Each puzzle consists of a grid containing clues in various places. The object is to create islands by partitioning between clues with walls so that the number of squares in each island is equal to the value of the clue, all walls form a continuous path and there are no wall areas of 2x2 or larger. Each island must contain one clue and be isolated from other islands horizontally and vertically.

The game features a highlighting option to help see if a wall segment is about to become isolated, and an island size counter to view how many squares belong to an island.

Great game
JCSanford

Free app with a generous number of free puzzles. No ads. Reasonably priced add on packs of puzzles. More puzzlers should strive to be like this.


Excellent interface
Math teacher in WA

Excellent interface, very usable. The hard puzzles are actually hard. Suggested improvement: let me use a second color to pencil in a possibility and then erase it or make it black.

One of my favorites

This is just a great way to relax and stretch the mind a bit. It would be nice if there was the ability to drag the current pattern.


Love it

My fave!


Wonderful puzzle
Kdausman

Just like this company’s other offerings, this puzzle game is spectacularly-implemented and rich with content! I especially appreciate the weekly puzzles. My only complaint (which is very minor) is that all of the company’s offerings seem to synchronize the weekly puzzle difficulty level, so on a week that is designated “very easy,” all of them are very easy, and so I have no challenge.


Affordable entertainment

New free puzzles weekly and new paid puzzles faster than I can solve them. Great.
