PathFolding

PathFolding is an abstract strategy game. The aim is to fold the longest path around the red circles by connecting the blue ones. Every connection to a circle brings one score point.

The allowed connections are vertical and horizontal, not diagonal. A connection fails if it starts from a blue circle and there are red circles in between. A red circle will be replaced by blue one when the path replaces blue circles on the right, left, up and down. The elimination of the red circle with "10" mark will bring 10 score points. For the iPhone version the user has an option to replace a red circle for a blue one by double-tapping, with a cost of -10 score units for the first time, -20 units for the second time, and -30 units for the third time.

Path crosses are allowed. Every cross brings one score point.

To enter a new level connect with the green circle. If a connection is formed through the green circle, no new level is possible.

At the end of current level the red circles that are adjoined by at least one of the blue circles (right, left, up or down) will appear at next level together with new red circles. Otherwise, at a new level, only new red circles will appear. The game is over when the next level is not possible because of the high number of red circles.

Note. The app is not optimised for 4-inch first-generation iPhone SE.
