Master your mind with this sweet and challenging numbers game. “Sudoku” means “single digit” in Japanese. “Sweet” was a rock band from the 1970s with hits like “Ballroom Blitz” and “Love is Like Oxygen”. Also “sweet” might be an adjective having something to do with candy – it could be why dentists love us. Enjoy driving yourself crazy and sharpening your mind with this Zen and symmetrical puzzle game. It is deceptively simple and insidiously addictive. Sort of like candy itself.
