About SudokuPulse - Meet James Hoss
Meet James Hoss — The Mind Behind SudokuPulse
SudokuPulse was founded by James Hoss, a competitive Sudoku solver and puzzle designer with over a decade of experience in logic puzzles. James has competed in national-level Sudoku championships and has spent years studying the mathematical structures that make Sudoku puzzles both challenging and solvable.
“I built SudokuPulse because I wanted a place where anyone—from complete beginners to advanced solvers—can find well-crafted puzzles and genuinely learn how to get better. Every technique guide on this site comes from real solving experience, not just theory.” — James Hoss, Founder & Sudoku Expert
Background & Expertise
James discovered Sudoku while studying mathematics in college and quickly became obsessed with the logic and patterns underlying every puzzle. What started as a hobby evolved into competitive solving, and eventually into designing puzzles and teaching solving techniques.
His areas of expertise include:
- Advanced solving techniques — from naked singles to X-Wings, Swordfish, and XY-Wings
- Puzzle grading and difficulty analysis — understanding what makes a puzzle easy, medium, hard, expert, or evil
- Teaching and educational content — breaking down complex strategies into step-by-step guides that anyone can follow
Every technique guide, strategy article, and puzzle on SudokuPulse is reviewed by James to ensure accuracy and clarity.

- Clarity for all levels — Guides are written so that a beginner can follow along, while still providing depth for experienced solvers.
