I made this puzzle following Scojo's prompt to use tentropy lines on an anti queen puzzle.

  • Pick seven digits out of the set 0-9 and fill the grid with them, one per cell.
  • Cells that are a chess queen's move apart may not contain the same digit.
  • Every set of 4 adjacent values along the tentropy line must contain one value from each of the sets 19, 28, 37, 46.
  • Digits joined by a black dot are in a 1:2 ratio.

Very nice puzzle! Caught the trick right from the beginning, and then my brain started to complicated things by itself xD
Thanks Scojo!

I liked the puzzle... colouring took me a while though so I'd say it's somewhat harder than a 2*.

Struggled a bit at the start because I interpreted "one chess queens move" wrongfully (thought it meant 1 cell in a chess queens move). "a chess queens move" would be more explicit wording.

Afterwards really smooth and fun puzzle.

good idea, thanks!
