Pretty good game! Easy to use -- EXCEPT----

Pros
Cons
I wish it would "save" my option picks! I have to change the defalt setting each time I open it. I like to pick the cell BEFORE the number so as not to lose track of where I want it! Also, I have to use the keyboard for the number pick cause I don't like the bottom line, small button arrangement.
Summary
Relatively useless.

Pros
-- Numbers can be erased with a single click. -- There are undo and redo buttons.
Cons
-- Puzzles do NOT have unique solutions. Every single puzzle generated had multiple solutions. There is a solve button, that will show a solution. But that solution is just one of several. -- I could NEVER get the Hint button to do anything. -- Placing numbers in cells requires clicking on numbers and then cells, or vice versa. This is the case with most free programs, but there are some good ones that only require clicking once on a spot within the cell. -- NO ability to write multiple numbers in a single cell. -- NO help file. -- NO way to check your progress. -- NO way to determine what to do next, if you get stuck in a puzzle. -- There are a number of free internet Sudoku, that are marginally better.
