A light-emitting magic cube is provided to express a desired color through radiating elements and to maintain intelligence-improving or mental simulation functions after being used for a long time. A light-emitting magic cube includes a central body(11) and plural cubic blocks(12). The central body includes a power unit. The plural cubic blocks are arranged on the main edge of the central body to form a magic cube that has or shares nine cubic blocks on each surface to be able to rotate. Each cubic block has at least one radiating element(15) that is arranged at the inside thereof. The single radiating element of the central cubic block of each surface is electrically connected to the power unit of the central body. Parallel circuit units connecting the radiating elements of cubic blocks are formed around the central cubic blocks.
