Hashi are addictive bridge-connecting puzzles which were invented in Japan. Using pure logic and requiring no math to solve, these fascinating puzzles offer endless fun and intellectual entertainment to puzzle fans of all skills and ages.

Each puzzle is based on a rectangular arrangement of circles, where each circle represents an island and the number in each island tells how many bridges are connected to it. The object is to connect all islands according to the number of bridges so that there are no more than two bridges in the same direction and all bridges are interconnected enabling passage from any island to another.

To create a bridge simply swipe your fingertip between two islands. The game also features highlighting options, helping see in which directions bridges are allowed and whether an island segment is about to become isolated.

For more fun, Conceptis Hashi includes a Weekly Bonus section providing an extra free puzzle each week.

Customer Reviews

This is an exceptional game

This is an exceptional game and I can't stop playing it. I have both the iPhone and iPad versions and the puzzles are different on each. It's mathematical and logical but the choices continuously change as you make more bridges. I have found no issues with the grids. The interface is very well designed and just a pleasure to use. I am up to the Very Hard ones now. I hardly ever purchase games but I have already bought additional sets and will almost surely buy more. I have recommended this game to my friends and some of them weren't thrilled, and I realized they had downloaded different games. This game by Conceptis is definitely the one to get. I will be playing this game for a long time.

Has glitches

Good game- makes you think a bit, that's nice. Gets progressively more difficult- also nice. Main glitch: there's more than 1 solution to some puzzles, and even though I've solved a puzzle correctly, I'm occasionally told there are errors. It'd be nice if the developers had more than 1 solution programmed for the puzzles. Also would be nice if I didn't have to go back to the main menu to pick the next puzzle when I complete one. That being said: AWESOME FREE GAME.


as has been already noted Hashi puzzles are really a lot of fun and are mentally challenging. I have been using this app off and on for a few years. It's a great app. Any flaws that I've come across are minor.
The biggest problem is there aren't enough games. even though you can buy extra games at a reasonable price, you soon run out of puzzles to do. The addition of the weekly free puzzle is nice, but more puzzles are needed.
