First off, you could stop by our Price Drops, Must-Have Freebies, and Deals Forum where we've got an army of dudes combing the App Store to find cool games on the cheap (or free). If you want to get a little more proactive, you can go scoping for deals yourself. How we do this when we post about sales is by utilizing our sister site, AppShopper.
Here are some handy links:
- All games with price drops.
- Popular games with price drops.
- All previously paid games that have been made free.
- Popular games that were previously paid that are now free
Watching the previous two freebie links can yield some particularly great results, as you can often find games that go free before whatever freebie promotions those particular games might be doing even technically start. Similarly, I've heard tales of some people being able to snag great games that were accidentally marked to free.
As far as the differences between "all" games and "popular" games, that all has to do with a top secret algorithm that attempts to determine what kind of games people are interested in. Personally, I tend to lean towards just wading through all games as sometimes you find some really crazy stuff in there.
Alternatively, you could just download the AppShopper App [Free] which also is pretty great for finding deals.
