Bookworm is an endless word-based game from PopCap, similar to Scrabble but in its own style.


A Bookworm.rsrc file in the game folder on Mac does not even mention Bookworm in any way, but instead mentions Bejeweled 2, a title that wasn't even known until a year after.

Revision List

To do:
Find 1.00 and 1.01 to document.

1.13 (2007, PopCap.com)

  • The game's executable was recompiled, having support for loading from a main.pak file, excluding reading a packed music directory, the developers never packaged the game assets since of this change so this wasn't shown off. This change was carried on in later versions.

1.13 (Final, PopCap.com)

  • The trademark over the game logo in the game's menu backdrop texture was removed.
  • The texture of the game logo on the title screen was redone.
  • The size of the PopCap logo on the game's title backdrop texture was shortened.

Command-Line Parameters

The game's executable mentions developer command lines for starting the game, it's not friendly with commands using spaces so use = instead, starting from this method forces the game to act like it's in "Trial" mode. These are:

  • -play: Plays popcap.dmo if it's present, if not present, an error is shown. -demofile can also be used to choose the name and location of the file.
  • -recnum: Records demos with Popcap.dmo and Popcap#.dmo if that's taken on every boot.
  • -playnum: Plays demos with Popcap.dmo and Popcap#.dmo from -recnum if that's taken on every boot.
  • -record: Records a demo named Popcap.dmo and saves after shutdown of the game.
  • -demofile: Specifies filename for recorded demos.
  • -crash: Crashes the game immediately with an Access Violation error.
  • -screensaver: Makes the game act like it's a screensaver, any movement or key presses will immediately force close the game.
  • -changedir: Changes game installation directory, for the current boot.
  • -version: Shows the product name, version, build number and build date with a popup instead of starting the game.
