In the video, a person is playing a game where they are building a wall with purple blocks. The person is using a tool to place the blocks on top of each other, creating a pattern. The wall is made up of several rows of blocks, and the person is adding more blocks to it. The game appears to be a simulation or building game, where the player can create structures and designs using different types of blocks. The purple blocks are a specific type of block in the game, and they are used to create a particular design or pattern. The person is focused on their task, carefully placing each block to ensure that the wall is even and well-constructed. The game environment is not visible, but the player seems to be in a virtual space where they can build and create structures.
