Ten iPhone Apps Worth Paying For

WordsWorth is a good word game. You form words by tapping letters on the screen. Longer words using rarer letters (such as J, Z, and Qu, for example) score more points than shorter words with more common letters.

To make things interesting, the app includes certain special tiles, such as blue wild cards, green bonuses, and red timers. A gold tile helps you grow your score. The timer tiles are the most insidious; if their time runs out before you’ve used the letter, the game is over.
