Play the Flash game "Bookworm" online by visiting the developer's website, PopCap.com, accessing the game's page and launching the free Web version. The game is also available to play through online gaming portals such as MSN.com, Games.com and Zylom.com.
To play "Bookworm" on PopCap.com, navigate to the All Games section of the Games menu and select "Bookworm" from the available list. This loads the game's page, which contains options to play the game online as well as download the full version. Other sites feature a similar interface, where the game has a separate page that allows access. Some sites launch the game in a separate window, rather than embedding the game in the same page.
The controls for the game involve clicking on different letter tiles to move them across the board in an attempt to form different words. When you feel that you have a valid letter combination, click the Submit button to test the word against the game's internal dictionary and remove the tiles from play. If the word is valid, you also earn points. Some tiles feature an image of an explosion; if these tiles make it to the bottom of the grid, the game ends.
