I've been playing Words with Friends and am just starting a game with someone who I just realized is a gal I don't want to play games with. We have kind of a history. She's sly, though, not having a real name associated with her Words with Friends account, so it was only a mutual friend who told me. Now I want to resign the game. How do I do that on my iPhone?

I've written in the past [see My Favorite iPhone Games] about Plants vs. Zombies, an entertaining puzzle game where you have an ever-increasing variety of plants, pea shooters, etc., that are your only defense against swarms of staggering zombies. It could have been potentially gory, but fortunately it's all cartoon images and there's a sense of zany fun to the game that makes it compelling.

It's also widely available, on Mac, PC, iPhones, iPads, etc. In fact, it's the iPad version that was sufficiently compelling that I actually played through the entire game and finished it up, then went back and tried to optimize my approach on some of the hardest levels.

Just in time for the holidays, PopCap has released a new "Game of the Year" edition of Plants vs. Zombies. Is it worth buying if you already have PvZ?

Another game for the iPhone? I already have over a hundred games on my iPhone (one reason my kids are always stealing my phone!) so when my friend Gary dropped me a note to let me know that his long-time hit Gold Strike [iTunes link] was now available through the iPhone App Store, I was skeptical. He writes great games but still, another game? Fortunately, I sprang for the $0.99, dropped it onto my phone and am impressed!

I've written a lot about iPhones, and traveled down many different routes in terms of how to use them efficiently, how to have fun, and how to solve a wide variety of problems or glitches. If you've watched closely, you'll have also see in the screenshots that I have a lot of iPhone apps on my phone, in fact I think I've maxed out the number of screens I can create on the 3GS device.

Most of those apps? Games. I have a lot of games for my iPhone and while many of them are intended to keep my kids entertained (their favorites currently are Surviving High School, Cooking Mama, Oregon Trail, Sally's Spa and Pocket God) there are definitely some that I have added for my own enjoyment.

Peggle has you shooting a ball to bounce off, and thereby eliminate, red pegs on screen

Enter iPhone and computer game developer Popcap. I started out downloading Peggle and then finishing the game -- three times through! -- and asking them to release a new version so I could continue to play. Instead, they told me that they'd released a new game and wanted me to try it: Chuzzle.

I just recently downloaded the game "Besieged" for my Apple iPhone but am stumped, unable to get past the last boss. Is there some trick or walkthru or something you can point me to, Dave?

I'm going back and forth on whether to spend the money and buy myself an Apple iPhone. In a lot of ways it seems like a very cool phone, and certainly it has far more features than my clunky old LG. I know about the core functions, but my first glance at the iPhone Application Store was totally overwhelming. I mean, there are HUNDREDS of applications. Tell me, what are your favorites and do you stick just to free apps, or have you bought some too?
