Uni Sudoku for Mac

After upgrading to V.3.0 via the App Store, UniSudoku would not display any games. I could not open or create any games. It just sat there. I went into the time machine and brought back V.2.0 which has worked perfectly. (Mac OS X 10.6.8 2.33 GHz Intel Core 2 Duo 4 GB 667 MHz DDR2 SDRAM) P.S.: I sent an email to the developer regarding this problem.

After trying several Sudoku games, I happily purchased UniSudoku. Why? 1) The auto-generated puzzles are true Sudoku puzzles. I tried others that were too easy & could be solved by chance rather than logic. 2) The user interface makes it easy to enter numbers and pencil marks - just click in the box. Its the most playable Sudoku I tried by far. It's a bit plain but I prefer that to the garish style of some others. It's the closest I've found to pencil & paper with the advantages of the computer. 3) The highlight numbers feature helps solve hard puzzles. There are some programs with more "solver" capabilities, but this is the one I enjoy playing. I'd suggest reading the user manuel for "Sudoku Susser" to learn advanced Sudoku strategies, but for playing Sudoku - I use UniSudoku.

My favorite implementation of sudoku but why does it hog 98% of my cpu right after I start a new puzzle?

Sweet looking software. This makes playing Sudoku much easier then on paper

lumineux, how is this better than any other sudoku program?
