I got a Rubik's Cube in Grade 6, and I know this is very late to be blogging about it, but I am doing it anyways. I couldn't think of any other topic, so I'll be commenting on the puzzle mankind has struggled on for about a year.
The Rubik's Cube is a toy puzzle composed of 26 cubes of different colours, put together so that they form a 3x3x3 cube. A completed Rubik's Cube has 6 sides of one colour. Once you scramble the Cube, it is practically impossible to solve it without knowing the proper formulas. Once you learn and remember these algorithms, and with a little bit of practice, it's easy to complete the Cube and dazzle your friends.
Right when bought, some Rubik's Cubes are tough and hard to turn, so I took apart my Cube and moistened the inside of the Cube with lubricant. Now, it spins quickly and smoothly.
There are different algorithms that are useable, and the more complicated ones are much harder to learn, but if you use them properly, they are very efficient. One of these advanced algorithms is F2L (First 2 Layers), which completes the first two layers of the Cube, leaving only one last layer to be completed. It is a very common shortcut, and it takes some time to learn.
Using this and other advanced algorithms, the greatest Rubik's Cube solvers in the world can complete a Rubik's Cube in under 10 seconds. My personl best is 45 seconds, and this includes a lucky break. This lucky break is when you complete the first two layers, and the final layer is already completed. This happens when the scrambled version of the Cube is in a specific format so that the final layer can be completed just by solving the first two layers. It is very rare, and I have only been lucky 4 times so far since I had the Rubik's Cube.
There are many variations to the Rubik's Cube, such as the 4x4x4, or the Pentamix, and they are even harder than the 3x3x3. Anyone who can complete the Pentamix under 5 minutes is a genius.
This was my blog about the Rubik's Cube.

do you dare to try the Pentamix?
ReplyDeleteno way, it's too hard
