James Sinclair shares his remarkable journey from immigration lawyer to full-time puzzle crafter and creator of the Artisanal Sudoku Substack—a haven for lovers of elegant, human-made Sudoku variants.
In this episode, James breaks down his puzzle design philosophy, his preference for handcrafted logic over AI generation, and how he’s turned personal passion into a growing newsletter, a community of solvers, and a published puzzle book. The conversation covers everything from the joys and challenges of variant Sudoku to the deeper question: What makes a puzzle satisfying to solve?
James also shares thoughts on monetization, platform choice, audience building, and why central hubs like Logic Masters Germany play a key role in the global puzzle scene. Plus, he previews Sudoku Con, talks about the fog-based puzzle design he’s experimenting with, and gives rapid-fire takes on puzzle pet peeves, dream collaborations, and favorite solves.
