Normal Sudoku rules apply.

Digits along a thermometer must increase from the bulb. Numbers outside the grid indicate the sum of the digits along their marked diagonal (digits may repeat.) Digits connected by a V or X must sum to 5 and 10 respectively. (Not all XV pairs are indicated.)

The perimeter cells of the grid sum to 172.

1s and 2s may not appear orthogonally adjacent to each other.
