Thread - LMI December 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.

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