The invention provides a device and method for making fancy ice. The device comprises an ice making box and evaporation pipes. The ice making box comprises an ice making inner cavity. The evaporation pipes are located at the bottom of the ice making box and used for cooling water in the ice making inner cavity into ice. The device further comprises a diversion structure arranged on the ice making box and used for leading water exceeding the maximum water capacity of the ice making inner cavity out of the ice making box. According to the device for making the fancy ice, when a small amount of water is supplied into the ice making box and kept still, the small amount of water can be completely cooled into white ice through the evaporation pipes; when water continues to be supplied to the surface of the white ice and flows on the surface of the white ice, the diversion structure can lead the water exceeding the maximum water capacity of the ice making inner cavity out of the ice making box, the evaporation pipes cool the water on the surface of the white ice into a layer of transparent ice, and therefore the white ice and the fancy ice with the transparent ice layer arrayed in an overlapped manner can be made.
