In the video, a person is playing a game where they are building a structure using various blocks. The person is seen placing blue and white blocks on the ground to create a pattern. The blue blocks are square-shaped and have a shiny surface, while the white blocks are rectangular and have a matte finish. The person is using a cursor to place the blocks in a specific order to create a design. The game appears to be set in a virtual world with a clear sky in the background.
