A person is playing a block-puzzle game on a smartphone. The screen shows a playing field with a partially filled grid and two blocks available to place: a green square and a blue L-shaped block. The person touches the screen to drag and drop the blue block into the grid next to the yellow block. They then use the green block to add it to the bottom row. The game scores increase as they place blocks. The phone is being held in the hand, and the background is blurry.
