A method of manufacturing a packaged semiconductor device includes mounting a semiconductor device having multiple leads. Indicia indicating numbers from 1 through 60 are arranged on the game surface in ascending order with half of the numbers associated with a first color and half associated with a second color. The parent game device detects a degree of progress of a game of each child game device, selects for each child game device predetermined display information data out of a plurality of display information data on the basis of the detected degree of progress of the game, and creates different parent game device data for each child device on the basis of the display information data. An exemplary embodiment of a driver circuit can implement a comparator andor a voltage regulator to allow for improved output current uniformity for high-voltage applications and loads, such as series configurations of LEDs.
