Puzzle solve at most taxing difficulty

User reviews

My puzzle disappeared after I finished. 10+ hours of work gone

The first puzzle I ever did was a 20x20 pro hexagon grid. This was admittedly a mistake as I was a newb and mistakes were made, slowing down the process considerably. It took 10 hours, but I was really proud of myself for fixing all my mistakes and finishing. I didn’t realize the puzzle would just disappear once I was done, so I went to the main menu and now this thing that I spent 10+ hours on is just gone. This is incredibly upsetting. Honestly, I’m a software engineer and in not too much longer than the time it took, I could code my own slitherlink app, which makes the value of this one pretty low to me, definitely negative if I plan to use it to solve another large puzzle. I wish I had paid more attention to the rough corners before using this app.

Also bad for colorblind people. I’m colorblind and it really was impossible to tell red vs green numbers. I had to count the walls for each cell. Also errant touches would trigger false walls I didn’t mean to tap while I was planning around and there were a few puzzles that were ambiguous (more than 1 solution).

Pretty good, could be great

A couple suggestions:

Add an option to automatically X out lines that should obviously be X’d (like when I put a line next to a 1, X out the rest of the edges.)

It’s hard to tell when the puzzle is scrolled out to the side sometimes, so I end up playing like I’m on the edge. Some indicator (some blurring?) showing were not at the edge would be nice.

Nicely done

I was very impressed with this game. Zen like themes. Good range of challenges. No annoying ads! Happy to pay the 3$ to unlock all the levels. Thank you.

Hostile to color blind people

The game is really nice and clear. Except the color schemes are really difficult to read for color blind people.

Hard to see

Great game, wish they had different color scheme cause I’m color blind with the colors they use so it’s hard to tell which ones are wrong
