🚂 Branchline
0:00
🎉 Line complete!
How to play
- Lay one continuous track from one tunnel to the other — no branches, no crossings, no dead ends.
- Each number says exactly how many cells in that row or column contain track. Every number must be matched — not one more, not one less.
- Drag across cells to lay rails. Pieces on bolted plates are pre-laid and fixed.
- Click a piece to remove it · click an empty cell to mark ✕ ("no track here") · right-drag to erase.
- Numbers turn green when matched and red when overshot. When the line is true, the train runs! Z undo · N new puzzle.
