Enough levels to challenge anyone. It’s how I start myday ### 5/5 — The most challenging entries ever *2019-12-17, version 1.1* This sudoku app has the most challenging entries at the 'Expert' level. Solvable, but I had to use the Hint at least once to complete some entries One minor problem -- the screen is to small, can hardly see the note numbers. Other than that---I love this app. ### 3/5 — Good game, needs a better layout *2018-03-15, version 1.1* Notes should be moved and some supposedly easier games are harder than genius. ### 5/5 — Great game *2017-07-15, version 1.1* Lots of variety and different levels of difficulty ### 5/5 — Yep does what it says *2017-07-05, version 1.1* I like it. ### 3/5 — A lot to like, but problems too *2017-01-12, version 1.0* I'll start by saying I like this game overall but there are some things that are very irritating. The play is good, the notation system is good, the features are good, but the main problem is in the difficulty of the levels. For instance, in many cases, games at the skilled level are more difficult then games at the genius level. There is no real consistency. My other problem is with the colors of the interface. The background color -- I guess it can be described as Dijon mustard -- is a color I hate, and it can't be changed. There are 16 color combinations for the board, but only maybe 2 are usable. (They hearken back to the horrifying color schemes of Windows 95.) Also, in terms of color, I'd love it if the notes were a different color than the played numbers. They'd be much easier to read at a glance if they were, for instance, aqua, or anything but yellow. ### 3/5 — Tougher puzzles; layout poor *2016-01-26, version 1.0* If I could I would give 5 stars because the puzzles are more difficult; but 2-3 stars for poor layout. Puzzle NEEDS to be larger and the "Note" button near the number keys. Should be an easy update?? How about it Mighty Good Games? ### 2/5 — Good game, bad layout *2013-12-03, version 1.0* The game play is as good as that on the iPhone version but the game is marred by the poor use of space. First, there is plenty of room to make the board bigger, to save eyes and give better targets to chubby fingers. Next, the Note button should be situated near the number pad, so that notes can be more quickly toggled. This feels like a quick and dirty re-arrangement of iPhone app elements to wherever they fit, rather than a layout devised for the bigger screen. ## Frequently asked questions about Expert Sudoku HD ### What makes Expert Sudoku HD different from other Sudoku apps?
