Rackle

Rackle starts from a rack of letter tiles, like a word board game, and asks you to use all of them. You drag or tap tiles onto a 7x7 board to form words that read across and down and join into one connected grid of at least three words. Every word must have three or more letters, so two-letter joins do not help. There is no single right answer: any grid that uses every tile and connects is a solution.

You get five attempts at the day's rack. Scoring rewards finishing in fewer attempts, and a Perfect Word bonus goes to a grid that includes one continuous 7-letter word. Your streak, stats and best daily score are kept in the browser, with no account needed to play.

The puzzle is numbered and changes at midnight UTC, the same for every player, with a countdown to the next one on the page. Solving it lets you join that week's leaderboard under a username; once you have played, you can replay the day's rack for practice without it counting. Rackle was created by Jay.

It suits players who like building words rather than guessing them, in the spirit of a small daily crossword you design yourself from a fixed set of letters. The page is clean and plays the same on a phone, with the rack below the board, as on a desktop.
