Numberlink (PuzzleMadness)

Numberlink gives you a grid with pairs of numbers. You draw a line between each pair, moving across or down through the squares. Lines cannot cross each other, cannot branch into a T, cannot double back to touch themselves, and in the end every square of the grid must be filled by some line. It is the puzzle behind games like Flow Free.

The daily page opens today's puzzle on its own, and its title carries the date (on 3 October 2026 it read "Daily Medium Numberlink Puzzle for Saturday 3rd October 2026"). There are four dated grids a day. Small, Medium and Large each have their own, and the Mixed page serves a fourth grid of its own (on 28 October 2026 they were 6x6, 11x11, 14x14 and 7x7). Past days stay in the archive, so a missed puzzle can be played later, and there is a print version and an image download of the grid. PuzzleMadness does not publish solutions: the site tells you when you have finished a grid correctly or made a mistake. Each completed puzzle adds to your total on the Numberlink monthly and all-time leaderboards, where only your best score on any one puzzle counts.

The rules page is honest that not every step is pure deduction, especially on bigger grids: you will often draw a likely line and adjust. Pairs on the edge usually hug the edge, and lines next to each other tend to run in parallel. Short pairs that are close together are usually connected directly.

PuzzleMadness is a British puzzle site with dozens of daily puzzle types in the browser, from many sudoku variants to logic grids such as Nurikabe, Hashi and Slitherlink. It is free to play and carries ads. A free account keeps track of the puzzles you have finished and puts your name on the leaderboards, and the badges next to usernames mark how many puzzles a player has completed.
