Simply Sudoku by CG

Clean, elegant Sudoku. No ads, no in-app purchases, no locked features — just pure puzzle joy.

Every puzzle is freshly generated with a guaranteed unique solution. Choose from five difficulty levels — Easy, Medium, Hard, Expert, and Master — each requiring progressively advanced techniques to solve.

LEARN AS YOU PLAY A built-in coach teaches you 20 real solving techniques, from Naked Singles to X-Wings to Forcing Chains. When you get stuck, the coach highlights exactly where to look and walks you through the logic step by step. You don't just get the answer — you learn how to find it yourself.

DESIGNED FOR FOCUS Customizable layout with two number pad styles, portrait and landscape support, and drag-and-drop input. Smart candidates fill in possibilities automatically. Undo and redo let you experiment freely. Everything you need is a tap away, and nothing you don't.

MAKE IT YOURS Six color themes — Classic, Ocean, Sunset, Lavender, Rose, and Midnight — with full light and dark mode support. Save and load games. Share a completion card with your time and stats when you finish a puzzle.
