An hourglass is a sealed flask, narrowed in the middle, containing sand inside. When turned over, it is poured into the lower part of the flask for a certain fixed time. In the game Vials: ASMR Sand Sort Puzzle, you must distribute colored sand into flasks so that each contains sand of the same color. Click on the selected flask and then on the one where you want to pour the contents, you can only connect sand of the same color in Vials: ASMR Sand Sort Puzzle.
