One approach to game design is to start with existing ideas and to modify them in interesting new ways. This process of "creative plagiarism" is applied to the Japanese logic puzzle Sudoku to create a new variant called Ludoku, which simplifies some aspects of the original puzzle while adding new strategies without adding undue complexity. This paper describes the design process from initial conception to final product, and how computer analysis was crucial to its success.

计算机辅助拼图设计

游戏设计的一种方法是从现有的想法开始，然后以有趣的新方式修改它们。这种“创造性抄袭”的过程被应用到日本逻辑谜题数独中，创造了一个名为 Ludoku 的新变体，它简化了原始谜题的某些方面，同时增加了新的策略，而不会增加过度的复杂性。本文描述了从最初的概念到最终产品的设计过程，以及计算机分析如何对其成功至关重要。
