For anyone doing these make sure you save after ever puzzle or it wont pop the achievement.
Nevermond12 12 Jan 2020 05:37
I'm saving after each puzzle, but sometimes cheevos just don't trigger.

Picross? PICROSS!!!

After logic, intuition, random guessing, and plain old luck, I'm down to one unsolved puzzle... Very Hard #33.
TheJ5333 27 Feb 2022 06:01
Do these in order! I've endured such pain from skipping puzzles, had to redo so many...did them legit the first time, then used solver when I had to redo like 30 Very Hard puzzles; no guide exists online, if ya need help let me know, I may just make a guide soon. In particular the last achievement on each difficulty seems to require doing the puzzles in number order for the achievement to trigger

How to earn achievements. You MUST save the game after completing 9 puzzles (so 21-29) After completing the puzzles it asks "Do you want to save" you MUST say yes. Then complete the 10th puzzle and save again. That should unlock the achievement. Very annoying. This can be done in one session or multiple session (Choose the "continue game" option, it's the second one on the screen with two options). If you saved when you had 8 or less puzzles, and then save when you have 10 puzzles the achievement will not unlock.

Oh and do not save while in a level. (That won't work for the 9/10)

Sounds like this has been fixed based on my ticket! Thanks Devs.
