How to play the train tracks puzzle
- Slide your finger across the grid to draw rails. Curves and straights follow your finger.
- Tap next to a rail end to extend the line. Loose ends join nearby track by themselves.
- Mark cells you know are empty with ×, or erase anything with one swipe.
- Undo and redo as much as you like.
Train tracks puzzle strategy
1. Clear the zeros
A row or column marked 0 has no track at all. Mark every cell in it as empty first.
2. Fill the full lines
When a number equals the number of cells still open in its line, every one of those cells holds track.
3. Follow the stations
The line starts at A and ends at B, so the track next to each station must continue into the grid. Count which neighbours are still possible.
4. No dead ends, no loops
Every piece of track joins exactly two others, except at the stations. A cell that could only connect one way cannot hold track, and the line may never close into a loop.
5. Mark empty cells as you go
Each × you place lowers the options in its row and column, which often completes another line.
