Not all iPhone games require you to pay 99 cents or more to download 
them. So what are the best free games for the iPhone? These selections 
are worth paying for even though they won’t cost you a dime.

Who would have though that Apple’s iOS platform was the perfect platform for extended games of 
Scrabble-like board games? Words With Friends Free is exactly that -- a brand of 
Scrabble
 that you can play against your friends by taking turns, over the 
Internet, at your own pace. Each player places a word and submits it to 
Words With Friends, which vets it to make sure it really is a word, and 
keeps score. You can play up to 20 games at a time, with as much time as
 you want between turns -- it’s all up to you. And best of all (yes, 
better than free), you can play Words With Friends cross-platform, 
against players on Android phones as well as iPhones or iPads.

Mentioning
 Angry Birds here feels like paying homage to the king, but the free 
version of Rovio Mobile’s inescapable and iconic casual bird-flinging 
masterpiece is actually a really solid game. First off, it features 15 
levels that aren’t available in any other version of the game, which is 
at least something of an incentive to check it out. Secondly, it 
features the same very solid gameplay mechanics that make the paid 
version of Angry Birds work so well. Angry Birds Free is ad-supported 
and not nearly as cool as the full version of the game -- that sometimes
 gets updates with additional levels -- but it is a free version of 
Angry Birds that rewards your frugality with unique stages to play 
through.

Anyone
 who’s given Sudoku a try in the puzzles section of a newspaper knows 
how addictive it can be. The logic game has a simple premise, yet can be
 incredibly difficult. You have a grid of 81 squares, and that grid is 
divided into larger blocks that each contain nine squares. The key to 
the game is to make each column, row and block contain all numbers 1 
through 9 without repeating. Once you understand the rules (for example,
 when you fill in a blank square with a 6, there can’t be another 6 in 
the same line either horizontally or vertically), the game becomes 
interesting as you start to use logic to fill in blank squares and 
eliminate numbers that could potentially fill them. Sudoku 2 is a 
beautiful, free way to play Sudoku on your iPhone, and it’s as addictive
 as it is elegant. The game provides all the features you would get if 
you were playing with a pen and paper, including the ability to mark 
squares with hypothetical numbers that 
could occupy them as you
 continue to eliminate options. It’s packed full of puzzles of varying 
difficulties and seems to go on forever.

There
 are tons of puzzle levels in Unblock Me Free, even though it’s a demo 
game for its paid counterpart. The premise is simple, even though the 
game is challenging: in each square level, you have a series of wooden 
rectangles that are placed together in the grid. One of the pieces is 
colored, and this one you’re trying to slide off the screen. The blocks 
can move horizontally or vertically, but only in the direction that 
they’re smallest side is facing – in other words, you can’t move the 
blocks sideways. Even the beginner puzzles are a decent challenge. 
Unblock Me has an addictive nature that will draw you into its free 
puzzle-solving charms for a good long time.

After the hugely successful 
Words With Friends, Zynga’s new take on the traditional hangman game is another winner. With the same drop-in-and-play vibe as 
Words,
 it’s a game that players can dip in to at their own pace. Create words 
for your opponents and see if they can solve them. There are lifelines 
and hints available if you get stuck (plus an in-app store where you can
 buy more coins), but get five words wrong in a game and you’ll lose. 
This word game doesn’t pack the same strategic punch as 
Words With Friends, but it’s still fun to pick up and play now and again.

The follow up to mega-hit 
Paper Toss
 offers even more time-wasting fun for free. The original game was 
downloaded more than 100 million times, but the sequel takes things to a
 new level. More than just paper, you get to throw bananas, grenades, 
tomatoes and more, all in new, improved settings with crisper, cleaner 
graphics. The game’s dynamics remain similar, but the gameplay has been 
refreshed and improved to increase replayability. Factor in more 
power-ups, more people to throw things at, more unlockable items and 
Game Center leaderboards and Paper Toss 2.0 adds up to a heap of fun.

Here’s a prediction. A few minutes with the free, trial version of 
Fruit Ninja, and you’ll probably want to fork out the 99 cents for the 
full experience.
 Fruit Ninja Lite lets you sample just the classic mode, but omits the 
excellent arcade, Zen and multiplayer modes avaiable in the paid-for 
version. Still, what you get for free is a lot of fun: as fruit flies 
across the screen you must slash it with your finger like a samurai, but
 watch out for bombs or it’s game over. It’s a dynamic that’s perfectly 
suited to the iPhone’s touchscreen and furiously addictive.

There’s
 an awful lot to explore in Six-Guns, and what’s more, it’s all free. 
Sure, you can use in-app purchases to speed things up a bit, but 
developers Gameloft make it clear in their description that you can play
 through the entire game without spending a dime. Set in an old West 
environment, Six-Guns is an open-world cowboy adventure with plenty of 
varied missions to enjoy, usually involving gun-totin' and horseback 
ridin'. Though the storyline and plot isn’t the greatest, play often and
 your character will gain access to better weapons and you can hone your
 cowboy skills no end.

Developer
 Zynga hit the jackpot with this one — it’s the most popular Texas 
Hold’em poker game in the App Store and on Facebook with an an estimated
 6 million people playing their hands every day. If you’re just a 
beginner, it’s easy to pick up and learn, but if you’re a more seasoned 
card shark, there are also plenty of competitive tables available. It’s 
easy to chat with your fellow players and various tournaments could see 
you winning thousands of chips to keep you playing that little bit 
longer.

This free, trial version of 
Amazing Breaker,
 is an excellent physics-based puzzler with plenty of ice-smashing 
action. There’s 16 levels to try here, and you’re pretty likely to get 
hooked and want to upgrade to the full game. With universally positive 
reviews, this challenging puzzle game sees you blasting ice sculptures 
with bombs. You need to destroy at least 90 percent of each sculpture to
 move on, so the trick is to demolish every little fragment of ice, and 
therein lies the challenge. It’s easy to learn, but hard to master like 
the best and most addictive games.
