I've been playing Sudoku for years, and Prime Sudoku offers a pretty good range of difficulties. The 'expert' levels definitely make you think, which is great. I appreciate that it doesn't just hand you the answers too easily. My only minor gripe is that sometimes I wish there was an even 'insane' or 'master' level for those times I really want to pull my hair out! But overall, it's a solid app for keeping your brain sharp.

The interface for Prime Sudoku is really clean and easy on the eyes. I love how simple it is to place numbers and use the note feature – no fumbling around with tiny buttons. The controls are intuitive, whether I'm playing on my phone or tablet. My one suggestion would be to add a few more theme options or custom colors, just to spice things up visually sometimes. But functionally, it's top-notch and super smooth to play.
