These words may be etched in stone, but that doesn’t mean they can’t be changed!
Move your mouse to highlight a column, clicking the block at the bottom of it to pick it up or swap it with the one you’re holding. Click an empty space at the end of a column to place a letter. Create words in rows or columns (when a word is recognized, it will be highlighted), and then click Submit. You get extra points for creating the words listed to the right. When the timer bar fills up, a new row will be added. Click the timer to request a new row early. When the dragon fills up, you will go on to the next level. Don’t let the letter tiles reach the line at the bottom of the screen.
Good Luck and Have Fun.
