A Case Study on Extending Rules of Games

Abstract

This study develops a mechanism that allows the flexible addition of new rules to board games and realizes a system that enables the easy creation of rule-extensible games. Previous studies have typically incorporated rules directly into existing game code, but this approach is dependent on game-specific implementations, resulting in a lack of versatility and reusability. This paper describes a method for constructing basic game code using the boardgame.io framework and describing additional rules with a minimum number of lines of code. For evaluation, we measure the number of lines in the rule section and the additional rule section, and determine that sections with fewer lines are easier to expand. As a result, we demonstrate that expansion is possible by changing only the rule logic without modifying the display content or user interface, achieveing high versatility and efficiency. This research facilitates the diverse expansion of board games and the prototyping of new rules, thereby expanding their potential applications.
