Over time, the game didn't let you know of errors so I would keep playing only to find out that the numbers were totally incorrect and there was no way to backtrack to where the 1st incorrect number was entered. ### 5/5 — Great game *2014-06-19, version 1.0* Thus game is the bomb ### 5/5 — Great game *2013-11-03, version 1.0* I love playing this game. I have to watch how long I play because it is really easy to go on for hours. I highly recommend this app! ### 5/5 — Sudoku *2013-09-22, version 1.0* Mind Challenging, and Fun! Love the graphics😄 ### 5/5 — Sudoku *2013-06-10, version 1.0* Game difficult, but once you learn & study it becomes a very exciting challenge game. I love it! ### 2/5 — Great UI *2013-06-08, version 1.0* First of all, the format and UI of this game is the best we've seen. I love it! Unfortunately, the puzzles themselves are not valid puzzles as there is more than one solution far too frequently. Fix this and I would not only pay for the app, but I would encourage others to do the same. ### 5/5 — Mr k k *2013-06-01* Such a good brain exercise and very good fun as well. ### 3/5 — Fun but hard to see *2013-04-13, version 1.0* Like the previous review mentioned, the notations don't show up very clearly on the dark tiles. Needs higher contrast or option to change either background colors or font colors. That aside, it is a great game and otherwise very nice looking. ### 3/5 — Sudoku *2013-04-07, version 1.0* Love the app but can't read notations on dark tiles ## Frequently asked questions about Sudoku Exercise ### What is Sudoku Exercise?
