- New user interface design.
- Night mode bug solved.
- Other minor bugs solved.
You are given a grid of squares, some of which are filled with train tracks.
You need to complete the track from A to B so that the rows and columns contain the same number of track segments as are indicated in the clues to the top and right of the grid.
There are only straight and 90 degree curved rails, and the track may not cross itself.
