The red dots separate the row or column into two numbers (read from left to right or top to bottom) that use all the digits and are in a ratio of two to one.
Black dots separate digits in the ratio of 2:1 and white dots show a difference of one between cells.
Not all dots are given

That was a delightful puzzle, the first one for me with that mechanic. I got my first complete row/column narrowed down and had to draw out only two plausible options before figuring out which was correct.

The set of numbers allowed by red dot is limited - 12 combinations. But I am not sure how to write them all down without running a simple script on my PC. So, my question is whether you expect the user to do it or there is a logic path without having this info? To which variant you assigned 2* difficulty?
hi Deltameth, thanks for doing our puzzle. of course we are happy for people to solve it however they want but it might be more fun to do it by hand. There is plenty of logic to help out eg what is the start of the big number and how does it end, certain numbers can only be in one of the two and certain in the other (24589 have constraints). Then you have the kropki dots which narrow it down. hope this helps billybeth
