Bookworm Nintendo Game Boy Advance

Bookworm is one of the classic office time-killers, right up there with downloading the latest Hugh Jackman trailer and playing trash-can basketball. Now this wildly popular vocab-stretching game gets the GBA treatment!

Like all great brain teasers, the idea is simple yet elegant; spell words using a screen filled with scrambled letters. You can only connect adjacent letters. The longer the word, the more points you score.

Bonus words are also served up to prove your the cunning brain box you like to think you are, but watch out, dangerous fire tiles fall with every word you spell. Fail to use them before they reach the bottom of the screen and you'll be an inanimate husk of the Anatidae family. That's a dead duck to the rest of us.
