One Hot Black Knight
(Published on 5. June 2026, 00:08 by AaronH)
Rules
Normal sudoku rules apply: fill the grid with digits 1-9 so that no digit repeats in any row, column, or 3×3 box.
All variant clues follow their standard meanings; full descriptions are provided below.
- Anti‑Knight: Cells a knight’s move apart (as in chess) may not contain the same digit. The Anti-knight icon is a reminder for this rule and has no special meaning for the cell it is located in.
- Black Kropki Dots: A black dot indicates one digit is exactly double the other.
- Killer Cages: Digits in a cage must sum to the number shown in the corner.
- Thermometer: Along a grey thermometer, digits must increase when moving from the bulb to the tip.

Added anti-knight icon to puzzle as a reminder for the rule

This is a very nice puzzle, and much much easier than most on this site. If you're new to the variants here -- black kropki, killer cages, anti-knight -- I recommend this puzzle as a good example of the patterns that arise from them.
