GUCCI
GUCCI writes the articles and strategy notes on iLoveSudoku, and operates the site at ilovesudoku.app.
The puzzles, the combination table, and the technique pages are the work. Each board keeps a permanent number. Difficulty is the hardest logical step the puzzle needs, and two solvers have to agree there is one solution before that number is assigned.
Write to support@ilovesudoku.app with a correction, a broken hint, or a puzzle that does not behave.
Read the articles, the strategies, or the note on how the site is run.
