Do you like numbers and loops? Of course you do! You're only human. Conceptis, the team who brought pencil puzzles like Link-A-Pix and Nurikabe to the web, are continuing their trend of porting their browser puzzles to the iOS platform, trading in the scratch of a pencil or the click of a mouse for the tap of a finger. Their latest App Store addition is Conceptis Slitherlink, a mobile iteration of their loopy logic puzzle Slitherlink Light.

Conceptis offers a variety of logical challenges at its website available to anyone. Eleven different puzzles await the intrepid solver, including familiar puzzles like Sudoku, Picross (here called "Pic-a-Pix"), Kakuro, Slitherlink, and a variety of puzzles that might even be new to logic puzzle lovers.

Slither Link by Luke Harrison will tickle the fancies of you logic puzzle fans out there. While Luke gets the credit for making this polished Flash version of Slitherlink, the actual puzzle was invented by the Japanese publishing company Nikoli. Nikoli is also known for popularizing Sudoku, and publishes a number of other similar logic puzzles.
