You got it right ... today we talk about the Rubik's cube, originally known as the magic cube.
The puzzle was patented by Erno Rubik, a Hungarian designer and architect with a passion for enigma. The first curious fact, however, is that the inventor himself took more than a month to find the solution for its creation. Just think that when the cube was born, Erno didn't even know if there would ever be a solution!
There are several ways, however, to approach the solution of the puzzle. The most intuitive is the layered method: 7 steps to perform and a few algorithms to memorize. The method most used by professional speedcubers, on the other hand, is the Fridrich method, which allows you to solve the cube much faster, grouping second-third, fourth-fifth, sixth-seventh steps of the layered method in single steps.
The Rubik's Cube began to be marketed by Idela Toy Corp in 1980, winning the award for the best game and brain teaser of the year.

The new secret box of our Leonardo Collection is inspired by the famous Medici family, central to the Florence of the Renaissance period.
In fact, on our puzzle appear elegant and refined inlays that could have to do with that historical and artistic period.
Florence, in honor of the Medici, has strewn its streets with the family crest: a shield with red balls on a golden field.
The curiosity lies in the fact that the shields are not exactly equal to each other ... the number of balls, in bisanti heraldry, can vary.
If at first, in fact, the spheres in the coat of arms were equal to eleven, Giovanni di Bicci brought it to nine, his son Cosimo to eight, and the latter's son, Piero il Gottoso, came to reduce it to seven. The last decrease occurred with Lorenzo the Magnificent, who brought the spheres to 6, with the top one loaded with the insignia of the Royals of France.
As to why, then, there are balls in the center of the Medici coat of arms, suppositions
The MOON puzzle is finally available on our site, a new challenge for all fans not only of puzzles but also of space, stars and cosmos.
You too will have a difficult mission to complete on the lunar surface, for which you can draw inspiration from the crew of Apollo 11, in particular the often forgotten astronaut who played, perhaps, the most important role of all.
We are talking about Michael Collins, who passed away last April.
We can start by saying that we also feel Collins a bit of an Italian hero, given his birth in Rome.
In 1963 he was selected as an astronaut and, after being a reserve member of the Gemini VII, he had the great honor of traveling in space twice: aboard the Gemini 10 and, subsequently, the famous Apollo 11.
266 hours in space.
Of Apollo 11, two names are often remembered, Armstrong and Aldrin.
This is because they were the ones who put their faces on it, they were the ones who descended
We don't know the exact moment. The first safe of which we have historical information, however, dates back to Ancient Egypt, precisely to the 13th century BC. And guess what, it was made from wood. Surely arriving at the exact burial place of the Pharaoh was not an easy thing. Pitfalls and traps to overcome without losing body parts or staying dry. For Ramesses II, all this was not enough. He encased his most precious treasures in a wooden safe with a lock similar to that of pin locks. A very ambitious mechanism for three thousand years ago! A further step was taken by the merchants of Ancient Rome, who invented a locking system with fixed flaps to prevent the goods from being stolen. Over time they also began to use flaps of different sizes, so that each safe needed a different key to open. During the Renaissance, a period in which sculpture and architecture flourished like never before, safes became not only more elaborate and safer, but also beautiful to look at. In the
There is a massive text that we will often talk to you about from now on.
It is perhaps the largest written collection ever made in the history of brainteasers and puzzles.
In Puzzles Old and New, in fact, Professor Hoffman, already author of texts on magic tricks and card games, set himself the goal of creating a real illustrated story of all the puzzles to be found, from the past to his present.
After all, we know, starting from the ancient Enigma of the Sphinx, traps and riddles have always fascinated young and old.
Today we want to start from one of the first puzzles present in the pages of the famous text.
It is a thin wooden tray, closed above by a glass plate.
It is called the Planet Puzzle and, in fact, inside it you can see as many small marbles as the planets of the Solar System back then known.
The goal of the puzzle was to get each ball into the hole corresponding to its position with respect to the Sun.
