Trace a word
Press on a letter and slide through its neighbours, up, down, sideways or diagonally, then let go to play the word. A tile can be used once in each word, and a word needs at least three letters. As you trace, the word appears above the board and turns green with its points when it is one you have not found yet. Slide back over the previous letter to take it off. With a keyboard, simply type the word and press Enter; the board finds the trail for you.
Ninety seconds, one goal
Each board has a points goal, and the clock starts when you uncover the letters. Three- and four-letter words score 1 point, five letters 2, six letters 3, seven letters 5 and eight letters 11. Reach the goal before time runs out and the next board is yours, with a slightly higher goal. Fall short and Retry brings new letters with the same goal. Every word after the goal still adds to your score. Pause, or press P, covers the letters while you take a break.
