The easy ones aren't all that easy, however. When I play a game, I don't want to think all that much sometimes so play another version. I do really like this, though. ### 4/5 — Fun *2015-01-25* Annoying that they asked me to review every time I opened the app ### 3/5 — Yup *2015-01-19* Yup ### 5/5 — Fun and addicting *2015-01-08, version 1.0* When I open the game and start playing, I'm addicted. It's such a simple concept, but yet, you have to have lots of strategy. Really super fun game that makes you use your brain a lot. ### 2/5 — Only works in landscape *2015-01-04* Only works in landscape ### 5/5 — Close to the real thing *2015-01-03* The draw back to most iPhone game is the lack of a place for notes. This game lets you ID patterns and note options. It lets me play the way I do on paper ## Frequently asked questions about :-) Sudoku ### What are the difficulty levels in :-) Sudoku? :-) Sudoku offers three distinct difficulty levels: easy, medium, and hard.
