Sometimes different constraints are identical, at least under some conditions. For example, these are all two-cell thermometers, which could be replaced by greater-than or lesser-than symbols. So I don’t create puzzles with greater-than or less-than symbols. I use two-cell thermometers instead!
Rules:
Normal Sudoku rules apply.
Digits on thermometers strictly increase from bulb to tip.
Estimated difficulty: 2 out of 5
