Mystery Sandwiches or X-Sums

(Published on 18. November 2020, 01:59 by UnnamedSorcerer)

Normal Sudoku rules apply. Fill in each row, column, and region with 1 through 9. Digits must increase from the bulb end along thermometers. Clues outside the grid indicate either sandwiches or X-Sums. If there are two clues in a given row or column, and if one clue is a sandwich, then the other must be an X-Sum, and vice versa.

X-Sums: the sum of the first X cells in the row/column from that direction, where X is the first digit in the row/column.

Sandwiches: Clues outside the grid show the sum of the digits between the Y and the Z in that row/column, where Y and Z are consistent for the whole puzzle.

Inspiration to combine sandwiches and X-Sums comes from this puzzle by shye.
