SCS #2: JSudoku generated + a single Clue by me.

Post by Børge »

Substitute Clueless Special #2

Again I started with a puzzle generated by JSudoku and once more just added a single clue to "tame" it, i.e. to get rid of many advanced techniques.

Rating based on required solving techniques: Tough
My personal rating based on actual solving: Hard

The first one is REALLY Hard
It took me more than 4 hours :oops:
But I really enjoyed it :) you have to jump in and out of the clueless!
The solution is

Be careful what you wish for! :wink:

When solving it I also had to do far more jumping between the grids than usual, but it did not take me that much longer than usual :D
My personal rating based on actual solving being Hard is because of all the jumping between the grids.
