LetterLinks

LetterLinks gives every player a daily rack of about twenty letter tiles, each with a point value in its corner, and a five by five board scattered with double and triple letter and word squares. You place tiles to form words reading left to right or top to bottom, like Scrabble: every word must be at least two letters long, all tiles must connect, and one tile must sit on the centre star before you can submit.

Some racks include wild cards, marked with a star, that can stand for any letter, and some days bring bonus tiles that double the score of the word they are in. Tapping the gift icon shows the day's bonus challenge, a word pattern that earns 1.5 or 2 times the points. When you submit, invalid words are highlighted in red, and your score counts toward a skill level shown beside it.

You can drag tiles or tap to place them, shuffle or clear the rack, and see a leaderboard and yesterday's best board. Once today's game is done, a countdown shows when the next daily challenge opens at your local midnight; the rack and the layout of bonus squares are built from the date, so everyone playing on the same day gets the same ones. It is free in the browser with ads, and suits Scrabble players who want one compact board a day.
