Hints for Zip #591

CheckCheck the path you have so far

Draw the line you have in the game, then press Check. We tell you how much of it is right and where it first goes wrong, without showing the rest. Still stuck? “Next move only” adds one correct step.

The checker needs JavaScript.

Hint 1Forced moves

Some cells have only two ways in or out, so the path has to use both. These 16 links are certain before you draw anything:

Hint 2The first stretch

Start on 1. From 1 to 2: right 1; from 2 to 3: down 1, left 1, down 2, right 1.

Hint 3Halfway

Here is the path from 1 up to 5, about half of the board. The rest has to sweep the cells that are still empty.

How to solve Zip #591, step by step

Our solver walks the answer from 1 and, at every turn, checks why the other ways fail. The darker line is the stretch each step adds; dashed circles mark where there was a real choice.

Show all 7 stretches (this gives the answer away)

From 1 to 2: right. The real choice is at row 2, column 2: going up or down or left looks open, but every way on from there gets stuck before the board is full (a dead end, a cut-off area or a number out of order), so the line goes right.
From 2 to 3: down, left, down 2, right. The real choice is at row 2, column 3: going up looks open, but every way on from there gets stuck before the board is full (a dead end, a cut-off area or a number out of order), so the line goes down. 4 more choices like that follow in this stretch.
From 3 to 4: up, right, up 2. The real choice is at row 4, column 4: going right looks open, but every way on from there gets stuck before the board is full (a dead end, a cut-off area or a number out of order), so the line goes up. 1 more choice like that follows in this stretch.
From 4 to 5: right, down 3. The real choice is at row 2, column 5: going up or right looks open, but every way on from there gets stuck before the board is full (a dead end, a cut-off area or a number out of order), so the line goes down. 2 more choices like that follow in this stretch.
From 5 to 6: down, right, up 5, left 2. The real choice is at row 5, column 5: going right looks open, but every way on from there gets stuck before the board is full (a dead end, a cut-off area or a number out of order), so the line goes down.
From 6 to 7: left 3, down 5, right 2. There is only one way through: every other move is blocked by a wall, the edge or the line itself.
From 7 to 8: right, up. There is only one way through: every other move is blocked by a wall, the edge or the line itself.

Inside Zip #591

What our solver found when it checked this puzzle.

No walls. The numbers and the edges of the board are enough to fix the path.
Spare numbers. You could remove the 6 or 7 (any one of them) and the path would still be the only one. The 2, 3, 4 and 5 are essential.
Longest stretch. 6 → 7 takes 10 moves.
