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.

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

Disturbance gone and answers submitted, I had just enough time to finish the 9th puzzle... but did a very stupid mistake which I couldn't fix. I will explain why tomorrow (well, today, for indian readers), when the test is over.

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.
