This is an application that lets you enjoy "Slitherlink" puzzles, famous from the puzzle magazines.

Slitherlink is a logics puzzle similar to Sudoku, where you have to think carefully to solve each puzzle bit by bit. There are only two simple rules: "connect the dots to make a circle" and "the number of lines has to match the number on the board".
While the premise is simple, it's also full of depth and you'll be surprised by the many different ways you can solve the puzzles.

This is the perfect application for people who want to keep their brains in shape, or spend some high quality time. Do give it a try!

Full of High Quality Puzzles
The problems contained in Slitherlink have all been created by professional puzzle makers. You won't find any of the unfortunately typical problems of other puzzle games, such as bland computer-generated puzzles that have more than one solution, verbose hints and require too much trial-and-error. Each puzzle is carefully hand-crafted to be as enjoyable as possible.

Download Additional Puzzle Packs
When you've finished all the puzzles that come with the application, there are still more puzzles out there for you to solve! At the moment, there are over 100 additional downloadable puzzles with an estimated play time of over 80 hours for amateur players, or 20 hours for intermediate puzzle-solvers. More puzzles are also constantly being added.

Pleasant Controls
We gave our utmost to create a very pleasant and easy-to-use control system. You can choose between three different control systems: a simple and easy to use tapping mode, a drawing mode that lets you use your finger as a brush, and the reliable flick mode, which has very few mistaken inputs.

Welcoming to Beginners
The first time you play Slitherlink, an easy-to-understand tutorial will appear and explain how the game is played. There is also an answer-checking function for those big-board, complicated puzzles.

Good, but...


Slitherlink is a fun puzzle, and this is an excellent implementation of it, with a nice clean interface and plenty of puzzles available. However, the banner ad at the bottom of the screen is intrusive and annoying. Please consider removing it, at least for customers who have purchased one or more of the paid puzzle packs. Having paid $3, I feel I should not have to look at a banner ad any more. I will happily re-rate this game at 5 stars, if this change is made. I would also encourage the developer to consider making a similar app for Nurikabe, another puzzle in this genre that I enjoy even more.

Could be great...but isn't


I agree with the other reviews. The ads at the bottom are annoying as hell and THERE IS NO WAY TO TURN OFF THE SOUND. The built-in ipad volume controls have no effect. The game gives you a loud CLICK every time you make a change to the puzzle, and you're stuck with it. Forget about playing in bed while your partner falls asleep - unless they're deaf, I suppose. I love slitherlink puzzles but i have no desire to ever launch this app.

Remove the ads


This is the best slitherlink app so far and I'm enjoying it but it's sullied by ads. I'm with the other reviewer; remove them and I'll gladly raise my rating. Game Center achievements would be nice. I would also love to see more Nikoli puzzles if the developer is capable, especially Yajilin and Heyawake
