There are three words on which to focus here. We’ll go in reverse. “Aurora” is an effect. The playing field shimmers and glows like the Aurora Borealis, only with moving stars. “Solitaire” is the game on which this is based, as it’s played much like the klondike variation. But here, “Words” replace numbers. So, rather than create columns of descending numbers, you’re flipping cards in hopes of spelling out words.

Three games from one maker: one a familiar puzzle game, one a time test of single-finger typing, and the last a truly unusual combination of spelling and mazes.

WordsWorth is a word game that’s well suited for the iPhone’s touch screen, and better suited for those who savor “The Joy of Lex.” The game presents you with a grid of tiles, each containing a letter. The grid ranges from 4×4 to 7×7, depending upon your preference. It’s your job to link the letter tiles to form words. You can’t move the tiles, though, and the letters of the word must be touching each other in the order in which the word is spelled. The longer the word and the more rare the letters in the word, the more points you get. It’s a lot like Scrabble in that way, only you’re forced to find words instead of create them.

You may think you have a large vocabulary, and you probably do, but tapping it while staring at a jumbled mess of letters isn’t always so easy.
