Generating Complex Logic Puzzle Maps with WFC

Logic Islands, a puzzle game, features six different rulesets for its maps. Initially, the developer used a traditional backtracking algorithm, but for three rulesets, map generation failed beyond 7x7. To overcome this, the developer cleverly applied the Wave Function Collapse (WFC) algorithm. By redefining tile types and their connection relationships, and setting constraints based on different rules, the developer successfully used WFC to generate large maps (up to 12x12) that satisfy various rules, solving the previous map generation problem. This case demonstrates the power of the WFC algorithm in generating complex logic puzzle maps and the importance of thinking about problems from different angles.
