Nod to Sumanta Mukherjee
This puzzle blatantly steals Sumanta Mukherjee’s ideas behind Code 62: Hi Five. I watched Simon's solve and thought the concept was brilliant, so I wanted to see if I could come up with something along those lines. Hopefully, I have introduced enough to change things sufficiently. If you solved that puzzle, or watched Simon’s solve, then you will have a good head start on this one.
This is meant as a learning experience for me, and is not intended to be something new or original.
Standard sudoku rules apply.
Digits along a thermometer must increase from the bulb end to the tip.
A clue outside the grid gives the sum of the digits along the indicated diagonal.
Digits connected by an X must sum to 10, not all Xs are given.
