Logic Masters Deutschland e.V.

Battle of Actium

(Published on 27. December 2021, 13:30 by Bremster)

This is a puzzle I set and while I was setting it I realised it felt to me like it had a story in the solve which reminded me of what I knew about the Battle of Actium. I then went back and refined the grid to make the solve even more like the battle and incorporate the story elements as much as I could in a sudoku grid.

Rules:

  • Normal sudoku rules apply.
  • Cells separated by a black dot must have a ratio of 1:2. Cells separated by a white dot are consecutive. Not all dots are given.
  • Cells separated by a V must sum to 5. Cells separated by an X must sum to 10. Not all Vs and Xs are given.

Very cool puzzle. Had trouble getting in because I started in the wrong place, but once I found a clean point of entry, the puzzle flowed nicely from there. Thanks for the puzzle!

I really enjoyed this puzzle, but I think it is 1 star, maybe 1.5 at the most. Took just over 9 minutes and probably is more of a GAS+ than a 3-star imo. Either way, really enjoyed it.

BremSter: I would love to know how you did this.
This was tested and solved on camera by some phenomenal solvers and I have had people rate it everywhere from 3 to 5. I understand that difficulty is subjective, but having seen this take 50 minutes for an amazing solver on a stream while getting help... a 9 minute solve is amazingly impressive.

This is a cool puzzle with some neat "ah ha!" moments. It's deceptively difficult just based on the number of clues given, but very satisfying once you've managed to resolve everything :)

Nice puzzle! I had fun discovering the interaction of the clues.
