ThermoBan Chain
(Published on 28. February 2026, 14:30 by Cassinii)
Rules:
1. Normal sudoku rules apply
2. Thermometer: Digits on a grey thermometer strictly increase starting from the bulb end.
3. Renban: Digits on a purple line form a non-repeating, consecutive set in any order.
4. Killer Cage: Digits in a cage sum to the total given in the top left of their cage.
5. Kropki Dot: If 2 digits are either side of a black dot, one is double the other.
6. Odd Circle: A digit in a grey circle is odd (Not to be confused with thermometer bulbs, which can be odd or even).
Have fun solving :D
Solution code: Row 4, left to right
