It looks like a dot-to-dot, but there is a catch. Number Path unblocked asks you to draw a single line through a small grid, visiting the numbers in order, and the line must pass through every square exactly once.
The puzzle is part of Tejas Wavde's open-source set of browser games. Boards are built on the spot starting from a finished route, so every puzzle can be completed.
How to play Number Path
Start on the square marked 1 and drag through neighboring squares. You can move up, down, left or right, but never diagonally. If you prefer, tap squares one by one to add them to the end of your line.
You have to reach the numbers in their exact order. Moves that hop past a number out of order, leap away from your line's tip or pass through a wall simply won't take. Walls show up as thick bars between some squares on the bigger boards.
The board is solved when your line fills every square and ends on the highest number. Easy, Med and Hard change the grid size, and each size opens on a daily board. Press new for a random one.

Tips
- Start with the corners. A corner square has just two neighbors, so the line almost always enters on one and leaves on the other.
- Don't trap empty squares. If your line walls off a pocket of squares, you can't get back in. Check before each turn.
- Plan the ending. The line has to finish on the last number, so work out the last stretch of the route early.
- Treat walls as clues. A blocked edge removes an option and often forces the route around it.
- Cut back instead of resetting. Tapping a square already on your line trims it back to that point.
Number Path questions
Why is the first board the same every time?
Each size starts with a daily puzzle tied to today's date, so it stays the same until tomorrow. Press new whenever you want a fresh random board.
Is there only one right answer?
Any line that starts on 1, visits the numbers in order, covers every square and ends on the last number counts as solved.
Can I play on a phone?
Yes. Drag a finger across the grid or tap one cell after another. The board resizes for small screens, and undo and reset sit underneath.
