How to solve a Crossword on your device:

Enter letters just by typing them in. On phones without a keyboard or number pad, enter letters by pressing the Soft Key to bring up a keyboard, then select the letter you want to enter and hit OK. You can also use the arrows on the keyboard or your trackball to navigate the grid. On devices with keyboards (like blackberries), press to skip to the next word and the SPACE bar to switch between Across and Down. To jump to the next word, press ALT and use the trackball. On devices without keyboards, use '#' to switch between Across and Down. To jump to the next word, press '*' and use the UP, DOWN, LEFT, and RIGHT.

From the menu, you can select VIEW CLUES to see the clues and the answer squares up close. You can move around the same way as in the grid. You can zoom out for a better view of the whole puzzle too.
