About Train Tracks
Play the Train Tracks puzzle online for free. Connect the entrance to the exit with one unbroken rail line, using the number clues along each row and column to work out exactly which cells the track passes through. Pick the exact rail piece from the palette — straight or curved — and lay it down, cell by cell.
How to play Train Tracks
- Pick a rail piece from the palette — straight or curved — then tap a cell to lay it down.
- The track must form a single unbroken line from the entrance (A) to the exit (B), with no branches, loops, or crossings.
- Each row and column clue shows exactly how many of its cells the track must pass through.
- Placing a piece that would break a row/column count, or doesn't connect correctly at an entrance or exit, costs a life instead of landing — use Undo or the eraser to fix a mistake.
- The puzzle is solved when the track connects A to B and every row and column clue is satisfied.
Tips & strategy
- Start with rows or columns whose clue is 0 — you know immediately that no track cell can go there.
- A clue matching the number of cells already fixed in that row or column tells you the rest of that line is empty.
- Work from both the entrance and the exit toward the middle — they're often the most constrained parts of the grid.
- Use the ✕ mark tool to flag cells you're sure are empty — it keeps the grid readable without spending a life on a guess.
