Zip game # Zip game, the daily one-line puzzle, with no ads > Like the LinkedIn Zip game? One Line in Crux is a daily path puzzle: start at 1, pass every number in order and fill every cell with one line. Free, no ads. Zip is the LinkedIn puzzle where one line has to pass through every cell of the grid and touch the numbers in order. [One Line](https://crux.quest/games/one-line/) in Crux plays the same way: start at 1, end at the last number, and cover every square without lifting your finger. There is a new board every day, the same one for every player, and no ads. Crux is made by Pizzart Pte. Ltd. and is not affiliated with LinkedIn. ## How to play One Line - **Numbered stops.** Trace a path from 1 to the last number, in order. - **Cover every cell.** Every square gets visited once. Do not lift your finger. - **Numbers light up.** Each number turns green as you pass it. Undo if you paint into a dead end. ## Tips for a Zip-style board - Start with the corners. A corner cell has only two neighbours, so the line can only pass through it one way. - Look at the gap between two numbers in a row. The line has to get from one to the next without cutting off a part of the board it still needs. - If part of the board can only be reached through a single cell, the line has to finish in there. - When you hit a dead end, undo back to the last number instead of starting over. ## More daily logic puzzles in Crux - ### [One Line](https://crux.quest/games/one-line/) Numbered Stops.
