Normal sudoku rules apply.
Place the digits 1-8 in every row, column, and 8 cell region. Clues give all sums of continuous cells separated by region borders or the edge of the grid, in order from highest to lowest. ? means the sum is lower than 10 and ?? means the sum is at least 10.
For every possible two-by-two region that does not contain a shaded cell, there may be a maximum of two even digits (2, 4, 6, 8), and a maximum of two prime digits (2, 3, 5, 7).

I like this puzzle.
But why from right to left and from bottom to top in the solution code?
This is because some people complain about having to type out 18 digits instead of 9 and the normal codes for years were 18 digits so I want to mess with people's heads a bit when they start to complain. - Isaiah
