About Number Chain

Number Chain is a path puzzle. Some numbered circles are already on the grid. Starting at 1, drag a line through every square so that you pass the numbers in order — 1, 2, 3 and so on — and end on the last number. Every square must be used exactly once, and the line can't cross itself.

How to play

1. Press on the circle marked 1 and drag through neighbouring squares.
2. Pass the numbered circles in order: 2 next, then 3, and so on.
3. Fill every square and finish on the last number.

Tips

Look at the corners first — a corner square only has two ways in and out, so the path is forced there.
