Word Soup ($2.99), by Fuzzy Bug Interactive. Like all active content so far, requires an updated K2/KDX or any K3 and only available to those in the US.
Game Description
Word Soup is a word search game with a tactical twist.
Create words within the grid of scrambled letters. Each word created is removed from the grid and the letters above fall into the gaps left behind, creating new word combinations. With careful play, letters can be strategically brought into play and used to create longer words. You score bonus points if you can successfully clear the grid of all letters. The starting grid is randomly generated, so no two games should ever be the same.
Word Soup offers two modes of play: 'Relaxed' - for those who like to take their time and try to create the longest words, and 'Timed' - where players can test themselves against the clock to see how they score under pressure. Your 'Longest Word', 'Highest Scoring Word', 'Words Made' and 'Total Score' stats are all tracked. Word Soup can be played in Portrait, as well as Landscape view.
