### 5/5 — Awesome app, just one question

*2025-01-29*

What are coins used for? I see no place to spend mine

**Developer response:** You can unlock the game packages with the coins, or get extra tips

### 5/5 — Request

*2025-01-18*

Can you update so the daily hexagon puzzle shows a tick when completed please?

### 5/5 — Great game

*2023-08-06*

It’s missing a few small features that other Slitherlink games have, but they’re not difficult to implement. The first is a bounding box so that the edges are clearly marked. Slitherlink strategy relies heavily on corners and sides, so adding this as an option will be great. 

The other is auto x. Showing possible lines is nice, but it’s a little too much visually. It seems like the game already knows where the xes should be, so having this as an option alongside possible lines would be a nice update (and both can also be on at the same time). 

As for why I downloaded this app when I have the other, it’s because I was looking for a version that has dark mode and drag to draw lines. While this doesn’t have the drag to draw, the dark mode is enough to make me switch and pay as long as the above are added.

Thanks for the nice app!

**Developer response:** Thank you very much for using our app and giving us valuable advice. Border and automatic prompt x will be available when the next version is updated, and the sliding input is more complicated. We are evaluating this function and trying to find a suitable way to implement it. Thank you again for your comment.
