Daily 1 to 25

1 to 25 is a puzzle by Andrew Stuart and Jeff Widderich, the pair behind Str8ts, and its Daily '1 to 25' Puzzles page on str8ts.com gives four puzzles to play online, with a timer, a restart button and a printable version. The four boards change every day and carry that day's date, and the player keeps your progress if you leave and come back.

The board is a 5x5 square surrounded by a ring of numbered chevrons. Each number from 2 to 25 sits on the ring and points the way it can move: numbers on the left and right edges go into their row, numbers at the top and bottom go into their column, and the corners point diagonally across the board, so every number has only five possible squares. One number starts on the board.

The second rule is the chain: each number must sit next to the one before it, above, below, beside or diagonally, so that the finished board snakes from 1 to 25 without a break. You click a number on the ring to slide it along its line, or type numbers into the squares.

It suits players who enjoy Hidato, Numbrix and other number-path puzzles, and anyone who already plays the daily Str8ts and SudokuWiki puzzles from the same makers.

The page is free to play with no account. It has no adverts in play; a Buy Me a Coffee button asks for support, and a sign-up link offers more puzzles by email.
