How to Play LinkedIn Zip

Rules

• Start at dot 1.
• Visit the numbered dots in increasing order.
• Pass through every cell exactly once.
• Move up, down, left or right, never diagonally and never through a wall.

How the game works

Drag from dot 1 to draw the path. You can move up, down, left or right into any empty cell that is not blocked by a wall. The puzzle is solved when the line has visited every dot in order and covered the whole grid.

Beginner strategy

• Corners have only two neighbours, so a path through a corner must use both.
• Never leave a pocket of cells the path can no longer reach.
• Look at what each dot forces: a dot in a narrow spot often has only one way in and out.
• Count the cells between two dots; the route has to use them all eventually.

Common mistakes

• Racing ahead from dot 1 and cutting off an area.
• Planning a diagonal move that the game does not allow.
• Forgetting walls when planning a shortcut.

Example

Here the path snakes through the grid row by row, reaching dot 2 and dot 3 in order and covering all 16 cells.
