How the Ultra Sudoku Solver Software Works:
Run Ultra Sudoku Solver and key in the starting Sudoku numbers, or click one button and create your own Sudoku instantly from a choice of six difficulty levels, then you begin the solving experience.  Use the optional Show Possibles feature to continually display the remaining cell possible values (candidates) as you solve the puzzle.  As you apply your analyses, edit the digits in the right grid eliminating cell candidates and reducing the possibilities.  As you enter solution digits in the left cells, the possible values of the remaining cells are automatically updated on the right.  While you edit the possible values in the right cells, you are narrowing the remaining candidates of the puzzle ultimately reaching a complete solution.

Ultra Sudoku Solver makes solving Sudoku fun!  No need for paper, pencils, erasers, scratch paper, or tedious creation of a possible candidates list for each puzzle cell.  The software prevents your errors by optionally creating the "Possible Values" list for unsolved puzzle cells for you, and at the same time keeping the list up-to-date as you progress toward the solution.  Errors in the current possible cell values are one of the biggest factors preventing Sudoku solvers from completing puzzles successfully.  This won't happen to you.

You may click on the Print Puzzle button anytime and your partially solved puzzle with the remaining possible values for unsolved cells are printed freeing you from being tied to your computer.

Toggle-on the optional Auto-Fill feature which automatically detects only one possible remaining value in unresolved puzzle cells and Ultra Sudoku Solver auto-fills those cells for you the moment you enter any solution digit anywhere in the puzzle.

Help When You Get Stuck:
Have you become stuck solving a puzzle?  Well, not any more!  Use the convenient Save button that saves the puzzle, as it then stands, to your hard drive.  The Restore button reloads the stored puzzle from the hard drive so you can: 1) recover from errors you may make, or 2) come back later to resume an interrupted puzzle.  A Delete button deletes the stored puzzle when you no longer need it.

Don't know how to proceed?  There's a 1 Step button waiting for you.  Click it and the software advances one step from wherever you are in solving the puzzle giving you an explanation of what it accomplishes in that one step.  Perhaps, after using 1 Step just once, you can continue on your own.  It's like a hint, only better.  The 1 Step feature may be used as often as you want.

Are you really stuck?  Then click the Solve It button and the software will solve your puzzle for you.  Then a click of the Details button displays the step-by-step processes the software used to solve your puzzle right down to the action taken at the cell level ... or click the Summary button for a recap of the rules used to reach the solution.

There's a built in complete Help feature.  Click the Help button and select from the 23 help categories.  Or click the Rule Explanations button and select from the 54 puzzle solving rules for a full English description of each rule, how to recognize its presence in a puzzle (with on-screen examples), and what do when you find the rule-satisfying conditions.  There is even a step-by-step beginning-to-end example of solving a fiendish-rated puzzle.
