Games like Flow Free: daily connect-the-dots pipe puzzles

The closest matches come from Flow Free's own makers, Big Duck Games. Flow Free: Bridges adds squares where two pipes may cross, Flow Free: Warps lets a pipe leave one edge of the board and come back on the other, and Flow Free: Hexes moves the rule to a hexagonal grid. Each has its own Daily Puzzles pack that changes every day, with a varying number of boards and a streak for playing on consecutive days, and all three are free with ads on iPhone and Android.

In the browser, Flowku on Puzzleship is the plain Flow rule with six numbered grids a day, from very easy to ultra hard, and an archive of past days. The Daily Mail's Colour Connect posts one dated board a day for its readers. Several newspapers outside the English-speaking world run the same rule with menus in their own language: Circuitos from La Nación (Spanish) and Circuitos from O Globo (Portuguese) each give an easy, a medium and a hard board a day (La Nación asks you to log in for past days and its ranking), and Kropki on the Polish site Łamaniec has one board a day with an archive. The rule is the same in each, so the language barely matters once the board is open. On iPhone, Daily Connect Puzzles from Gamenight Games includes a daily Dot Connect beside a Nonogram and a Ball Sort; the app is free to download and offers an optional monthly subscription. Numberlink on PuzzleMadness swaps colours for numbers: link each pair of equal numbers with a line so the lines fill every square, with a new grid each day at several sizes and scores on a leaderboard.

A few games change the board itself. LINKR gives three numbered boards a day where the dots sit on a network of lines rather than a grid, and every point must be used. LYNE, a paid game for PC, Mac, phones and Switch, draws one path per colour through shapes and numbered nodes, and releases a new set of generated puzzles each day. Chromaflow turns the idea around: the path pieces are already on tiles, and you swap and rotate them until every colour joins its endpoints, at easy, medium and hard each day. PipeConnect on PuzzleMadness hands you a counted supply of pipe pieces to lay so that all bulbs of one colour join up. PipeTurn, on the same site, fills the grid with pipe tiles already in place, and you turn them until each colour's bulbs are joined and no two colours touch.

Not every game called Flow follows the Flow Free rule: Flow from the Tages-Anzeiger draws a single line through numbered dots in order, closer to a number path puzzle than to colour pairs.

If you want more Flow exactly as it is, start with Flowku or one of the newspaper Circuitos boards in the browser, or the Flow sequels on your phone. If you want a daily habit with a new wrinkle, try LINKR or Chromaflow. Every daily game whose own puzzle is a path, loop or pipe network is on the daily path and loop puzzles page (https://dailygamestoplay.com/daily-path-puzzles).
