In the game, you will use your fingers to swipe between two islands, one at a time. The aim is to connect all the islands in such a way that there are no more than two bridges in the same direction and all bridges are connected.
To do that, you will have to form certain patterns of circles and lines. For example, a bridge can be made by connecting three circles in a line. The number in each circle tells you how many bridges are connected to it.
Once you are done, the next puzzle will be displayed. If you are ready to play the next puzzle, tap on the puzzle list button and choose the Hashi puzzle you want to play.
