Hashi

Hashi also know as Hashiwokakero and Bridges is a logic puzzle played on a grid where you connect islands with bridges based on number clues from 1 to 8. You can play it on you iPhone, iPad, or iPad mini.

How To Play

Construct bridges between islands such that each island has the proper number of bridges attached to it.
Bridges can placed in a horizontal or vertical orientation and may not overlap.
You can have at most two bridges directly connecting one island to another.
The network of bridges must connect each island to every other island. In other words, if you pick any island in the puzzle you should be able to "walk" from it to any other island by travelling over the bridges.

It couldn't be much simpler than that. And yet, hidden behind these simplistic rules you'll find some devilishly challenging puzzles. Or, if casual puzzling is more your speed, the small puzzles will nicely satisfy your cravings without tying your brain in knots.

Speaking of brains, Hashi includes a Daily Challenge to keep you mentally sharp. The Daily Challenge tracks your best score over different time periods allowing you to compete against a very worthy adversary: yourself.

I'd put it in the same category as sudoku. Great puzzles at all levels. The daily challenge is a great bonus too. -D235680964

This is a lot of fun. My son had these for a school assignment and now I play them for fun. -Pamsss
