Tuck (Mind Loft)

Tuck is a word building puzzle on Mind Loft, a free site of daily browser games. Each day everyone gets the same rack of 14 letters, weighted like a standard word game set (15 in the Sunday Edition), and an empty 9x9 board. There is no hidden answer. You design your own interlocking grid, and chasing the score is the puzzle.

Every run of two or more letters, across and down, must be a dictionary word, and the whole build must connect into one grid. Letters at intersections score in both words, so placing high-value letters where words cross pays. Using every tile on the rack earns a 10-point bonus.

Each day comes with a benchmark set from how players actually score on that rack. Beat it and the day counts as a win; roughly a third of finished grids do. On the day we looked the benchmark was 54. Scores use standard tile points across all your words, and ties break on fewest unused tiles, then the clock. Only your first submitted grid counts on the daily leaderboard.

A fresh rack goes up at midnight US Eastern Time. It suits players who like the board-building side of Scrabble without an opponent, and pairs with Mind Loft's Crux, Garble and Stet.
