Sudoku. How do you score 100K+?

When I play Sudoku, I never score more than 10K, 20K, 30K or 40K depending upon the level I play.  But I see high scores in excess of 100K?  How do I score more than the basic max score for each level?

Thanks for your question, @Kat903213V! Sudoku scoring includes two bonus multipliers that vary by level, one for difficulty and one for time. Final score is calculated with the percentage of puzzle completed without errors (or help) multiplied by difficulty bonus + time bonus.

 

Difficulty bonus is:

  • Easy = 100;
  • Medium = 200;
  • Hard = 300;
  • Expert = 400

 

Time bonus is your time spent solving subtracted from:

  • Easy = 180 seconds;
  • Medium = 360 seconds;
  • Hard = 540 seconds;
  • Expert = 720 seconds

 

If your time spent is more than the time bonus amount, the time bonus does not apply (i.e., you are not penalized with a negative number as a multiplier).

The scoring formula should be written as  percentage completed without errors * (difficulty level + remaining score) which yields a maximum score of 112,000 if you could somehow complete the puzzle in 0 seconds.  I have gotten in the mid 80,000s but that seems to be my limit.  To get 100,000 exactly, you would have to complete the expert puzzle in 2 minutes.  That would give a time bonus of 600 (720-120)  so you would get 100*(400+600) which is 100,000.  It is possible to "cheat" at Daily Sudoku by completing the puzzle correctly in Chrome's Incognito mode without logging into the AARP website, then making note of all of the numbers.  You can then exit out of Chrome, come back in, log into AARP and then redo the same puzzle and quickly re-enter all the correct numbers.  To me, that is cheating but I'm sure some people do it.  The normal Sudoku puzzle gives you a new puzzle every time so this cheating method won't work for that.

Why is completion time even scored.  Correct answer should be the deciding factor.  Why does America always want to add a stress factor?

I wonder the same thing. I play the expert level, complete the puzzle at 100% with no errors and it's always 40K. I don't understand how to score more than that.
