Drag Letters from the Tile Set and drop them onto the empty squares on the Grid.

Fill the Grid so that every string of Letters (down and across) of length two or greater is a valid English word.

If a Letter is involved in an invalid word, it will appear red. Otherwise, if the Letter is involved in a valid word, it will appear green.

Certain levels may have additional Challenges active. Look for additional icons in the bottom-left, and press them for a list of each active Challenge.
