The name says it all, and it delivers on the promise. In an era where mobile games are increasingly cluttered with microtransactions and pop-up videos, Sudoku No Ads is a breath of fresh air. It’s a pure, unadulterated logic experience.
The board is crisp, and the 'pencil marking' feature is implemented better here than in almost any other version I've played. It also features a great smart-highlighting system that helps you spot conflicts without being so obvious that it ruins the challenge. It’s the definitive Sudoku app for the minimalist gamer.
