6x6 Chaos Construction (Odd Even Coded X-Sums)

(Published on 1. May 2022, 02:31 by cfop)

Normal irregular sudoku rules apply
Fill each row, column and region with digits 1-6 once each. The regions however are to be discovered by the solver.
X-Sums: A clue outside the grid indicates the sum of the first X cells in the assigned row or column where X is the first cell. Furthermore these first X cells belong to the same region whereas the next cell belongs to a different region. A question mark can signify any positive integer.
Clues, however, have been encrypted. O for odd, E for even. (In case of two letters: first letter = tens digit, second letter = units digit). Two letter clues do not start with zero.

Got hit by a huge difficulty spike at one point but after that it went smoothly again, pretty fun puzzle nonetheless :)
