Feel special this puzzle got me to finally register. this puzzle was tricky but very doable as long as you use your brain. very well done, probably just put together in a few seconds but worth it none the less. Tip/ the 2s are parralel to one another.
I agree that it is logical. It takes a bit of trial and error, but not guessing. You have to play with where to place the 3 in the first column. I think it probably took quite a bit of effort to make it so it was doable without being easy or guessy. Only thing is... I don't know what the heck it is. Is it anything?
The value for this puzzle for me was that I tried to put as many needs for trial (or advanced logical deduction) as possible in such a small place. It does not represent anything special (therefore "pattern"). But I used my nonogram solver (p a l o m a k i . d e -> Games) when creating this (although it does not support directly advanced logic, but I can use it well for trial/error).
Man, this was awesome! Jarmo, that was incredible of a puzzle! Trial and error does happen here, but it's so good once you figure it out! Amazing puzzle!
