Introduction
I hope you enjoy this set of somedokus I put together! If you're interested: I thought if setting such a puzzle is even possible and had a lot of trouble even setting a single one. After I managed to get a 6×6 to work (puzzle #3), I decided to try to get a computer to generate some more. After getting the numberlink generator by thomasahle to work for me, I combined it with a somedoku- and product band solver I quickly coded and was surprised by it working instantly. Most puzzles it generated, were not very fun to solve though. But after solving dozens of puzzles, I managed to find 3 more that I like! :)
Rules
  • Somedoku:
    • Fill each cell with a digit from 1 to the grid size. Each row n and each column n must contain exactly n different digits, with repetition allowed as necessary.
  • Numberlink / Arukone:
    • Connect same shapes with continuous, orthogonal lines passing through the center of each cell. The lines may not cross or split.
  • Product Bands:
    • The product of the digits on two of the same shapes must equal the sum of the digits on the line connecting them.

Solution code: The last row of all four puzzles from left to right (21 digits).

The instructions for the solution code in German are wrong - last column instead of last row.

I don't know how that mistake managed to slip in, thanks for pointing it out. It's fixed now. :) -Elytron

Only gotten through 1 and 2 so far. This is quite fun, but challenging!

It would be helpful to have an example for Somedoku rules, like "row 1 might contain only 3s, row 2 might contain only 2s and 4s, etc."
