Knight Prime Killer
(Published on 11. October 2020, 10:29 by Jon Allan)
- Normal Sudoku rules apply - fill each row, column and box with the digits 1 to 9.
- Any connected red, blue, or yellow region is a cage which must sum to a prime number. These sums may differ between cages.
- A chess knight on any digit may not threaten the same digit.
- Digits on thermometers increase from their bulbs.

...better wording, should hopefully be clear now.

@SKORP17 - I've clarified the rule. Each cage adds to a prime, the colours are just different to separate the regions. So, "pro farblichem Käfig" (My German is non-existant, sorry).

@SKORP17 Every individual cage adds to a prime number, that was my best guess anyway.

Regeln unklar, Primzahl pro farblichem Käfig, oder insgesamt pro Farbe ?
