how to verify that a puzzle is solvable?

[Dee]

How can I verify a puzzle that I have entered from a newspaper is solvable with SudoCue? What menu item, etc. do I select?

Once the puzzle is solved, how can I tell that it is solved correctly? Again, what menu item, etc. would I select.

I am new to this software and appreciate any help I can get .

Thanks,
Dee

Hi Dee, welcome to the forum.

After you have entered the data for the puzzle select menu option File..Play.

There will be 3 small numbers at the bottom right hand corner of the window and the word Easy, Moderate, Tough, Hard or Unfair. Most newspaper puzzles will be either Easy or Moderate, even ones they might rate as being hard. Ruud needs extra levels as some of his puzzles can get VERY tough.

If you see the word Invalid then either the puzzle is not solvable or has multiple solutions or more likely you've made a typing error.

If you want to see the solution select Solver .. Solve.

Lastly if you are online then F1 will get you to the Sudocue help page, where you can find out about all the other wondrous things Sudocue can do.

Hope this helps, have fun.

Glyn,

Thank you for your answer to my question... very helpful, indeed .

Do you know if there is a way a person can save a puzzle on which they are working and retain the 'pencil marks'?

Thanks again for your assistance,

Dee

if you have it in sudocue file/save as.

Give it a name you can find "PragueGazeette2aug07easy"

that saves all the marks the puzzle and you can backup ^Z to the origional posistion, if you load it again..
