Very clear layout now (we must wait for the 3 or 4 cell cages ... ), btw, the nr. 3 is a little bit more difficult than the previous 1 and 2, but not too difficult. Are you using the same algorithm to obtain the "solving rate" for these "addition" sudokus?.
Yes, the same algorithm.
But the solver is missing a key tool for these puzzles: using the "45 rule", both
for rows, columns, and the 3x3 boxes (!)
So puzzles are often overrated.
