How to play Zip
Three rules. That is the whole Zip game, the same ones LinkedIn Zip uses.
1. Start at 1
Press and drag from the cell marked 1. Keyboard players can also use the arrow keys.
2. Hit every number in order
The path must pass 2, then 3, then 4, and so on. Empty cells between numbers are allowed. In fact you must use them, because the Zip game also requires a full grid.
3. Cover the whole grid
Visit every cell exactly once. Dark bars are walls; the path cannot cross them. Drag backward to erase, or use Undo and Clear under the board.
