To congratulate me on getting a high score in the last exam, my mother decided to give me a gift that I love. At that time, I asked my mother to buy me a Rubik's Cube. It's made of hard plastic. It's a three-by-three cube with a length of about 5 cm. Each face of this rubic has nine squares and is painted in one of six different colors, which are white, red, orange, yellow, green and blue. These squares are small cubes about 1.7 cm that are assembled into large blocks and arranged in a messy color and can be moved by rotating according to the joints.The game begins by shuffling all the squares on each side, i.e. alternating colors, then the game ends only when each face of the block is a uniform color. Rubic has a lot of ways to play, it will always know how to make it difficult for players with special cases, thereby helping to exploit the ability to think, solve and increase creativity for players. Everything will be easier when you figure out its sorting rules. When I first bought it, it took me a week to be able to assemble it into a block of the right color, but later thanks to familiarity with my hands, I found some ways to shorten the time.This rubic has helped me relax after hours of hard study. This is a toy that is both fun and helps children increase their reflexes. I will always carry it with me to remind me to always try and not disappoint my parents' wishes.
