Maybe It Was due to that time during the incunabulum of my existence, when a rapscallion upturned a Scrabble board and my neonate form was showered with word fragments like some perverted sort of plastic precipitation, but I've always had a fascination with lettered tiles tumbling down the screen just begging to be herded into lovely locutions. Bookworm Deluxe is a logophilic's dream from Pop Cap, available on Steam. Trace a line of adjacent letters along a grid to form as an extensive a word as possible, see the letters disappear from the play area, and watch new uncial monograms fall in to replace them.
Avoid small words, as this coaxes burning letters into the playing field. These guys burn through letters beneath them, threatening to destroy the library you reside in, should they reach the bottom of the grid.
Where Bookworm Deluxe gets interesting is the moment you realise the regularity with which you're finding the rudest words possible, without even trying. I can't for the life of me make it through a game without spotting labia, or sighing as I realise I'm just one letter away from spelling testicle. Why can't I spot clever words like deracinate (to uproot), or recidivism (a tendency to lapse into a previous condition or pattern of behaviour)? Perhaps it's because - ooh, hold on, I just got cocks.
