Bookworm (by PopCap)

Bookworm is a word-forming puzzle game by PopCap. From a grid of available letters, players connect letters to form words. As words are formed, they are removed from the grid and the remaining letters collapse to fill the available space. The bigger the word formed, the better the bonus. But watch out for burning letters — they could spell disaster. If you need a quick word break, link letters fast in Action mode. If laid-back wordplay is more your style, go with Classic.
