Standard Sudoku rules apply. Numbers outside the grid indicate the sums of digits in groups of shaded cells in the respective rows/columns in order of appearance (a dash (-) means 'up to and including'). Question marks (?) indicate any digit from 0-9 with for instance ??? being a 3-digit number. However, all clues given are a positive integer. There is at least one unshaded cell between groups in a row/column. In addition, unshaded regions, that consist of orthogonally connected unshaded cells, contain at least 5 cells.

link seems to no longer work.

Clarification: is it possible for the first "?" of a "??" be zero (basically, can "??" be a single digit number)?

It is a very good puzzle with a logical solve. It gives you just enough information and it's not brutally hard. It is very challenging but was a very enjoyable and satisfying solve. The puzzle holds up and does not fall apart to the very end. There is also an "Easter Egg" after you solve the puzzle for those of you who enjoy watching others solve puzzles like this on YouTube.
