If a cell is a clue, then 100 is added to the cell.

Thanks. That was an opportunity to exercise some ancient code of mine. Please note that the very last puzzle is invalid. For instance, the last row contains 9 and 109, and 5 and 105, but neither 1 nor 22.

Sorry, some problems are wrong.
Please wait for these problems to be corrected.

[Naoki]

All problems have been corrected.

[m_b_metcalf]

All problems have been corrected.

Thanks. They are very pretty. A question remains: in the one below should r10c25 be 102 rather than 2?

[Naoki]

Thanks. The number '2' in r10c25 has been replaced to '102'.

[gsf]

All problems have been corrected.

Thanks. They are very pretty. A question remains: in the one below should r10c25 be 102 rather than 2?
