Play the Letterbox Game by placing letters one at a time into the 4 by 4 grid to make as many 3- and 4-letter words as you can — across and down.

Random letters appear in the box at the top of the display, near the Next button. Click/tap in any vacant square of your playing grid to place the letter. You can try it in different squares and, when you're happy with where you've put the letter, use the Next button to lock it in and get the next letter.
