The user or installer of the dart game apparatus may set whether to drive the dart game in various ways. In particular, when the function unit 100 necessary for driving the dart game does not operate, the dart game device may be set to be impossible to drive the game. For example, since the dart board 150 is necessary for driving the dart game, it may be set that the game driving is impossible when the dart board 150 is not valid. In addition, when the dart game is provided by the business, payment of the game fee is necessary, and thus, when the bill / coin recognizer 110 and the RFID reader 120 are not valid, the game may not be driven. In the case of providing a dart game at home, it is not necessary to settle the game fee, so that the game can be driven even when the banknote / coin recognizer 110 and the RFID reader 120 are not valid.

In the game driving mode field 42, the identification value of the driving mode is recorded so that the game driving mode can be identified based on the combination of the valid functional units 100 recorded in the validity field 44 of the functional unit. The driving mode may be divided into, for example, a business mode when a dart game is provided at a business place and a home mode when a dart game is provided at home. Meanwhile, a game program corresponding to each game driving mode may be stored in a separate DB (not shown), and the game driving module 330 may drive a dart game by calling a program corresponding to each game driving mode. .
