"There are many, many free iPhone games, but how many of them are any good? Once you discount the increasing number of Lite demo versions of paid-for titles, not so many.
Yet there's clear proof that iPhone gamers love a bargain, and all the more so if it's free. With that in mind, we've been trawling the App Store for fun, innovative and intriguing free games, and produced a list of the top 20.
There've been some impressive new releases since we last did this kind of roundup. No Lite demos are included, although some of these games (Live Poker and Space Monkey for example) do have versions available that you pay for - they get in here because the free versions are full games in their own right."
