Yes, Minfang Lin mentioned that in most puzzles the carry-forward digits are determined at the end. But not in all cases.
As much as we want to be lenient, and mark P04 as correct for you, but I think it will be unfair to several who have some initial puzzles submitted wrongly. Once the detailed results are up (in 5 minutes), check Semax, don3232, sinchai4547.

It has been long pending thing, but I think the best solution is to add "Auto-Submit" for Sudoku tests. Unlike puzzles tests, each Sudoku has its own Submit button. And it is easy to forget to click on "Submit" in the heat of time. We see that after every test some players forget to submit some sudokus.

Once all required cells are filled, the sudoku should be auto submitted

Congratulations to Jun Yan, Ce Jin, Jakub Ondrousek for topping in X-mas Special Sudoku Test.
146 ( of 166 ) players got non-zero scores.

Thanks to everyone for taking time out during Christmas to participate in the test.

Thanks to team TTLC for the wonderful set of Classic Sudokus. It was only fitting that there were many players from China (some playing from sudokufans.org) and 2 players from China occupied the top spots.

Indian Results - Rishi continued his brilliant performance over last few months, and finished all sudokus just in time.
Sumit and Gaurav, both after a long hibernation, finished 9 puzzles each, but still ahead of others.

Nice to have you back guys! Hope you guys participate more.

LMI Mumbai meet -

utkaarsh, Mahesh Iyer, Hiral Parikh, Ishita Meshram, prasanna16391, amitsowani and gauravkorde

Details about the meet will be updated in the other thread.

one suggestion regarding the submit button. why not have only one button "submit all" at the bottom instead of having individual buttons for each puzzles.

if someone wants to try the original puzzles download this file

ps: the first 8 puzzles can be solved by single.

Thanks for the suggestion. We'll do either this OR auto-submit for the next Sudoku test.

So, my mistake was that I wrongly copied out a digit from puzzle 8 to puzzle 9, making it really difficult to solve. So difficult that I had to guess - but solved it anyway (in fact, with this wrong digit, it had several solutions). Checked the solution (obviously my guess had encountered no contradiction), then transfered digits into puzzle 10... and only there I realized something was wrong, as I couldn't transfer them properly.

Never mind !

That is one of the dangerous problems with relays. You make one mistake, but you might realize it only much later.
