Pour the chilled citrus Gatorade into the blender.
Add the ice cubes to the blender with the Gatorade.
Secure the lid on the blender and blend on high speed for about 30-45 seconds, until the mixture is thick and slushy with a frosty texture.
Pause briefly and check the consistency; if needed, blend for a few more seconds to ensure the ice is evenly crushed and the texture is smooth.
Pour the vibrant, icy slush into chilled glasses or cups.
Serve immediately with a straw or spoon for a cool, tangy refreshment.
