Use these letters like Scrabble tiles to make or solve anagrams. Drag them one by one from the ‘palette’ and arrange them as you want in the lower part of the window (the palette contains 6 copies of each letter). When you click your browser’s Refresh/Reload button, the letters all go back into the palette.
