CSM writes: "Bookworm is a downloadable wordsearch puzzle game for the Nintendo DSi. Players need to look over a board of letter tiles and connect adjacent ones to spell out words. When those chosen tiles disappear, new ones fall in to take their places. As play goes on, special tiles come into play: bonus tiles that will multiply the number of points for a word, and fire tiles that must be used before they reach the bottom of the screen (or else the game will be lost). The titular worm, who stands at the side of the gameboard, often defines words the player has just spelled."
