Connect bridges between islands to form one interconnecting path! 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. To help see the puzzle progress, graphic previews in the puzzle list show the progress of all puzzles in a volume as they are being solved. A Gallery view option provides these previews in a larger format. For more fun, Hashi contains no ads and includes a Weekly Bonus section providing an extra free puzzle each week.
