Today LinkedIn is launching a new daily game, Zip, which is their third logic game alongside Queens and Tango where we’ve helped design/edit the puzzles. Zip is a path-drawing game with simple rules: draw a path through all cells starting at 1, going up in order, and ending at the highest number. Some puzzles have a fully open grid while others, like this puzzle, include walls to embed different logical and visual themes.
