User reviews

Imperfect but good and free

I tried half a dozen slitherlink games, and all of them were useless—either there’s no generator for new games beyond the couple dozen it comes with, or you have to wait for “stamina” to play for new games, or you’re bombarded with ads, or there are glitches that make it unplayable, or the interface is unusable. Then I found this one. No unnecessary “gamification”, no timers, just pick it up and play a custom slitherlink whenever you want. The interface doesn’t scale well as you play larger puzzles and it has to shrink everything down (it starts to shrink beyond 10x8 on an iPhone 11, but the cutoff probably depends on your device, and how far it can shrink before it becomes too annoying probably depends on your eye and fingers). A few of the color schemes (which it randomly selects each time) are pretty low-contrast. But those are the only problems I’ve found, and they don’t negate the fact that this stands head and shoulders above every other slitherlink app I’ve tried in that you can actually have fun playing it.

見づらい

囲い線を書いたのか、まだ何もしていないのか、ぱっと見で分からない感じです。 レベルによって色が変わるのですが、7×7、10×10は見づらくて、ギブアップしました。 同系色というか、黄緑と青緑で囲い線か未処理の場所かを見分けるのは、難しいです。 良く見れば分かりますが、繋がっているか一瞬分からず、あれ?ってなる事が多いです。 もう少し色を変えるか、線を太くして欲しいです。

Very poor colour.

I’m sure it’s ok to play but the colour scheme is quite ludicrous. It’s very difficult to distinguish where you have placed a line and in harder puzzles this is going to become an issue.

Clean, Intuitive, Infinite

I only discovered what Slitherlinks were earlier this year. I loved playing them online and downloaded a few apps at the start. This is the only one I’ve kept. I’ve solved all the puzzles and since there’s a generator in this app, I have an infinite number of more puzzles.

The UI is simple but pleasing and I haven’t run into any bugs or glitches after months of using this app almost daily.

While I like the colors used, I do agree that some of the colors are very similar (like the purple theme) and make it hard to tell the difference between the background and your selected lines. The opacity of the background color should be set low for all the themes.

I’m a big fan. Thanks for sharing this!
