The standard Rubik's secret is just in the blink of an eye

The secret below will help you successfully stack Rubik (3x3) in just a short time .

Rubik was a puzzle game invented by Professor Ern Hungary Rubik of Hungary in 1974. The standard version of Rubik is a cube next to 3x3 with 6 colors in 6 faces: red, yellow, orange, green, blue Yang and white. The edge length of cube Rubik standard is about 5.7cm.

Rubik has a simple way of playing but . super difficult, like solving a problem. The game begins by shuffling the colored squares on Rubik and the player's task is to find a way to re-arrange Rubik to its original shape with 6 uniform color faces.

For beginners, if there is no method, they will almost never solve the Rubik problem. In the world today, the fastest Rubik ranked is Mats Valk with a record of 5.55 seconds at Melbourne Cube Day 2013.

Just remember the algorithms and formulas, Rubik is just a "little story".

Rubik's nature is to use permutation algorithms to succeed . Each standard Rubik has 43 billion different permutations. If you consider each Rubik's cube to be a permutation and arrange it into a curved surface, this amount is enough to cover the Earth's surface 256 times.

To successfully solve a standard Rubik block (3x3), there are many different methods. Some quick rotation methods developed by Jessica Fridrich, Philip Marshall or Ryan Heise can help solve Rubik only after 40-65 turns.

However, this method is usually only used for long-term players, because the algorithm is difficult and even a lot (with Fridrich method, you have to remember 120 different algorithms).

The most common and popular way to solve Rubik's suit for all subjects is the method of David Singmaster - an English mathematician.

Simply put, it is understandable that this is the way Rubik ranks each floor. For the first floor, the player needs to place a standard cross on one side (the color of the top of the cross coincides with the face color and the color of the 4 surrounding faces).

After that, the player ranked 4 blocks in the right corner of their position to complete the first floor. During the folding process, it is necessary to maintain the position of the cross that has been folded.

For the second floor, the work begins to be more complicated. Players must place 4 corners of this floor in the right position without breaking the structure of the bottom floor that has just been completed.

The third floor is the most difficult stage in solving a Rubik block. For this level, players must remember a lot of algorithms. One of the typical ways is to fold so that the end face is uniform (even if the blocks are in the wrong position).

Next, use the formula to swap places so that 4 small blocks in the corner are in the right place without changing the structure that has been arranged in the lower floors. Finally, the player finishes the middle edge in the correct position to complete.
