Experimental Puzzle 4/6: Thermo
(Published on 18. May 2026, 20:40 by Sudokujoker)
This is the fourth puzzle in a short series of experimental puzzles. The first five puzzles in the series each explore one constraint in a 6x6 puzzle, and the sixth puzzle combines all five constraints in a full-size sudoku.
Normal 6x6 sudoku rules apply: place the digits 1-6 in each row, column and 2x3 box. Dynamic fog: the grid is covered in fog. Correctly entering a digit will clear the fog in that cell and may clear the fog in other cells too. Thermo: along a grey thermometer digits must increase starting from the bulb.

I don't think it does... keeping track of the options for each cell is easy in a 6x6, and that's all you need (well and knowing that some digits cannot go in all spots on a thermo, but that's obvious isn't it)

the rules need to state that thermos don't branch or cross
