14 Sequence Thermometers
(Eingestellt am 25. August 2026, 08:46 Uhr von varepsilon)
Normal Sudoku rules apply: Place the digits 1–9 exactly once in every row, column, and 3×3 box.
Sequence Thermometers: Digits along each thermometer increase in equal steps from bulb to tip, forming a strictly increasing arithmetic sequence.
The 14 thermometers form seven pairs. Within each pair, the thermometers have identical shapes and bulb-to-tip directions—in other words, one can be translated onto the other without rotation or reflection.
The two thermometers in a pair have the same common difference; different pairs have different common differences.
Lösungscode: Digits in row 5, read from left to right.

Took me a second to fully grasp the rules but solved easy and nicely once I got there.

this was one of the most enjoyable puzzles i solved for a while :) Initially I was staring at the puzzle without a clue and was going to skip, but when I realized it I was blown away! it was very smooth after that. The initial idea feels closer to a 2* on my end.

A very nice and easy puzzle. Much easier than it appears.
