Pi sudoku solved.
1234+567+89 solved too. Not very cleanly

, but perhaps I didn't thought enough about logic of these puzzles
(like: when the last digit of a sum is 5, sum of the 3 units is 15
(5 or 25 isn't possible
),...
)
I didn't like calcdoku, but I think I'm in progress

.
Quite often the 1000's place column of 1234 gets solved immediately.
