A game machine provides play of a game wherein a hit is made or lost and including: character storage for storing information about a character which is provided separately from the game; and character raising for growing the character, which has been stored in the character storage, when the result of the game is a predetermined hit. The device is plugged into an electrical outlet using a set of prongs like those used in the electrical plugs of typical household appliances. In other embodiment, the Schottky contact may not be formed within a recess, and a doped region may be formed within the semiconductor layer under the horizontally-oriented lightly doped region and have a conductivity type opposite the horizontally-oriented lightly doped region.
