Day 14: The third sunday of advent
(Published on 14. December 2025, 06:00 by SharpFox)
Today, three candles are already light. Time to inorporate this into the Sudoku as well.
Rules:
- Normal 4×4 Sudoku rules apply.
- Three candles are lit and spread their light in a circle. A digit N in a circle indicates, that the digit N appears exactly N times in circles.
- Each candle also has different temperatures and acts as a thermometer. Digits strictly increase along a candle, starting from the flame.
- The christmas tree represents the number of layers of branches it shows (4).
Solution code: Row 4 (4 digits):

The image of the Christmas tree on this site shows the correct number of layers of branches. The one for me on SudokuPad has 5 layers, so I was confused by that rule at first. The solve was nice after double checking the picture of the tree here.

I didn’t understand what you meant by “Each candle also has different temperatures and acts as a thermometer.” I assumed that “different temperatures” meant they were all unique, but they weren’t. Nice snack though.

Hallo DK_48, das mit den verschiedenen Temperaturen war bloß eine Art Erklärung, warum die Kerzen auch als Thermometer funktionieren.

Für mich ist es widersprüchlich, dass „Jede Kerze hat verschiedene Temperaturen“, aber bei der richtigen Lösung zwei Kerzen die selben beiden Ziffern besitzen?!
