by 2 to the power 12 (ie 2x2x2x2x2x2x2x2x2x2x2x2) which equals 6561. However, with the actual cube, once the third from last Edge Piece is placed, although the last two pieces will be in fixed positions, one can be reoriented but the last will always have a fixed orientation in relation to it. So this must be divided by 2 (effectively 2 to the power 11) which equals 2048.
Thus, total possible arrangements of Edge Pieces = 239,500,800 x 2048 = 490,497,638,400.
So - Total Possible Arrangements of Rubik's Cube = (possible arrangements of Corner Pieces) x (possible arrangements of Edge Pieces) = 88,179,840 x 490,497,638,400 = 43,252,003,274,489,856,000.
Roughly speaking, 4.3 times 10 to the power 19.
in simple yes, because it uses several mathematical algorithms.
Where can you get a 11x11 rubik's cube?
wal-mart, toysRus, walgreens, anywhere that sells rubiks cubes
A Rubik's cube is a puzzle in which there are miniature cube-like modules arranged in a cubic fashion. The Rubik's cube was invented in 1974 by Erno Rubik of Hungary, who gave it the modern name of Rubik's cube. It was first called the Magic Cube, and it won the German Game of the Year in the puzzles category. The most common one is Rubik's Cube has 27 mini cubes, with edges of 3 cubes each. It is possible to disassemble this cube by rotating a side 1/8 of a turn and using a screwdriver or other flat object to wedge out the edge piece. However, solving a Rubik's cube in this manner is usually known as cheating. It is very useful to disassemble the cube and apply petroleum jelly to the inner tabs of the mini cubes, and also to any other surface that is exposed to friction. This lubricates the cube so that you can solve it faster. It is still a popular and challenging puzzle to this date.
Which way is down inverted on a Rubik's cube?
it depends on how you hold it. however you hold it, the lower side is down. if it is just down than it is clockwise, if it is down inverted, then it is counterclockwise.
