Games like Zip: daily one-line path puzzles

Zag, from Puzzleship, is the closest match: one continuous path through every cell, passing numbered checkpoints in order, with six grids a day from very easy to ultra hard. Tiny Maze drops the numbers and adds walls, so you find the one route from door to door that visits every cell. Bean Connect is a single timed path through every bean from a starting point, a good quick swap for Zip.

If you like the filling more than the order, the coloured-dot games are next. Flowku joins pairs of dots with paths that must cover every cell, and Flow Free has a daily pack of boards in the app; La Nación's and O Globo's Circuitos post three levels of the same puzzle each day in the browser.

For a step up, the classic loop puzzles ask for one closed route drawn from clues: Daily Masyu with its black and white pearls, and Daily Slitherlink with numbers that count the loop's edges. Lawndle turns the idea into a little game, mowing every tile of a lawn in as few steps as you can.
